About this home
Set among the trees in Mt. Helix, this fully reimagined retreat offers 4 bedrooms, 3.5 baths and 3,308 sq ft of thoughtfully designed living space. Soaring wood-beamed ceilings, expansive windows with views to the top of Mt. Helix and modern fireplaces bring warmth and character throughout. The chef’s kitchen features a ZLINE 6-burner range, Il Forno appliances, Taj Mahal quartzite countertops and a hidden walk-in pantry. The adjacent family room opens to a redwood deck and backyard for effortless indoor-outdoor living. Upstairs, the serene primary suite features a spa-inspired bath with body sprayer and dramatic waterfall shower cascading from a skylight. Downstairs, a flexible bonus room is ideal for a gym, playroom, office or potential 5th bedroom, while a second ensuite offers privacy for guests. Outside, enjoy .44 acres of terraced grounds, redwood decking, potential ADU space and a freshly replastered pool with new energy-efficient equipment. Owned solar, a detached shed with utilities and enclosed dog kennel add functionality. Available furnished, this distinctive property is equally suited as a primary residence, second home or investment opportunity.
