The Arrowhead A-Frame was designed for a Philadelphia family who wished to optimize its unusual lot geometry: side property lines perpendicular to the waterfront taper slightly inward. In minimizing required setbacks and maximizing buildable area, a unique form was generated that deviates from the typical orthogonal A-Frame footprint. As converging roof planes meet, the ridge drops from front to back, adding additional drama to the upper-level spaces and the termination at the window wall. Exaggerated rake overhangs provide additional shading and weather protection at the front and rear entries and frame views of a large lakeside deck and seating area below. The Arrowhead A-Frame takes some of its design cues from Philadelphia’s rowhome typology: an efficient circulation stack located along the side opens up the floor plan and pierces the roof plane, creating an upper-level outdoor terrace above. Sleeping areas, baths, and an eat-in kitchen are tucked into a tight programmatic core that allows for maximum height and views for the living area facing the double-height lakeside window wall. A 2nd floor ship ladder that mimics the pitch of the roof plane leads to a bonus balcony room at the upper loft level.
