Dazzling butterfly-roof mid-century classic designed by The Architects Collaborative (TAC) in the timeless modernist enclave of Five Fields. Situated on a large corner lot, this much-admired updated home retains the hallmarks of TAC's design - post-and-beam construction, open plan, soaring ceilings, and walls of windows that fill the space with natural light. A sense of Zen that permeates upon entering the 2008 addition - foyer, mudroom, shoji-screened hall, + a great room that also works as a large office, or guest space, and which could be divided. It has a mini-split AC/heat pump, though the house has central air. The kitchen features top appliances and is open to a dining room and a living room with a gas fireplace. Sliders open to a deck overlooking the stone-walled grounds. The bedroom level has 3 bedrooms and a full bath. A 2nd full bath is off the kitchen entrance. The lower level has a playroom. The beloved Five Fields neighborhood has a swimming pool, playground, and more.
