Add a floor,
not a footprint.

A second-story addition is the only way most South Florida homes can grow once setbacks have used up the lot — and it is the most structurally demanding addition a house can take. Elbaz Construction engineers it before designing it: foundation capacity, load path and wind-load tie-in are settled first, then the drawings, the permit, the build and the final inspection follow under one contract.

The only direction left to build is up.

On a Miami-Dade or Broward infill lot, the setbacks usually run out before the family does. A second story adds permitted, insurable square footage without buying another foot of land.

Elbaz Construction treats a second-story addition as a structural engineering project first and a construction project second. A licensed structural engineer establishes whether the existing foundation and first-floor walls can carry the new loads before any design is committed — that assessment, not an optimistic sales visit, is what sets the scope, the sequence and the budget.

What you actually gain

Square footage that stays on your lot.

Building up changes what the house can do without changing what the property is. These are the outcomes worth weighing before scope, and the trade-offs worth weighing with them.

Twice the house.
The same yard.

A ground-floor addition spends lot area to buy interior area. A second story does not — the pool deck, the driveway, the setback buffer and the mature planting all stay where they are. On a tight South Florida lot that is frequently the difference between an addition being possible and an addition being denied.

  • Bedrooms, a primary suite or a home office added without losing outdoor space.
  • Living, cooking and entertaining stay together downstairs; sleeping moves up.
  • Upper-level rooms gain daylight, cross-ventilation and, on many lots, a view.
  • The additional square footage is permitted and reflected in the property record.

One upgrade, two benefits

Carrying a new floor usually means retrofitting shear-wall sheathing, hold-downs and connectors into the existing first floor. That work is done to current Florida Building Code wind-load requirements — so the original structure is strengthened as a consequence of the addition, not separately.

Value that is documented

Permitted square footage, a closed-out permit file and current wind-mitigation documentation are what an appraiser, an insurer and a future buyer can actually read. Unpermitted work is the opposite: it usually costs value rather than adding it.

Daylight is the part nobody budgets for.

An upper level sits above the neighbouring hedge line, the carport roof and the screen enclosure. The rooms that go up there get glazing the ground floor could never have had — which is why the window and door package is worth deciding early, with the structural engineer in the room, rather than during finish selections.

Second story, or a ground-floor addition?

They are not interchangeable, and the honest answer is usually decided by your lot rather than your preference. We compare the two side by side further down this page, including the cases where building outward is genuinely the better call.

Illustrated project sequence

How a second story actually goes up.

One South Florida house, followed from the first structural visit through to the reinforcement that lets the original walls carry another floor. Every stage below is one that a real second-story addition has to pass through.

Where most of these projects start: a well-kept single-storey house on a lot with no room left to build outward. The garage, entry, driveway and palm stay exactly where they are through every frame that follows.

AI-assisted visualization illustrating a typical second-story addition process. Structural requirements and finished results vary by property. These are generated images, not photographs of a completed Elbaz Construction job — we hold no verified photo set of a finished second-story addition and we are not going to imply otherwise. The sequence is here because the order of operations is the part homeowners most often have not seen, and it is accurate to how the work runs.

Structural engineer evaluating an existing South Florida home for a second floor
The first real step is not design. A structural engineer and the contractor measure the existing walls and check the foundation before anything is drawn, because what they find decides the scope.
Existing footing investigation for a proposed second-story addition
A small, controlled test excavation exposes the existing footing so its depth and condition can be measured rather than assumed. This is what tells you whether underpinning is required.
Architectural and structural planning for a residential second-story addition
Only once the structure is understood does the design begin — layout, stair position, bearing lines and the upper-floor plan, coordinated between the architect and the engineer.
Construction documents being reviewed for a second-story addition permit
The drawing set, the structural sheets and the product-approval documents are assembled and checked before submission. Incomplete applications are the most common self-inflicted delay on the whole job.
Temporary shoring and site protection before opening a home's roof
Before the roof is touched: fencing, protected planting, a covered entry, staged materials and temporary shoring inside the house. The existing roof is still on.
Controlled roof removal during a South Florida second-story addition
The disruptive phase. A defined section of roof comes off while the rest stays intact, with weather protection sheeted and battened down and the structure shored beneath.
First-floor wall reinforcement supporting a new second-story addition
The least visible and most important work: the existing first-floor walls get structural sheathing, hold-downs, connectors and a new beam so they can carry loads the original construction was never designed for.

