A townhouse and carriage house were converted to provide a headquarters for a real estate developer and a nonprofit education foundation as well as incubator space for like-minded start-ups. The renovation creates an office community that allows tenants to share resources and amenities. Inside, the lobby, conference rooms, library and kitchen share a modern design of artisan-crafted metal and sleek millwork. All non-original ornament and trim were removed to reinstate historic integrity. Non-essential partitions were replaced with translucent glass panels to connect work areas that introduce daylight to the interiors. New HVAC, electrical, plumbing, fire and life safety systems provide improved capacity for intensified use and ensure energy efficiency.
