Types of Home Additions We Build

Room Additions

Expand your footprint with a seamlessly integrated bedroom, living room, or family room addition that matches your existing home's style and structure.

ADU / Granny Flats

Add a fully independent accessory dwelling unit to your property — perfect for aging parents, adult children, or rental income.

Garage Conversions

Transform an underused garage into a functional living space: home office, studio, gym, or guest suite.

Sunrooms & Enclosures

Bring the outdoors in with a bright, energy-efficient sunroom or screened enclosure — ideal for Florida's climate.

Second-Story Additions

Double your square footage without sacrificing yard space with a structurally engineered second-story addition.

Covered Patios & Outdoor Living

Extend your living area outdoors with a custom covered patio, pergola, or outdoor kitchen built to Florida code.
