More room on the island without moving — additions designed to match your home and engineered for coastal code. Suites, second stories, and outdoor living. Free consult.
Same-day response, Mon–Sat. No cost, no obligation.
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.
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.
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.
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.

More room, seamlessly added, coastal-code correct.
Added a primary suite with a water view that looks like it was always part of the house. They handled the elevation rules without a hitch.
Second story gave us two bedrooms and a deck without losing the yard. Engineered for the wind zone and rock solid.
Built a guest suite for visiting family — private, beautiful, fully permitted, and built to coastal code. Smooth process start to finish.

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.
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.
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.
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.
