5. Open and bright in New York. Joseph Eisner and his team at Eisner Design transformed a bare-bones basement into this open, light, and multi-purpose space. The family in Westchester, New York, wanted the space to include room for a home office, a gym, a bar/lounge, a guest bedroom, and a large play area. The design was more about taking away elements than adding them. A large glazed wall with sliding glass doors is located to the right of the home gym. In the initial construction, this was a large foundation wall, which Eisner and his team removed to open up the space.
