Florida House Plans, Designed for Your Lot

Every home we design starts as a concept like these. Pick a plan and a style, send us your lot, and we design the house and engineer the structure for wind and flood in one set for permit. Each home is drawn for its own survey, flood zone and wind exposure. Fully remote.

How It Works

From your lot to a permit set

1. Send the lot. We need the survey, plus the flood zone if you have it, and a short wish list. Or take the Custom House Design quiz below.

2. Pick a direction. Start from a concept home and a style, or from your own sketch.

3. We design and engineer it. You get the floor plans and elevations, plus the foundation, framing and wind and flood design, in one coordinated set for permit.

Questions

Can I buy one of these plans as-is?
No. These are concept designs, not construction plans. Every house is fitted to its own lot, setbacks, flood elevation and wind exposure, then engineered. That is the work we do.

Are your Florida house plans engineered and sealed?
Yes. The permit set includes the structure, sealed by a Florida PE: the foundation, the framing, and the wind and flood design.

Can you change the plan?
Yes. The concept is a starting point. Rooms, sizes, the garage, the style and the number of stories all change to suit the lot and the wish list.

Which plan fits a narrow beach lot?
The Beach House on Pilings is drawn for a 50-foot-wide lot. The Bayfront House fits a narrow, deep waterfront lot with the garage underneath.

Concept designs, not for construction. Plans and images are for illustration. Every home is designed and engineered for its own lot, flood zone and wind exposure; the builder confirms field conditions.