Your house. Every property's foundation, walls and roof differ, and the scope follows what the engineer finds on site
01

The starting condition

A single-storey house on a lot where the setbacks have already been used up. Nothing is wrong with it — it simply has no room left to grow outward. That is the situation a second story exists to solve, and it is the one part of the project that is genuinely the same on nearly every job we look at.

02

What has to be established first

Whether the existing foundation and first-floor walls can carry another floor. That question is answered by a licensed structural engineer measuring and, where necessary, exposing the footing — not by a contractor's visual guess on a first visit. The finding sets the scope, the sequence and the budget before any design is committed.

03

How the second level is carried

The upper floor is a structural deck spanning between bearing walls, not a platform resting on the roof below it. Loads from the new roof, the floor, and the people using them run down through the second-floor framing into the first-floor walls, into the footings and finally into the soil. On an addition every one of those elements already exists and every one has to be checked.

04

Why the order matters

Engineering before design, design before permitting, shoring before demolition, reinforcement before framing. Reversing any two of those is how a second-story addition turns into a redesign, a re-permit and a schedule reset — which is the single most expensive mistake available on this type of work.

Want to know whether your house can carry a second floor?

That question has a real answer, and it comes from a licensed structural engineer looking at your foundation and first-floor walls — not from an illustration of somebody else's project.

Scope and upgrade paths

Three honest ways this can be scoped.

These are planning tiers, not products. Elbaz Construction does not publish fixed second-story packages or fixed prices, because the structural findings on your house decide most of the scope before anybody chooses a finish.

Standard scope

The addition itself, built correctly

The vertical build with no discretionary changes to the existing home beyond what the structure and the code require.

  • Structural feasibility study and engineered drawings
  • Permit set, submission and review-comment responses
  • Temporary shoring and weather protection during roof-open work
  • Second-floor framing, dry-in and wind-load tie-in
  • Code-required shear-wall retrofit to the existing first floor
  • Stair, MEP extension, insulation, drywall and standard finishes
  • Inspections through final and permit closeout

Enhanced scope

The addition plus the first floor it lands on

Adds the first-floor work that a second story tends to make sensible to do at the same time, while walls are already open.

  • Everything in Standard scope
  • First-floor layout changes around the new stair location
  • Electrical service and panel upgrade for a two-storey load
  • Zoned or second-system HVAC rather than extending one system
  • Full re-roof of the existing structure for a matched, warrantable assembly
  • Impact window and door replacement on the existing floor to match the new
  • Upgraded insulation and air-sealing across both levels

Premium scope

A two-storey house, not a house with a floor on top

Treats the finished result as one home rather than old-plus-new, including the exterior envelope and the interior specification.

  • Everything in Enhanced scope
  • Architectural redesign of the whole exterior elevation
  • Primary suite build-out with custom joinery and stone
  • Second-floor terrace, balcony or roof-deck construction
  • Elevator or future-elevator shaft provision
  • Whole-home smart, security and AV infrastructure
  • Landscape and hardscape reinstatement after construction access

Add-ons and upgrades, priced individually

  • Structural underpinning — helical piers or micropiles where footing capacity is short
  • Engineered floor trusses or I-joists in place of conventional framing
  • Structural steel or LVL beams to carry new point loads to the foundation
  • Additional shear-wall sheathing and hold-down hardware beyond the code minimum
  • Impact-rated glazing upgrades and product-approval documentation
  • Second-floor laundry, wet bar or kitchenette rough-in
  • Sound isolation between floors — resilient channel or floating floor assemblies
  • Temporary accommodation coordination during the roof-open phase

Scope tiers are a way to have a clear conversation, not a price list. Any of these line items may be required, optional or irrelevant on your house depending on what the structural feasibility study finds — which is why we do that study before quoting scope, not after.

