Superficially a Manhattan residential building, 35XV would be a classic podium-and-tower condo but for the fact that the podium doubles as an addition to the local high school. In return for this community investment, developer Alchemy Properties received partial air rights above the original school, which sits on an adjacent lot.

The condo tower is a leaf-shaped polyhedron that cantilevers outward from its base, enabling local firm FXFOWLE to increase the interior space by 40 per cent. The high school podium – a granite box with a chiseled facade – complements its Flatiron District neighbours, while the tower’s reflective fish-scale glass merges with the sky above.
