Extraordinary expansion potential within the envelope! This bright, inviting home on the edge of Sycamore Park offers a large, flat, sunlit backyard and views to the ridgetops of Mill Valley and Sausalito from the open-concept kitchen/living/dining area. Numerous upgrades include central air conditioning, newer electrical service with EV charging, Pella double-pane windows, and a newly remodeled bathroom. Downstairs, a massive unfinished room with tall ceilings offers the opportunity to build your own primary suite, family room, workshop or ADU which opens to the surprisingly tranquil, private and spacious backyard. Built with durable old-growth Douglas fir timber, lath-and-plaster walls, a robust stucco exterior, and updated with tasteful contemporary finishes.
