The apartment, a 240-square-foot shoebox with a sleeping loft over the kitchen. Brooklyn architect Tim Seggerman, who renovated this Upper West Side brownstone studio into what it is today. His solution was to insert what he calls a “crafted jewel box” into the undersize space, creating an enveloping cabin of blond woods. “It’s basically a piece of woodwork,” says Seggerman. “I’m very proud of that.” There are cabinets of cypress and bamboo; a gently chamfered ash-and-beech staircase; flooring of quartered white oak; a desk of red birch slats that slips out into the living space… And A nook creates a cubby-like library to crawl into.