From structure to handover

And how it finishes.

The same illustrated project, continued: the new floor goes on, the walls and roof follow, the house is closed in, and the work becomes ordinary construction again.

01

The floor system goes on

Engineered joists span the reinforced bearing lines and are decked. This is the piece a second-story addition is genuinely adding, and it is why the walls below had to be strengthened first.

Upper-level wall framing and stair opening for a second-story addition
02

Upper walls and the stair

New stud walls, window openings framed to match the rhythm below, and the stair opening cut through the deck. The stair has to land somewhere on the first floor — that decision reshapes existing rooms.

Roof framing and the tie-in

Engineered roof trusses, bracing, and hurricane connectors strapping the roof down through the walls to the foundation. This is the load path the whole project is built around.

Process and client experience

Ten stages, and what each one asks of you.

A second-story addition is long enough that knowing what happens next is worth as much as knowing what it costs. This is the sequence, what we do, and where a decision is genuinely yours to make.

Initial consultation

We walk the house with you, listen to what the space needs to do, and say plainly whether a second story is the right instrument for it.

What to expect

About an hour on site. Bring anything you already have — a survey, old permits, an appraisal, a sketch.

Your decision

Whether to proceed to a paid structural feasibility study.

Site review and measurement

Existing conditions are measured and documented: foundation type where visible, wall construction, roof framing, service locations, setbacks and site access.

QC · Existing conditions are recorded before anything is designed.
What to expect

Access to the attic, the electrical panel and the perimeter of the house.

Your decision

Nothing yet — this stage is fact-finding.

Structural feasibility study

A licensed structural engineer assesses whether the existing foundation and first-floor walls can carry a second floor, and what reinforcement is required if they cannot.

QC · This is the gate. Design does not start until it is passed.
What to expect

A written finding, not an opinion. It may say the project needs underpinning — better to know now than after demolition.

Your decision

Whether the reinforcement scope is one you want to take on.

Scope and design

Plans are developed around the engineer's findings — layout, stair location, elevations, window and door schedule, and how old and new meet.

What to expect

Several rounds of review. Layout and stair position are the decisions with the largest downstream effect.

Your decision

Layout, stair location, matching or contrasting the existing exterior.

Estimate and proposal

An itemised proposal is prepared against the drawn scope, with allowances stated as allowances rather than buried in a lump sum.

What to expect

A document you can compare like for like against another contractor's, provided theirs covers the same scope.

Your decision

Scope trade-offs, allowance levels, and whether to use financing.

Planning and permits

Engineered drawings, product approvals and the permit application are assembled and submitted; we respond to plan-review comments until the permit issues.

QC · Product approvals and engineering are checked before submission, not after a rejection.
What to expect

Waiting. Review timelines belong to the building department, and no contractor controls them.

Your decision

HOA or architectural-committee submission if your community requires one.

Scheduling and preparation

Trades are sequenced, long-lead products are ordered, protection is planned, and the roof-open window is scheduled around weather.

What to expect

A start date, a sequence, and a decision about whether you are staying in the house.

Your decision

Whether to relocate during the most disruptive phase.

Construction

Shoring, roof removal, second-floor framing, tie-in, dry-in, then MEP extension, insulation, drywall and finishes.

What to expect

Noise and dust during the structural phase, then a quieter, more predictable finish-out once the house is weather-tight.

Your decision

Finish selections, confirmed early enough not to hold the schedule.

Quality control and inspections

Our own checks run alongside the building department's: structural connections, dry-in, rough MEP, insulation, and final.

QC · Connections and tie-ins are photographed before they are covered.
What to expect

Inspections are scheduled and attended by us. You do not have to be there.

Your decision

Nothing — unless an inspector's comment changes something you chose.

Final walkthrough and closeout

We walk the finished addition with you, agree and complete a punch list, and close the permit out so the square footage is on record.

