More Space, More Comfort, Same Address

Home additions are the perfect solution for growing families, aging-in-place upgrades, or simply enhancing your lifestyle. We manage the entire process—from design and permitting to construction and finishing touches—ensuring the new space blends perfectly with the existing structure.

Common Home Additions We Build:

  • Bedroom and guest suite additions
  • Second-story expansions
  • Kitchen and dining area extensions
  • Garage conversions and ADUs (accessory dwelling units)
  • Home offices and multi-purpose rooms

Seamless Integration with Coastal Construction Standards

We don’t just build out—we build smart. Additions are planned to comply with Key West zoning, environmental, and hurricane codes, ensuring safety and longevity.



  • Flood-zone elevation and drainage planning
  • Wind-rated roofing and siding
  • Impact windows and sealed entry points
  • Materials resistant to humidity and corrosion

Your new space will feel like it was always part of the original home—just stronger.

Our Home Addition Process

Step 1 – Consultation

We discuss your space needs, budget, and ideal layout. We measure, inspect the property, and offer ideas that match your home’s footprint.

Step 2 – Design & Planning

Whether you're working with your own designer or we provide one for you, we handle the planning, permits, and timeline to keep your project on track from start to finish.

Step 3 – Construction

We begin with excavation or structural modification, then build walls, install systems, and complete the finish work.

Step 4 – Final Integration

We match roofing, paint, flooring, and trim so the addition is indistinguishable from the original structure.
