Tankhouse is a Brooklyn-based real estate development firm. Our team brings together expertise in architecture, urban design, finance, construction, management, and education.

Sam Alison-Mayne and Sebastian Mendez met on the Sperone Westwater Gallery, Sam as construction manager for Sciame and Sebastian as an architect at Foster + Partners. They founded Tankhouse in 2013, convinced that New York needed a developer willing to rethink housing.
