Working with New York firm, General Assembly, we oversaw a multi-year full renovation of this 200 year old rowhouse in the historic district of Philadelphia's Fitler Square neighborhood. 

Our clients — a young couple with a growing family — were drawn to the house for its wonderful location, but its bones and plan required attention. The project involved an exhaustive interior demolition process, reinforcing the existing exterior walls and floors, replacing windows, vaulting ceilings, adding skylights, installing new framing, flooring and finishes. New built-in millwork and furnishings help to maximize every square inch of the narrow footprint of this 1,750 sf house. 

The most difficult and meaningful part of the renovation was the addition of a glass Dining Room off the back of the kitchen. This 75 square foot thermally-broken steel and glass room also functions as the new main entrance into the house.
