From a national AIA Honor Award to an Olson Kundig house in the Blue Ridge — for decades, the DMV's most celebrated architects have trusted Square One to build their most important work.
Start a ConversationWe build architect-led homes recognized for craft, precision, and restraint — quietly, carefully, and for clients who value discretion.
Hillsides, structural glass, board-formed concrete, geothermal systems, AAC block — the engineering behind the beauty is where the real work lives, and where three decades of craft show. It's the reason architects bring us the details other builders quietly decline.
Also in the portfolio: Blue Ridge House (Olson Kundig), Laverock House, Cumulus House, Blaisdell, Matryoshka & Kalorama.
We engage early, defend the design through preconstruction and value engineering, and execute the details others avoid. Bring us the ambitious work. We'll protect the design, solve the field conditions, and make it real.
How we work →We've built for public figures, private families, and institutions whose names we don't share. Discretion is part of the work.
Whether you're already working with an architect or just beginning to plan, we'll help you understand the path from idea to finished home — across Washington, DC, Maryland, and Virginia.
