9 ChapelBrooklynUSA

9 Chapel Street is a residential building in Downtown Brooklyn that stands on a rare freestanding site, open on all four sides. The project explores new models of urban living, with particular focus on connecting indoor and outdoor space, fostering shared and community spaces, and creating apartments defined by qualities beyond size.

Every residence is paired with outdoor space—balconies, terraces, porches, and window gardens extend living areas and invite changing uses across seasons. Outdoor spaces become integral to daily life rather than a penthouse privilege, supporting dining, gardening, reading, and gathering. Screened exterior halls bring daylight and fresh air to circulation areas, transforming corridors into lively stoops that connect neighbors, while an exterior stair provides an additional communal space. Rotations within the plan allow different rooms to capture varied daylight and shifting views across Brooklyn throughout the day and year.

The building’s form shifts as one moves around it, its identity defined less by a fixed profile than by the layered veil of screens that wrap its exterior. These porous surfaces reveal the presence of outdoor rooms and their life, allowing the activities of individual homes to contribute to the collective character of the whole. On its open site, 9 Chapel becomes both a vertical neighborhood and a civic presence, demonstrating how architecture can enrich community through everyday living.
