Expert Accessory Building Construction in Cary, NC

Accessory building construction adds usable space to your property without touching your main home. At Firm Foundations Homebuilders, we build detached garages, workshops, storage buildings, and backyard studios for homeowners in Cary and the surrounding Triangle area. Erik's background in architecture and home inspection means every structure is planned with an eye for how it fits the property, meets local setback rules, and holds up over time. In Cary, accessory structures must stay within size limits tied to your home's square footage, and any structure over 12 feet in any dimension requires a building permit. We account for those requirements from the start, so your project moves forward without surprises. Whether you need a place to park vehicles, run a home-based workshop, or store equipment, we design and build a structure that serves your specific needs. Call us to talk through your project.
