The 3D Housing Grid project is located on West 128 Street at Lenox Avenue in Harlem. It tackles the pressing need for affordable housing in a neighborhood known for its rich history and diverse community but also marked by many vacant lots. The design blends new residential units with the existing built environment, aiming to serve various housing needs while avoiding displacement of current residents. The project features both luxury and affordable housing units, creating a balanced solution aimed at bringing life back to the area.

ARCHITECTURAL CONCEPT

The core idea of the design is a low-rise, high-density housing model that works well within the local context. It takes advantage of three existing townhouses and four vacant lots, introducing two new ground-level units. Above this base, a concrete super-structure supports additional residential spaces. This layered design connects new buildings to what is already there, showing a thoughtful approach to urban growth.

FINANCIAL SUSTAINABILITY

A key aspect of the design is its dual-layered housing strategy. Luxury townhouses are built on the upper levels to generate revenue. This income helps to fund the construction of affordable units on the ground level. By connecting luxurious living with affordable options, the project creates a way to ensure long-term financial health while addressing immediate housing needs in the community.

COMMUNITY INTEGRATION

The design focuses on community engagement by including shared gardens at the back of the development. These green spaces act as places where residents can come together and interact. They not only brighten the environment but also provide essential areas for socializing. The layout promotes easy access, with elevators and stairs positioned to serve residents effectively, ensuring that navigating the space is straightforward for everyone.

DESIGN DETAILS

The overall shape and arrangement of the buildings contribute significantly to the project’s intention. It presents a mix of solid forms and open areas that reflect the character of the neighborhood. Terraces function as smoke balconies, addressing fire safety while contributing to the building’s design. This thoughtful arrangement shows a commitment to respecting the area’s heritage while meeting modern living standards. Such design efforts highlight the balance between celebrating the past and accommodating contemporary housing needs.
