144 Vanderbilt Avenue #TH1

Townhouse 1 at 144 Vanderbilt Avenue is the one duplex in the building conceived with Dinesen, the Danish flooring house, and the Copenhagen architect David Thulstrup, now in contract at $3,975,000. Custom Dinesen oak, in the Layers and HeartOak cuts, runs across the floors, walls, and stairs of a double-height duplex with a garden, four bedrooms, and exposed concrete ceilings.

The building is its own event. SO-IL, the Brooklyn and Amsterdam studio of Florian Idenburg and Jing Liu, wrapped it in bespoke pink precast concrete, stacked like a village, for the developer Tankhouse. TH1 is the collector's floor inside it, and the building has been covered widely in the design press, from Dezeen to Brownstoner.