QC · Nothing is called complete until the permit is closed.
What to expect

A closed permit file, warranty documentation, and current wind-mitigation paperwork for your insurer.

Your decision

Sign-off, once the punch list is genuinely finished.

We do not promise approval times for any building department, and we do not quote inspection dates we do not control.

Planning, permitting and risk reduction

Most delay is decided before anyone lifts a hammer.

Nearly every avoidable second-story delay traces back to something that was skipped, assumed or left until later during planning. This is the paperwork sequence, and why each step exists.

The paperwork sequence, in order

  1. Measured existing conditionsDimensions, wall construction, roof framing and service locations recorded on site rather than taken from an old survey.
  2. Structural engineeringFoundation capacity, load path and any required underpinning or shear-wall retrofit, signed and sealed.
  3. Design documentsFloor plans, elevations, sections and the structural set that a plan reviewer will actually read.
  4. Scope confirmationA written scope both sides agree on before pricing, so the estimate and the drawings describe the same project.
  5. Product approvalsFlorida Product Approval or Miami-Dade NOA documentation for impact windows, doors and roofing assemblies.
  6. HOA and architectural reviewWhere a community requires it, submitted in parallel with the building department rather than after it.
  7. Permit submissionA complete application — incomplete submissions are the most common self-inflicted delay in the whole process.
  8. Review commentsPlan-review comments answered by the engineer and designer who produced the drawings, not passed back to you.
  9. Inspection schedulingStructural, dry-in, rough MEP, insulation and final, sequenced so trades are not waiting on each other.
  10. Change managementAny change priced and documented in writing before it is built — including changes an inspector requires.
  11. DocumentationPhotographs of connections and tie-ins before they are concealed, kept with the job file.
  12. Permit closeoutThe final inspection passed and the permit formally closed, so the added square footage exists on the record.

Why each step exists

Why the engineering comes first

Underpinning discovered after design is a redesign, a re-permit and a schedule reset. Discovered before design, it is a line item.

Why product approval matters early

An impact window without valid approval documentation will not pass. Sorting it at submission costs nothing; sorting it at inspection costs weeks.

Why scope is written down

Two proposals for “a second story” can differ by an entire shear-wall retrofit. A written scope is what makes them comparable.

Why changes are priced in writing

Verbal changes are how projects end in disputes. Priced, signed changes are how they end in a closed permit.

What we will not tell you

We will not promise you a permit approval date, an inspection date, or a review timeline — those belong to the building department and no contractor controls them. We will not tell you a second story is straightforward before an engineer has looked at your foundation. And we will not quote a number before there is a scope to attach it to.

Cost and timeline transparency

What moves the number, and by how much.

We do not publish second-story prices, because a published price for this work is a guess dressed as a fact. What we can be specific about is which variables move your number most — so you can see where your project is likely to sit before anyone quotes it.

Foundation reinforcement

Whether the existing footings can carry a second floor, or need underpinning with helical piers or micropiles. The single largest swing on the whole project, and the reason the feasibility study comes first.

Shear-wall retrofit extent

How much additional structural sheathing, hold-down hardware and connector work the existing first-floor walls need to meet current wind-load requirements.

Roof scope

Tying new framing into an existing roof usually makes a full re-roof of the whole house the practical choice, for matched materials and continuous warranty.

Stair location

The stair has to land somewhere on the first floor. Where it lands often means reworking existing rooms, structure and services below.

MEP extension

Plumbing stacks, electrical service capacity, panel size and HVAC zoning for two storeys rather than one.

Project size and complexity

Square footage matters less than shape: roof planes, level changes and cantilevers cost more per square foot than a simple rectangle.

Materials and specification

Impact glazing packages, floor framing type, and interior finish level. Real, but usually smaller than the structural variables above it.

Site access and staging

Whether a crane, a pump or a lift can reach the work, and where materials and waste can be staged on a tight lot.

Existing conditions

What is found once walls and roof are opened — older wiring, undersized framing, prior unpermitted work, moisture or termite damage.

