Founded in 1988 by Frank and Tricia Sinn, Sinn Design • Build has quickly earned a reputation for inspired designs with impeccable quality and attention to detail. Based in Ladue, Sinn provides custom home building and renovations, all of which begins with a Sinn Design • Build exclusive Design Assessment - a comprehensive assessment of needs, wants and budget before design ever begins. This ensures the perfect reflection of the homeowner's lifestyle and goals in the finished product – all within budget.

Sinn is well known for bringing innovative techniques, materials and designs to the St. Louis area. Sinn's latest development, The Cottages of Ladue at Dwyer Place, features the first authentic cottage homes to be introduced to St. Louis.

Sinn homes can be found throughout West St. Louis County and the Highway 40 central corridor in Ladue, Frontenac, Clayton, and Town & Country.
