At first glance, 228 Connecticut Street presents as a classic San Francisco facade: quietly handsome, perfectly at home on one of Potrero Hill's most sun-filled streets. Step inside, and the experience shifts entirely. Fully reimagined in 2005 by acclaimed modernist architect Sandra Vivanco, the residence was conceived as a private urban retreat with a deceptively simple premise: that a home can be both architecturally extraordinary and genuinely wonderful to live in. Four bedrooms, three and a half baths, and four light-filled levels make a compelling case. Vivanco designed the home to move with the light. Panoramic skyline views shift from gold to silver throughout the day, while thoughtful geometry and generous glazing carry that light through every level. Five private outdoor spaces, a walk-out rear garden, and a panoramic roof deck capture both the views and Potrero Hill's famously mild microclimate. The main living level anchors a true great room where kitchen, dining, and living open directly onto two sun-drenched decks, one with a built-in BBQ, the other a quiet perch, both with uninterrupted views. The penthouse-level primary suite crowns the home: a serene sanctuary with spa-inspired bath, walk-in closet, and private rear deck. Three additional bedrooms and two baths along with an expansive family room occupy a single level - a layout as rare as it is practical. On the lower level, a Dolby Atmos media room opens through a glass garage door onto the landscaped rear garden, collapsing the boundary between cinema and outdoors with uncommon ease. Passive heating and cooling, solar, radiant heat, EV infrastructure, and sustainably sourced materials including solid white tigerwood floors complete a residence that performs as beautifully as it looks. Minutes from 18th Street shops and dining, historic Dogpatch, Chase Center, Mission Bay, SFO, and transit. The finest position Potrero Hill has to offer. Architecturally significant. Deeply livable. Entirely one of a kind.
