League Studio worked with a pair of artists and Park Slope pioneers to expand, transform and daylight their home of 25 years. Their top floor two bedroom apartment was reconfigured to allow for roof access and an open kitchen. Storage space was maximized by making use of the high ceilings. A spiral stair case was installed surrounded by 1 ½ story bookcases. The roof top structure provides an intimate reading nook and garden storage. A large window and a skylight flood the apartment with daylight.
