Square One Development Group brings DC- and Bethesda-level architect-led residential construction to Frederick, MD — for historic neighborhoods, estate properties, and serious renovations that deserve a builder of the highest standard.
The caliber of work the city deserves.
Frederick County spans a remarkable range — the historic streets and protected districts of Downtown Frederick and Baker Park, the established character of Braddock Heights and Middletown, and the estate properties of Ijamsville, Urbana, New Market, and Lake Linganore. Each calls for a builder who can move fluidly between sensitive historic work and ambitious new construction, and who treats every site, old or new, with the same rigor.
That is the standard we bring to Frederick: the discipline, craft, and discretion behind award-winning homes in DC, Bethesda, and across the region — now intentionally focused closer to home.
Our homes have earned national AIA honors and International Architecture Awards and been published in Dwell, Interior Design, and Architectural Record. In nearby Bethesda we built Jigsaw, the recipient of a national AIA Institute Honor Award; across the region we’ve built steel-framed homes on demanding sites, board-formed concrete, and whole-house gut renovations. Explore the full portfolio and the record.
Historic and sensitive renovations that honor the architecture; architect-led additions that read as though they were always there; and high-end custom homes on estate and country properties. When the work is done, Square One Care keeps the home performing for years after.
