David Reeve Photography; The "four-square" is a common house type found in the DC area, characterized by an efficient but generous floor plan and minimal circulation. This home had already been renovated, but a new family with three children needed more space. By surrounding the existing rooms with a family room (to the side) and kitchen/breakfast room (to the rear), the space needs were met, while still maintaining logical movement through the house. A critical element of the work was the creation of a large Mudroom/Pantry, as well as a "command center" on the new back hallway. A Master Bedroom suite occupies the second floor addition and a large shed dormer at the rear provides a bedroom for two brothers. At the basement, new recreation space drops 18" below the existing level, with a large window well at the front providing southern light.
