Founded in 1992, WJArchitects (WJA) is an interdisciplinary architecture firm that creates engaging spaces for working, living, learning and playing. The firm’s design methodology is centered on the belief that architecture can inspire positive change and enrich society. With each project and any given set of challenges, we strive to provide creative design solutions that promote community and client ambitions, redefine conventions, and generate purpose driven solutions. 


WJA’s capabilities expand beyond architecture to include interior design, development, and design-build construction. As one of the few architecture firms with a dedicated construction division we are able to provide comprehensive pre-construction planning including feasibility & land acquisition studies, cost estimating and constructability reviews all in house.
