TenBerke Architects

41 Madison Avenue, 17th Floor
New York , New York 10010
Phone: (212) 229-9211

TenBerke is a New York-based architecture studio united by values, bound by the promise that architecture must build toward dignity and decency, that the truest measure of good design is the good that it does the world. And it must be good in these ways: imaginatively, sustainably, delightfully.
We believe that architecture is never an end itself, but a tool that turns what we have into what we need.
We design intentionally; this means work that is not only idealistic, but also effective, navigating a nuanced path between the world as it is and the world as it must be. This is what gives our work its authenticity, complexity, grit, and texture, impactful at first glance and delightful over time.
