Brooklyn firm GRT Architects tackled the renovation of this 1962 home originally designed by Roberta Thrun—one of the first women to graduate with a degree in architecture from Columbia University (and also the client’s grandmother)—in New York's Hudson Valley. The existing 102-foot-long beams were sanded down and treated with a natural wax finish. Throughout the home, the floor is covered with original terra-cotta tiles, which only required a cleaning.