Specialty and product lead times

Impact windows and doors, engineered trusses and structural steel are ordered against schedules, not pulled off a shelf.

Low Moderate High Very high

Typical influence on a South Florida second-story budget. General guidance for planning conversations — not a quote, and not a substitute for an engineered scope on your house.

What actually moves the schedule

  • Engineering and design resolution — routinely longer than the square footage suggests, because the structure has to be settled before permitting.
  • Building-department review and any resubmittal cycles, which are outside any contractor's control.
  • Long-lead products — impact windows and doors, engineered trusses, structural steel.
  • The roof-open window, which is weather-dependent and scheduled conservatively for that reason.
  • Change orders introduced after construction starts, which reset sequencing as well as cost.

Questions worth asking any contractor

  • Who is the licensed structural engineer on this project, and when do they assess the foundation?
  • Is a shear-wall retrofit of the existing first floor included, or excluded?
  • Does the estimate include a full re-roof, or only the addition's roof?
  • What is an allowance here, and what is a fixed price?
  • How are change orders priced and documented before they are built?
  • Who submits the permit, and who answers plan-review comments?
  • What happens to the permit at the end, and who closes it out?

How to prepare for an accurate estimate

  • Find the survey, any prior permits, and the original plans if the house has them.
  • Note anything you already know is non-standard — additions, a converted garage, prior unpermitted work.
  • Decide roughly how many rooms you need upstairs and what they are for.
  • Decide whether staying in the house during construction is realistic for your household.
  • Confirm whether your community has an HOA or architectural review committee.
  • Sort financing in principle before design, so scope and budget are decided together.

Estimates follow scope, not the other way round.

We price against a drawn scope and a structural finding, with allowances stated as allowances. That is what makes a proposal comparable to anyone else’s.

How a second story is carried

The load path, drawn.

Everything a second-story addition adds — the roof, the floor, the walls, the furniture and the people — has to reach the ground through the house that is already there. This is that path, and the point at which each part of it is checked.

Load path of a second-story additionA vertical diagram in six stacked bands. Load travels downward from the new roof and roof framing, into the second-floor framing, into new bearing walls and beams, into the existing first-floor walls, into the existing foundation and footings, and finally into the bearing soil. The upper three bands are new construction; the lower three are existing construction that must be checked and, where required, reinforced.NEW ROOF AND ROOF FRAMINGNew constructionSECOND-FLOOR FRAMINGNew constructionNEW BEARING WALLS AND BEAMSNew constructionEXISTING FIRST-FLOOR WALLSExisting constructionEXISTING FOUNDATION AND FOOTINGSExisting constructionBEARING SOILExisting constructionLOAD DIRECTION

Diagram drawn by Elbaz Construction for this page. It is an explanatory illustration of a general load path, not an engineered drawing of any specific house.

Every band is a check

  • New roof and roof framing. The addition's own roof assembly, tied into the existing structure and rated for current wind loads.
  • Second-floor framing. Engineered floor trusses, I-joists or conventional framing spanning between bearing lines — the floor system that is genuinely being added.
  • New bearing walls and beams. Where the new plan does not stack over existing walls, steel or LVL beams carry the load across to points that do.
  • Existing first-floor walls. Frequently need retrofitted shear sheathing, hold-downs and connectors to carry loads the original construction was never designed for.
  • Existing foundation and footings. Assessed for depth, capacity and condition. Where capacity is short, helical piers or micropiles extend it before the second story is permittable.
  • Bearing soil. The end of the path. Everything above it is only as good as what it lands on.
Where most projects turn

The two existing bands — first-floor walls and foundation — are where a second-story addition is decided. Everything above them is ordinary construction; everything about them is why a structural engineer looks first.

Comparison, mistakes and buyer guide

The decisions people get wrong, and how not to.

