Dean Street Townhouse
2 Family Residence
Architect, New Construction

Set on a narrow 17’-6” wide lot in Brooklyn, this new four-story + cellar residence replaces a deteriorating wood-frame structure with a modern, energy-efficient two-family home. Designed to maximize every inch of its compact footprint, the project demonstrates how thoughtful design and high-performance construction can unlock the potential of even the most constrained urban sites.

The building is organized with a ground floor in-law suite, while the upper three floors comprise the primary residence. A bay window extension at the front not only expands the interior space within zoning limits but also opens up long views down the block, creating a stronger connection to the street and neighborhood.

Vertical circulation is centered around a generous open stairwell topped with a skylight, bringing natural light deep into the home and enhancing the sense of openness despite the site's narrow dimensions. Outdoor space is integral to the design, with a rear deck off the main living floor and two private roof decks that extend the living experience beyond the walls.

The project incorporates Passive House principles to ensure long-term energy performance and comfort. A fiber cement rainscreen system with mineral wool insulation forms a high-performance envelope that exceeds energy code requirements. High-efficiency Schüco windows, continuous air sealing, and a heat recovery ventilation (HRV) system ensure optimal indoor air quality and minimal energy use throughout the year.

This residence is a testament to how tight urban conditions can inspire highly tailored, sustainable solutions—bringing together livability, resilience, and architectural clarity on a modest footprint.
