Roof and Realm

Roof and Realm is a California-based prefab home builder specializing in steel-framed modular residences and accessory dwelling units, positioning itself as the only home builder to construct steel-framed ADUs. Based in Concord, the company offers five distinct product series — Realm X for ADUs, and Realm Y, Z, M, and C for a range of single-story and two-story residential configurations — providing a broad selection of sizes from compact ADUs to larger multi-bedroom homes. All structures use steel frames combined with spray foam insulation and fire-retardant components, with approximately 98% recyclable material content, making them highly resistant to earthquakes, fire, wind, and termites. Roof and Realm delivers turnkey, solar-ready or solar-included homes from design through installation with a streamlined six-to-eight-month timeline, serving California homeowners and offering nationwide design consultation.
