The New York firm Rogers Marvel is almost scary in their range and scope: we got vertigo scrolling through their projects, which range from master plans for Dartmouth to Kate Spade shops in San Francisco. We like this simple, barnlike master suite in a sprawling West 29th Street penthouse in New York's flower district, designed for an artist and collector. All the wood used is reclaimed from the fir beams of a demolished New York building, and the floor is polished concrete.
