Home Additions in Longboat Key

Southpaw Remodeling plans and builds attached and detached additions throughout Longboat Key, managing permits, structural coordination, and construction as one unified scope. Chris and Danielle Lisinski work directly with homeowners to create additions that match the existing structure and serve a clear purpose.

Every addition we build on Longboat Key is designed for the coastal environment. Materials, connection points, and finishes are selected with Gulf Coast humidity, wind loads, and salt air in mind from the start.

Attached Room
Additions

We build attached additions to Longboat Key homes that expand the footprint and connect directly to the existing structure. New rooms are matched to the roofline, exterior cladding, and interior finishes so the addition reads as part of the original home.

Common attached additions include primary suites, expanded living areas, family rooms, and home offices. The structural connection is designed carefully so the transition is clean and the building envelope stays intact.

Detached Guest Houses and Studios

We build freestanding structures on Longboat Key properties for use as guest suites, home offices, artist studios, or caretaker quarters. Detached additions give you usable space without affecting the flow or privacy of your main living area.

Every detached structure is built to the same standard as the primary home, with full mechanical, electrical, and plumbing where the use requires it.

Screened Lanai and Outdoor Living Additions

We design and build screened lanais and outdoor living spaces for Longboat Key homeowners who want to spend more time outside. The right lanai extends your usable square footage without sacrificing the Gulf views and coastal air that make the island worth living on.

Lanai additions are engineered and permitted to Florida code and built to hold up to Gulf wind, rain, and salt exposure year after year.

Garage and Carport Additions

We build attached and detached garages and carports across Longboat Key that protect vehicles, provide storage, and add long-term value to your property. Every structure is permitted, engineered for Florida wind loads, and finished to match your home’s exterior.

Garage additions can be freestanding structures or integrated directly into the home with interior access, depending on your site and your goals.

Second-Story Additions

We build second-story additions on Longboat Key homes when expanding outward is not an option. A second floor unlocks space for bedrooms, bathrooms, or living areas without changing the property boundary or reducing your outdoor footprint.

Second-story additions require structural engineering and permitting. We manage both from the start and coordinate them with the full construction schedule.

Permitting and Structural Engineering in Longboat Key, FL

Every home addition in Longboat Key requires proper permitting and structural review before a single framing nail goes in. We manage the full permitting process and coordinate with qualified engineers to ensure your addition meets Florida building codes and local requirements.

You do not have to navigate Longboat Key’s permitting process on your own. We handle it as part of the project scope.

What Our Home Addition Services Include

We design every Longboat Key home addition around your property’s existing structure, your intended use, and your long-term goals. No off-the-shelf plans. Every addition starts with a site visit and a direct conversation about what you actually need from the space.

We source framing, roofing, siding, windows, and interior finishes from suppliers built for the Florida climate. Your addition is constructed to hold up against Gulf Coast weather, salt air, and coastal humidity for the long term.

Our team oversees every phase of your addition from permitting through the final walkthrough. You receive real-time updates through Buildertrend, and the project moves on a schedule that minimizes disruption to your household throughout construction.
