Loft

Illuminated by a String Light from Flos, the bedroom embraces the loft’s palette with a side table, duvet, and pillows by HAY.

This New York City home is studded with pieces by such famous names as Knoll, Saarinen, and Risom. Deployed throughout the loft, these modern icons at once unify and separate work and life. Like the architecture, they can be read two ways: as recognizably typical office furniture or as prized home-design collectibles.

Kartheiser's courtyard also includes a dry sauna with a ceiling made from 2,500 pieces of wood.

Futuristic floating stairs lead to the loft’s mezzanine. Throughout the lower level, natural stone was chosen for the flooring, laid at an irregular angle to add visual interest.

One entire wall of the space is dedicated to storage. A simple, clean iron rod shelving system was conceptualized to span the entire wall left to right, and both floors top to bottom. Depending on the location of the storage wall, the nondescript iron grid can be used to house items in the living room, kitchen, library, or bedroom areas.
