Tankhouse is a Brooklyn-based real estate development firm with over 30 years of collective experience in architecture, urban planning, development, and construction. Formed in 2013 by partners Sam Alison-Mayne and Sebastian Mendez, Tankhouse was built on the belief that design and development are symbiotic disciplines, and the best results emerge from an integrated and holistic approach.

Tankhouse develops projects in Brooklyn, where they live and work. By prioritizing shared spaces that reinforce community, thoughtfully considering the journey from street to doorstep, and offering abundant private outdoor spaces, Tankhouse has quickly defined a niche for themselves in an incredibly competitive industry.

Experimental with architectural forms, materiality, and layouts, the team is always rethinking ways to improve quality of life and turn route apartment living into singular homes. For every project, Tankhouse curates a team of like-minded talents who push one another to find the optimal design solution for each unique location.

Tankhouse purposefully chooses challenging and unexpected sites to develop, and considers the unique qualities of each to find a solution that fits within the context of the surrounding built environment. In addition to Nine Chapel, projects include: 450 Warren Street, 144 Vanderbilt Avenue, and 450 Union Street. 450 Warren Street, the company’s first completed development, is located in the heart of Brooklyn’s Boerum Hill neighborhood. The 52,479-square-foot residential building offers a new paradigm for dense urban living. This first collaboration with architects SO-IL resulted in a design that demonstrates both parties’ philosophies and approaches to simultaneously facilitating intimacy and community. Arranged around a trio of voids carved from the structural volume, the 18 residences all enjoy multiple orientations, and are connected by outdoor corridors, bridges and stairs.

450 Warren Street has since sold-out and received critical acclaim in The New York Times, Fast Company, Architectural Digest, and Architectural Record. Along with Nine Chapel, Tankhouse is also currently working on a residential and retail development at 144 Vanderbilt Avenue in Fort Greene, slated for completion in 2024, and another at 450 Union Street in Gowanus.

144 Vanderbilt's precast concrete facade is currently rising at the corner of Vanderbilt Avenue and Myrtle Avenue. The project's 26 units, ranging from two to four bedrooms, capitalize on the site's corner condition to produce homes with multiple exposures, exterior space, shared gardens, and premium amenities. Sales are slated to begin Summer 2024, with project completion Winter 2024.
