J+K Residence is a three-story residence that combines two classic New York housing types with a twist: an historic loft and a townhouse. Set on the roof of an historic Second Empire style building, this addition features a two-story living room, twenty-four-foot library, master bedroom suite flowing into a terrace garden, and an outdoor living room with rooftop kitchen. The architecture balances contemporary design with revealing the building’s history, and celebrates the evolving lifestyle and verticality of Manhattan.
