Yes, you can customize a floor plan, and most of our clients do. Our existing plans are starting points, not fixed products. Which changes are simple, which ones need new engineering, and when it makes more sense to design from scratch all depend on what you want to change. This guide goes through the three levels of change, the changes clients ask for most, what each one means for cost and schedule, and the seven questions we use to decide between adapting a plan and starting over.

Can you change one of our floor plans?
Yes. You can modify layouts and features to fit the way you live, and you are not limited to one of our plans. If you want something unique, we design a custom plan around your homesite, lifestyle, priorities, and design vision.
Our custom home floor plans come in three collections. Gold is warm, timeless, and richly layered. Noir is bold, with clean geometry and dramatic contrast. Luxe is relaxed and shaped around indoor-outdoor living. The construction standard is the same across all three. Each plan is a complete design, which is why adapting one is usually the more efficient path when it already solves most of what you want.
Which changes are simple, and which are not?
How much practical flexibility a plan has depends on what you want to change. We sort changes into three levels.
| Level | Examples | What it involves | Effect on the schedule |
|---|---|---|---|
| Simple | Interior room configurations, kitchen and primary suite layouts, ceiling details, architectural features, finishes, indoor-outdoor connections inside the footprint | Design work and selections, with small drawing revisions | Very little |
| Substantial | The footprint, the structural system, roof geometry, the foundation, major openings, stairs or an elevator, anything that changes the engineering | New architectural work, engineering, estimating, structural revisions, and updated permit documents | Adds time, because pricing, selections, and approvals are revisited |
| Custom | The footprint, circulation, architecture, major room relationships, elevations, structural design, or the overall concept substantially recreated | A custom design around your goals from the beginning | The full design phase, then engineering |
The earlier the level of customization is defined, the easier it is to coordinate design, engineering, estimating, and construction.
What do clients change most often?
The most common theme is a plan that better reflects how the client lives. That usually means kitchens, primary suites, storage, flexible rooms, garages, and indoor-outdoor living, not only finishes. Buyers also expect rooms to serve more than one purpose: bonus rooms, home offices, guest areas, and entertainment spaces.
Reconfiguring interior rooms or suites. Expanding or modifying the garage. Changing ceiling details, architectural features, kitchen layouts, primary suite layouts, or indoor-outdoor connections.
Wet bars, bonus spaces, upgraded kitchens, expanded outdoor living, balconies, and specialized rooms.
Does changing a plan add cost and time?
Yes. Every change has a cost, even one that seems small. Some changes affect only the design or the selections. Others need new architectural work, engineering, estimating, structural revisions, or updates to the permit documents.
Timing matters as much as the change itself. We have had clients reach the pre-permitting stage and decide to change the entire floor plan. It can be done, but the further the project has progressed, the more work has to be redone and the larger the cost. A minor interior adjustment has very little effect on the schedule. A major redesign can add significant time, because plans, engineering, pricing, selections, and approvals may all need to be revisited.
We do not tell clients they cannot make changes. We make sure they understand the cost and the schedule effect before moving forward with them.
The three changes that raise a budget most, in our experience, are adding size or structure, upgrading cabinetry, appliances, and stone, and expanding outdoor living. Our guide to planning a custom home budget covers each one.
When does it become a custom home?
When your needs can no longer be met efficiently by modifying an existing plan. If the footprint, circulation, architecture, major room relationships, elevations, structural design, or overall concept is being substantially recreated, it makes more sense to design around your goals from the beginning.
The question is not how many changes are allowed. It is whether we are still adapting the plan, or forcing it to become something it was never meant to be. If one of our plans gets you 80 to 90 percent of the way there and the remaining changes make sense, adapting it is the efficient path. If you are forcing major changes to make the plan fit your life, we would rather start from scratch. The goal is not to make you fit the floor plan. The floor plan should fit you.
“If your number one priority is getting into a home as quickly as possible, or getting the absolute lowest price per square foot, a fully custom home probably isn’t the right product for you. Sometimes I will tell someone that one of our existing homes or established floor plans makes more sense for them, and I’m completely comfortable doing that.”
Derrick Henderson, President
The same is true in the other direction. If an existing plan does not support how you live, entertain, work, host family, or use the home day to day, it is not the right plan just because it already exists. See custom homes in Naples for how a design from scratch runs.
