An accessory dwelling unit (ADU) is a small, self-contained home built on a property that already has a house — a backyard cottage, in-law suite, or guest house. Triangle Design Build is Chatham County's local ADU expert. We review your lot, handle zoning and permits, and design and build a modern ADU that fits your property and your family.

Why families are building ADUs

Keep an aging parent close while everyone keeps their privacy. Give grown children a place to land. Create a guest house, studio, or future downsizing option — without leaving the property you love.

Designed first, not just built

An ADU should feel like architecture, not a shed. We design modern, light-filled small homes that complement your main house.
