Boutique studio. Big Impact.

From our Soho office, Kostow Greenwood Architects brings precision, agility, and care to complex architectural challenges from historic theaters and cultural institutions to nonprofit headquarters and new ground-up buildings.

With decades of experience and a passion for craft, we deliver work that exceeds expectations. We combine technical excellence with human-centered design to create places where creativity, comfort, and community thrive.

Rooted in curiosity and driven by quality, we approach every project with the belief that great design emerges through deep listening, meaningful collaboration, and a commitment to making space for people to do their best work.

St. Ann’s Warehouse has consistently had great experiences working with KGA on multiple projects every season. Our artists constantly push the boundaries of our flexible space and the physical relationship between performers and audience. KGA is essential in helping us take on the wildest artistic ideas and turn them into safe, code-compliant projects. They are excellent at balancing artistic vision with audience safety and are always enthusiastic about exploring creative solutions.
