Originally a small artist's studio located on New York's Upper West Side, this spacious third floor apartment was completely renovated by WorkshopAPD to create a coherent, elegant space for a family of five.

The sophisticated, functional home also boasts a number of dramatic, playful architectural features including a curved glass, wood and metal staircase and sky-high dual climbing walls in the turret playroom. Meanwhile, the interiors reflect the young family’s modern, eclectic tastes.

The apartment is encircled by a dramatic spiral staircase.  "You feel very curious as you walk through it," says Kotchen. Every turn is a wonder moment. It is hard to believe that this apartment even exists. The second floor's kitchen is a painting made of light wood and concrete. Other bright spots in the home include a turquoise chair and cabinet in the second-floor area, and a teal sofa in the living room's central part.
