Blending timeless Craftsman character with warm Mid-Century influences, this 1911 multi-structure property at 484 Summit Avenue offers a rare Mill Valley retreat defined by light, flexibility, and indoor-outdoor living. A classic brick pathway leads to the etched-glass front entry, where vaulted ceilings and clean sightlines introduce a bright great room uniting kitchen, dining, and living spaces. The kitchen pairs natural textures with modern function, featuring butcher block countertops, new appliances, and easy flow for everyday living and entertaining. Sliding glass doors open to a rear deck, while hardwood and tile flooring provide continuity and warmth throughout. Just beyond, the living room embodies the home's architectural fusion with open beam ceilings, skylights, expansive windows, and a working fireplace creating an inviting atmosphere framed by garden views. Bedrooms are thoughtfully arranged for privacy, including a hall bath with vintage cast-iron tub, a secondary bedroom with nearby bath featuring a shower-tub combination, and a serene primary suite filled with natural light and direct backyard access. Enhancing the property's versatility are two additional structures. The former garage has been reimagined as a sunlit Craftsman-inspired office with arched windows, vaulted ceilings, and convenient toilet closet. A separate retreat building offers a cozy sitting area, dining nook, fireplace, two bedrooms, and bath with walk-in shower providing comfortable guest or creative space. Outdoor living reflects the relaxed Mill Valley lifestyle with flagstone pathways, decks, pergola seating, fruit trees, roses, vegetable beds, storage shed, and a fire pit area all moments from downtown Mill Valley's shops, dining, and surrounding trail systems.
