Transform Your Garage Into Livable Space
Whether you need a home office, rental unit, or extra living space, Prolific Design-Build converts garages into fully permitted, code-compliant living areas throughout King County. Our design-build process handles everything from architectural plans and permit applications to framing, electrical, plumbing, insulation, and finish work.
Why Convert Your Garage?
Garage conversions are one of the most cost-effective ways to add square footage to your home. With King County property values continuing to rise, converting an unused garage into a finished living space can increase your home value by 20-30% of the conversion cost while creating the functional space your family needs today.
Our Garage Conversion Services
We handle every phase of the project: structural engineering assessments, permit drawings, foundation and floor leveling, insulation to meet energy code, electrical panel upgrades, plumbing rough-in for bathrooms or kitchenettes, drywall, flooring, and all finish details. Every project is fully permitted and inspected.
ADU and DADU Conversions
Detached garage conversions may qualify as Detached Accessory Dwelling Units (DADUs) under current King County and Seattle zoning. We navigate the ADU permitting process and ensure your conversion meets all setback, parking, and building code requirements for legal occupancy.
Service Area
We serve homeowners in Seattle, Bellevue, Kirkland, Redmond, Issaquah, Sammamish, Woodinville, Bothell, Kenmore, and throughout King County.