Second story compared with building outward

Second-story addition compared with a ground-floor addition of the same size. General guidance for South Florida — your lot, your zoning and your existing structure decide the real answer.
FactorSecond-story additionGround-floor addition
Lot impactNone. Yard, pool deck, driveway and setback buffer are untouched.Consumes lot area and may be limited or blocked outright by setbacks.
Foundation workExisting footings must be assessed and may need underpinning.New footings for the new area; the existing foundation is usually untouched.
Existing structureFirst-floor walls often need shear-wall retrofit to current wind-load code.Existing walls usually carry no new vertical load.
Roof impactThe existing roof is opened and a full re-roof is commonly triggered.Usually a tie-in at one elevation; the rest of the roof is left alone.
Living through itThe most disruptive phase opens the roof — relocation is worth considering.Work is largely outside the existing envelope until the tie-in.
Cost profileDriven by structure: engineering, reinforcement, shoring, roof.Generally lower per square foot for the same finish level.
When it makes senseWhen the lot has no room left, or the view and daylight upstairs are the point.When the lot has room and the budget is better spent on space than structure.

Match the existing, or contrast it

Matching or contrasting the existing exterior — a design decision with real cost and resale consequences.
FactorMatch the existingContrast deliberately
Reads asOne house, built at one time.Two eras, intentionally expressed.
Material riskDiscontinued finishes and weathered colour are hard to match exactly.No matching required, so no matching risk.
DetailingTransitions between old and new assemblies must be hidden.Transitions become a designed joint rather than a concealed one.
ResaleSafest for conventional buyers and appraisal comparables.Rewards good design; punishes half-committed design.

The mistakes that cost the most

  1. Choosing on price aloneThe cheapest second-story proposal is usually the one that has not priced the shear-wall retrofit or the re-roof.
  2. Comparing proposals with different scopesTwo numbers only mean something if both include the same engineering, reinforcement, roof and allowances.
  3. Designing before engineeringPlans drawn before the foundation is assessed get redrawn when the assessment arrives — and re-permitted.
  4. Treating permits as paperworkIncomplete submissions and missing product approvals are the most common self-inflicted delay on the whole job.
  5. Leaving material decisions lateImpact windows, trusses and steel are ordered against lead times. A late decision stops the site, not just the order.
  6. Underestimating the stairThe stair lands on the first floor and takes rooms, structure and services with it. It is a plan decision, not a finish decision.
  7. Making design changes after framingA change during framing touches structure, MEP and inspections at once, and resets sequence as well as cost.
  8. Forgetting the insurance and appraisal fileNew square footage without a closed permit and current wind-mitigation documentation is worth less, not more.

Buyer checklist

Prepare before you call

Ask at the first meeting

Expect from a qualified contractor

Tick these off as you go — nothing is stored or sent, the list is here purely so you can use it while you compare contractors.

What the build is like

Before you live through it, know what it looks like.

Controlled roof removal during a South Florida second-story addition
Illustration of the roof-open phase from the sequence above, not a photograph of a completed Elbaz Construction job. We hold no verified video or photo set of a finished second-story addition; what is described in the panel beside it is how we actually run the work.

The disruptive part is short and identifiable

The roof-open phase — shoring, removal, framing and dry-in — is the loud, dusty, weather-exposed part. It is scheduled tightly for exactly that reason, and once the house is dry the job becomes ordinary construction.

Preparation you can do

Clear the work zone and the perimeter, move anything fragile off shared walls, plan where pets and home offices go, and agree parking and staging before day one.

How communication runs

One point of contact, a known schedule, and notice before anything that affects power, water or access. Questions go to the person running the job, not a call centre.

Quality control, not just inspection

Structural connections and tie-ins are checked and photographed before they are covered. Building-department inspections confirm the work; they are not the only time anybody looks at it.

What completion means

A finished punch list, warranty documentation, current wind-mitigation paperwork, and a permit that is formally closed — so the square footage exists on the record.

Questions, answered

Second-story additions in South Florida.

  • It depends heavily on the existing foundation and first-floor wall structure. Homes with adequate footing depth and sound framing can often be built up directly; older or lighter-built homes sometimes need foundation underpinning or first-floor shear-wall reinforcement before a second story is structurally permittable.