Adapt a plan or start from scratch? The seven questions we ask
These are the questions we go through with every client who is choosing between the two paths.
- Does an existing plan already solve most of what you want?
- What are your non-negotiables?
- How many major changes are required?
- Is the architecture itself what you want?
- Does the plan work correctly on your homesite?
- How important is complete uniqueness?
- What is your budget and timeline?
Three or more major changes, or a no on questions 1, 4, or 5, usually point toward a custom design. A yes on most of them points toward adapting the plan.
How do you read a floor plan’s square footage?
Every plan lists two numbers: the living area, which is the air-conditioned space, and the total area, which adds the entry, the garage, and the veranda. Three of our plans show how far apart the two can be.
| Plan | Collection | Living area | Total area | Layout |
|---|---|---|---|---|
| The Capri | Gold | 1,601 sq ft | 2,316 sq ft | 3 bedrooms, 2 bathrooms, private office |
| The Amalfi | Noir | 2,275 sq ft | 3,140 sq ft | 4 bedrooms, 3 bathrooms, entertainment lounge and wet bar |
| The Sterling | Luxe | 3,300 sq ft | 4,954 sq ft | 4 bedrooms, 4.5 bathrooms, den, 3-car garage |
When you compare plans, or compare builders on price per square foot, check which number is being used. The garage and the veranda are in one and not in the other. Our guide to choosing a custom home builder covers the other things to line up before you compare two numbers.
Does the plan fit your lot?
A plan and a homesite are decided together. The lot’s orientation, setbacks, required elevation, and views decide whether a plan works as drawn, needs to be mirrored or shifted, or needs a different plan. If you already own the lot, we start there. If you are still looking, we help you evaluate land with the plans you like in mind. Our guide to building on your own lot lists the fourteen things to check, including how much of the lot the setbacks leave you.
Where does the floor plan sit in the schedule?
Floor plan design takes 2 to 3 weeks on a typical custom home, whether we adapt one of our plans or start from a blank page. Engineering and architectural development follow and take 6 to 8 weeks. Selections run alongside both. Decisions about the plan belong in those first weeks: after the engineering is done, every change to the footprint or the structure reopens it. Our guide to how long it takes to build a custom home in Florida shows the full calendar.
Frequently asked questions
Can a floor plan be modified?
Yes. Every plan in our collections is a starting point. Interior rooms, suites, kitchens, ceiling details, architectural features, and indoor-outdoor connections are changed regularly. Changes to the footprint, structure, roof geometry, foundation, major openings, or stairs need more substantial redesign, and we tell you which is which before you commit.
Does customizing a floor plan cost more?
Every change has a cost, even a small one. Some changes affect only the design or the selections. Others need new architectural work, engineering, estimating, structural revisions, or updated permit documents. We price the change before you decide, so the cost and the schedule effect are known in advance.
How long does it take to customize a floor plan?
Floor plan design takes 2 to 3 weeks on a typical custom home, followed by 6 to 8 weeks of engineering and architectural development. A minor interior adjustment has very little effect on that schedule. A major redesign adds time, because plans, engineering, pricing, selections, and approvals may all need to be revisited.
Can I make one of your plans bigger?
Yes, and it is one of the changes clients ask for most. Adding square footage or expanding the garage is a substantial change: it affects the foundation, framing, roof, mechanical systems, engineering, and finishes, not only the added space. The earlier it is decided, the less work has to be redone.
Can I build a plan exactly as drawn?
Yes, with the adjustments every homesite needs: orientation, setbacks, required elevation, and views. If you already own the lot, we start there. If you are still looking, we help you evaluate land with the plans you like in mind.
Can I bring my own plan?
Yes. Plans drawn without a builder at the table often need revision for cost, constructability, and the Florida Building Code, so we review them before pricing. If your plan is close to one of ours, adapting ours may be the faster path.
When should I decide on the changes I want?
As early as possible, and before engineering starts. The earlier the level of customization is defined, the easier it is to coordinate design, engineering, estimating, and construction. Changes made after the permit documents are drawn cost the most in time.
Before you choose a plan
Start with how you live, not with square footage. Pick the plan that gets you 80 to 90 percent of the way there, list the changes you need, and sort them into simple and substantial. Decide the substantial ones before engineering starts. If the list is long, or the architecture is not what you want, a custom design is the better path, and we will say so.
