An addition is part new construction and part renovation. The new structure has to meet today's code while connecting to a house that may have been built decades ago. We start by checking what your lot allows — setbacks, lot coverage, flood rules — and what the existing structure can carry, so the design is buildable before you pay for full drawings.

What's included

  • Ground-floor additions

    Bedrooms, family rooms and primary suites on new foundations tied to the existing home.

  • Second-story additions

    Upper floors where the existing walls and foundation can be engineered to carry the load.

  • Garages & conversions

    New garages, carports, or converting an existing garage into finished living space.

  • Covered outdoor rooms

    Roofed patios, summer kitchens and screened rooms that are permitted and built to wind code.

  • Mechanical tie-ins

    Extending or upsizing HVAC, electrical service and plumbing to serve the new space.

  • Seamless finishes

    Rooflines, stucco, flooring and trim matched so the addition looks like it was always there.

How the project runs

  1. 01

    Feasibility check

    Survey, zoning setbacks, flood zone and a look at the existing structure to confirm what can be built.

  2. 02

    Design & engineering

    Drawings and structural engineering prepared and reviewed for cost before permit submission.

  3. 03

    Permit & build

    Permit approval, then foundation, structure, dry-in and tie-in to the existing house.

  4. 04

    Finish & final

    Interior finishes, final inspections and closeout of the permit.

Before you plan an addition

Setbacks & lot coverage
Local zoning limits how close you can build to property lines and how much of the lot can be covered.
The 50% flood rule
In flood zones, if improvement costs reach half the home's market value, the whole house may need to meet current flood standards.
Living at home during work
We plan dust control, access and the timing of the tie-in so the house stays livable as long as possible.

FAQ

Home Additions: common questions

Can my house support a second story?

Sometimes. A structural engineer has to evaluate the existing foundation and walls. We arrange that review early so you know before investing in full design.

Do home additions need a permit in Florida?

Yes. Additions require a building permit with drawings, and usually separate electrical, plumbing and mechanical permits. We handle all of them.

Will the addition match my house?

That is the goal from the first drawing. We match roof pitch, stucco texture, window style and interior finishes so the addition reads as part of the original home.
