Established in 1990, the office of Dirk Denison Architects offers a full range of programming, site analysis, design, preparation and administration of construction documents, and post-construction analysis, as well as interior furnishing and furniture design. Best known for its award-winning residential work, the Chicago-based firm has built its reputation of design excellence through a wide range of projects and scales, including multi-family, institutional and commercial projects.

Dirk Denison Architects believes in the power of architecture to construct experience. The firm’s work focuses on creating a narrative that combines the idiosyncrasies of site, program and, ultimately, architecture. It is a process that elicits surprise, revelation, information, poetry, and seduction while fulfilling a basic human desire to shape its surroundings. The success of DDA’s work has led to a continued relationship with many of its clients on both a professional and personal level, testaments to the meaningful experiences that the firm’s creations engender.
