Mid-Cambridge | 23 Ellery is the rare townhouse that feels less like compromise than distillation: almost 3000 SF over four finished levels, south/east light, two-car parking, and bespoke-home finish quality. Built by Broadbridge, with architecture by John Buckley and interiors by Rebecca Walsh, it has a gorgeous throughline of tone and restraint—warm woods, custom cabinetry, layered lighting, details that feel edited rather than decorated. The main level is gracious and beautifully scaled, anchored by a highly designed, highly useful kitchen with AGA induction cooking and a reclaimed-oak island made for gathering. A porch, fenced garden, and landscaping extend living outside. The primary suite is calm and tailored; the Mansard level is bright, charming, and generous, with skylights over the stair and hall. Below, a richly detailed study opens to a sunken patio, plus family room, bath, and small fifth bedroom for guests or office. Close to Harvard (Red Line/T), Central, MIT/Kendall.
