Accessory buildings put real structures on your land — detached garages, workshops, studios, and storage barns built with foundations, framing, and utilities, not bolted-together kits. The value is in doing it as construction: a slab and structure engineered for what the building holds, power and access planned up front, and county permitting handled like any other permanent building.

Projects are scope-first — a two-car garage and a wired workshop are different animals — so pricing follows a site visit. Mabrey Construction designs and builds them under one fixed-scope contract.
Setbacks, size limits, and access get confirmed for your lot first, so the building you design is the building you can build.
A car barn, a woodshop, and a studio have different slabs, doors, power, and ventilation — the design starts with what goes inside.
Foundation to final inspection runs on a written schedule, and the building is ready to work the day we hand it over.
- Detached garages sized for vehicles, lifts, and actual storage
- Workshops and studios with power, lighting, and ventilation planned in
- Storage buildings and barns framed for decades, not seasons
- Slabs and foundations engineered for the loads the building will carry
- Electrical service runs, sub-panels, and outlets where work happens
- Doors, access, and driveway connections designed for how you use it
- Zoning, setback, and size review for your parcel before design
- Durham, Wake & Orange permitting and inspections in the fixed scope

These projects are scope-first: size, slab, doors, power, and finish level move the number more than any rule of thumb, so we price after a site visit rather than guessing in a range. You get a fixed, itemized figure in writing before anything breaks ground.
Permanent structures with foundations and electrical are permitted, inspected construction in North Carolina, and each county sets size and setback rules for accessory buildings. We confirm your parcel's rules first and run the permitting inside the scope.
Yes — siding, roofing, trim, and proportions can be matched so the building reads as part of the property rather than an afterthought. It is a finish-level choice we price alongside the practical options.
Most accessory buildings run six to twelve weeks of construction once permits are in hand, driven by size and finish level. The written schedule comes with the contract, and site disruption stays planned rather than surprising.