    That determination comes from a licensed structural engineer's assessment, not from a contractor's visual guess on a first visit.

  • We do not publish a price, because the honest answer is decided by your structure rather than your square footage. Foundation reinforcement, the extent of shear-wall retrofit and whether a full re-roof is triggered move the number far more than finish selections do.

    The cost-driver breakdown further up this page shows which variables carry the most weight, and an itemised estimate follows the structural feasibility study.

  • Structural feasibility and design usually take longer than the addition's size suggests, because the engineering has to be resolved before permitting. Construction itself commonly runs several months to a year depending on how much foundation reinforcement is required and whether the whole roof is being replaced.

    We do not quote building-department review times, because no contractor controls them.

  • Not always. The most disruptive phase — when the existing roof is opened to tie in the new floor — often makes at least temporary relocation worth considering, particularly with young children or anyone sensitive to construction dust.

    Some households stay through it with the upstairs and certain rooms off-limits. We walk through the sequencing during planning rather than after demolition starts.

  • Often, yes. Tying new roof framing into an existing roof typically requires removing enough of the original roof that a full re-roof of the whole house becomes the practical and often code-driven choice — for matching materials, continuous flashing details and warranty coverage that actually holds.

  • Yes. New construction, including a second-story addition, has to meet current Florida Building Code wind-load requirements regardless of when the original structure was built.

    That is frequently why first-floor walls need shear-wall reinforcement — to carry loads the original 1970s or 1980s framing was never designed for.

  • Engineered floor trusses or I-joists for the new floor system; structural steel or LVL beams to transfer new point loads down to the foundation; helical piers or micropiles where existing footing capacity is short; retrofitted shear sheathing with hurricane ties and hold-downs on existing first-floor walls; impact-rated windows and doors; and a roofing system matched or coordinated with the existing structure.

    Temporary shoring and weather-protection systems are used during the roof-open phase and are part of the scope, not an extra.

  • A building permit supported by sealed structural drawings, and product-approval documentation for impact windows, doors and roofing assemblies. Inspections typically include structural, dry-in, rough mechanical, electrical and plumbing, insulation, and final.

    We prepare and submit the application, respond to plan-review comments, schedule and attend inspections, and close the permit out at the end.

  • Yes — financing options are available through Mosaic, and we can point you at the application before design begins. Sorting financing in principle early means scope and budget get decided together rather than the scope being cut late.

  • Manufacturer warranties apply to installed products — roofing assemblies, impact windows and doors, and mechanical equipment — and the specific terms come from those manufacturers with the documentation handed over at closeout. Workmanship coverage is set out in your contract; ask for it in writing and read what it covers before you sign, with us or with anyone else.

  • Mostly the ordinary South Florida list applied to more building: keep the roof and flashings inspected after storm season, keep sealant joints around impact windows and doors sound, keep drainage running away from the foundation, and service the additional or re-zoned HVAC equipment on schedule.

    Keep the closed permit file and wind-mitigation documentation somewhere you can find it — your insurer and, eventually, your buyer will both ask.

  • It can. Increased square footage and rebuild value typically mean a policy update, and depending on how the roof and structural connections are built, wind-mitigation inspection results may change too. Have your agent review the completed wind-mitigation documentation once the project closes out.

Start here

Find out whether your house can carry a second floor.

One conversation, then a real structural answer. No pressure, no countdown, and no number quoted before there is a scope to attach it to.

What happens after you send this

  1. We call you back to understand the house and what the space needs to do.
  2. We walk the property, measure existing conditions and look at the foundation and first-floor structure.
  3. A licensed structural engineer establishes feasibility and any reinforcement required.
  4. You get an itemised scope and estimate written against that finding — not against an assumption.

Worth having to hand

  • Your property survey
  • Any prior permits or original plans
  • A rough idea of rooms and uses upstairs
  • Whether you can stay in the house during construction
  • HOA or architectural review requirements, if any
