Upper West Side Limestone
This five-story limestone house off Riverside Drive was a bunch of little units before our single-family conversion. And a deep L-shape at the back of the house made for ungainly room shapes and dark interiors. To flood the rooms with sunlight, we straightened the back wall and opened it to the garden with large steel windows. We restored the historic façade and stained-glass windows, while seamlessly cutting new openings into the stonework. At the garden level, we ran bluestone paving indoors and out to connect with the landscape. The master suite boasts a private terrace and a sky lit bathroom with a teak-floored shower. The glass bulkhead and open-riser stair bring light down through the core of the house. With its black metal gate, the elevator may look original to the old house, but we inserted it to ease the climb to the roof deck.
