Island lots are precious, and moving means giving up your spot on the water. An addition lets you stay and gain the space you need — a primary suite, a second story for more bedrooms, or the indoor-outdoor living the Gulf lifestyle is made for. On the barrier islands, additions also mean coastal engineering and flood-zone rules, which is exactly where our design-build expertise pays off.

Coastal Additions We Build

Matched to Your Home, Engineered for the Coast

A great addition looks original — matching rooflines, materials, and floor levels so the new space flows from the old. On the islands, it also has to satisfy wind-load, elevation, and flood requirements. We design for both: a seamless look and the coastal engineering that keeps it solid, compliant, and insurable.

Adding in a flood zone? New square footage and substantial additions can carry elevation and code requirements. We plan for them from day one so your addition is compliant and protected.

What a Coastal Addition Costs

Additions are priced by size, complexity, and the structural, elevation, and systems work the tie-in requires — a simple room addition differs greatly from a second story on a coastal foundation. We assess your home and goals, give you a real budget before design, then build to it.

One Coordinated Team

Design, engineering, permitting, and construction under one roof means your addition is planned correctly from the start — no gap between architect and builder where coastal details, budgets, and timelines slip.

Frequently Asked Questions

How much does a home addition cost on Treasure Island?

Additions are priced by size, complexity, and the structural, elevation, and systems work involved — a room addition differs greatly from a second story on a coastal foundation. We assess your home, give a real budget before design, then build to it. Call (727) 349-5715.

Can I add a second story on a coastal home?

Often yes, depending on your existing foundation and structure, which we evaluate first. On tight island lots a second story is frequently the smartest way to gain bedrooms without losing outdoor space — engineered to coastal wind code.

Will an addition trigger flood-zone or elevation rules?

It can — new square footage and substantial additions may carry elevation and code requirements in coastal flood zones. We know the thresholds and plan your addition to be compliant and protected from the start.

Will the addition match my existing home?

Yes — we match rooflines, materials, window styles, and floor levels and design the connection so the new space looks original, while meeting coastal engineering requirements.

Do you handle engineering and permits?

Yes — coastal additions involve foundations, structural tie-ins, wind-load engineering, and flood-zone rules. As a design-build firm we engineer, permit, and build it correctly and compliantly.
