About this home

Hidden in plain sight. Designed to blend discreetly into its traditional Cambridge neighborhood, 11 Brown Street offers no hint of the extraordinary world within. Its discretion bespeaks a quiet confidence: luxury measured not by outward display, but by the quality of life experienced inside. Conceived in collaboration with Mariana Ibanez, Chair of UCLA's Department of Architecture and Urban Design, the home unfolds through luminous spaces, sculptural forms, and intimate connections to nature. Generous proportions retain a human scale, while rich natural materials, exquisite craftsmanship, and carefully orchestrated light create an atmosphere both exhilarating and tranquil. As daylight moves through the home, shifting perspectives reveal new moments of wonder. A serene library and upper-level family room offer inviting retreats, while two distinctive fire features bring warmth and drama. Thoughtfully arranged spaces for cooking, dining, and entertaining celebrate the intimate pleasures of gatherings large and small. Sumptuous baths and a private spa with sauna and steam offer restoration, while sophisticated technology works intuitively in the background to enrich daily life. A main-level suite with private entrance provides flexibility for guests or multigenerational living. The garden level offers media and fitness spaces, a second kitchen, and an au pair suite. Indoors and out flow seamlessly into expansive, tree-framed grounds, with unusually long, private views just blocks from Harvard Square. This private oasis reveals its enchantments only to those invited within. A truly extraordinary setting in which to practice the art of living deeply.
