Custom Plans in Florida

Stock plans are cheap and usually wrong, because they were drawn for a different lot in a different climate. We draw to your parcel: how the building sits for afternoon sun and prevailing breeze, where the shop door faces, how the porch handles Florida rain. Plans come engineered and permit-ready.

How a custom plans project runs

Four stages, in this order. The sequence matters more than it looks: getting engineering and permitting settled before anything is fabricated is what keeps a build from stalling.

1

Program and site visit

We list what the building has to do: bedroom count, shop bays, RV height, covered porch, future expansion. Then we look at the actual land, because slope and access change layouts.

2

Concept layouts

You get two or three floor plan concepts with elevations. We expect you to mark them up. Most projects go through two rounds before something clicks.

3

Construction documents

The chosen concept becomes a full permit set: floor plans, elevations, sections, foundation plan, framing, and electrical layout.

4

Engineering and stamp

A Florida-registered engineer reviews and stamps the set for your county wind load. You own the drawings and can build them with us or anyone else.

Drawn to your land

A stock plan is cheap because it was drawn for someone else

Downloadable barndominium plans are usually drawn for a different climate, a different code, and a flat rectangular lot that is not yours. In Florida they get rejected at plan review for missing wind criteria, and even when they pass, they ignore how your building should sit for afternoon sun, prevailing breeze, and where the water goes in August.

Before you commit

What actually decides the price

Square footage is the number everyone leads with, and it is rarely the one that moves a barndominium budget. These four do.

  • Size and complexity

    A simple rectangle with a porch draws quickly. Wings, changes in roof plane, and mezzanines multiply the number of sections and details a permit set needs.

  • Revision rounds

    Two rounds are normal and included. Endless redesign after construction documents have started is what turns a fixed fee into an hourly one.

  • How far the set goes

    Concept layouts alone cost a fraction of a sealed permit set. Deciding up front which you are buying avoids paying for drawings you cannot build from.

  • Site specifics

    Slope, flood elevation, wetlands setbacks or a lakefront high water line all add site work to the drawing set that a flat inland lot does not need.

Custom Plans in Florida: common questions

5 questions we get asked most often about building in Florida. If yours is not on the list, ask it directly.

Start your project
Do I own the plans when you are finished?
Yes. You pay for them, you own them, and you can build them with us or with anyone else. We say this plainly because some designers licence plans for a single use and it is not always obvious until you try to take them elsewhere. If you build with someone else we will still answer an engineer question for your reviewer.
Can I bring a plan I found online and have you adapt it?
Often, yes, and it is a reasonable way to save money if the layout genuinely suits you. What we cannot do is stamp someone else drawings unchanged, and that is a legal constraint rather than a policy one: an engineer seals a design they are responsible for, and a set drawn for another state was not engineered for your wind speed. Adapting means redrawing the structure to Florida code and your parcel criteria, which is most of the work. If the plan needs heavy modification you can end up paying more than a clean sheet would have cost, and we will tell you when that is the case. Why Florida requires this at all.
How many revisions do I get?
Two rounds on the concept layouts, which is where the real decisions get made, and we expect you to use them. Most projects change meaningfully between the first and second round: a shop bay grows, a bedroom moves off the west wall, the porch gets deeper. Changes after construction documents begin are quoted separately, because at that point every sheet has to be redrawn.
Do the plans include the engineering stamp?
Yes, and for this building type it is not optional. A conventional stick-built house can often be permitted off the code prescriptive tables without an engineer, which is why people assume the same applies here. A clear-span or post-frame structure sits outside those tables by definition, so the code requires an engineered design. The set includes floor plans, elevations, sections, the foundation plan, framing, and electrical layout, sealed by a Florida-registered engineer for your parcel wind criteria.
How long does the drawing process take?
Concept layouts come back within a couple of weeks of the site visit. From your chosen concept to a sealed permit set is several weeks more, depending on complexity and how quickly you turn around markups. The stage that most often stalls is not our drawing time, it is waiting on a survey or a soils report, so we ask you to order both early.
