56 Walnut Avenue

56 Walnut is the quintessential Sycamore Park home, designed by Mill Valley architect, Danny Castor, with storybook curb appeal that will tug on your heart strings. This home was completely rebuilt in 2005 with all new infrastructure and systems, and perfectly blends period architecture with modern amenities. The welcoming front porch, inviting front lawn and stately mature trees let you know you have arrived somewhere special. This home checks all the boxes with its open floor plan, remodeled finishes, great indoor/outdoor flow, and amazing outdoor space with flat lawn and a separate home office. The versatile great room provides options for people to enjoy time together whether they are cooking, relaxing, or watching a game. The fireplace and built-ins create a cozy living room area for lounging. The kitchen has plenty of custom cabinetry and counter space with a peninsula for casual eating. The adjoining family room provides access directly to the outdoor deck and back yard. There are two bedrooms and a lovely shared bathroom and powder room on this floor. Upstairs is a luxurious primary bedroom with a bathroom that feels like a hotel suite with a huge shower, separate soaking tub, double vanity and great finishes. There is another bedroom on this floor that could equally be a great home office or nursery. The back yard is a magical setting with flat lawn, beautifully landscaped foliage and an enchanting playhouse for the kids. The garage has been partially converted to an office/studio space or could also be the perfect home gym or take it one step further and make it a convenient ADU conversion. This stylish comfortable turn-key home is imbued with local history as well. The composer of the famed song, “I Left My Heart In San Francisco” wrote the music from 56 Walnut. It’s no wonder that this special spot inspired the hit that is an homage to the Bay Area. With its family friendly community, tree-lined streets and central location with easy access to parks, schools, and downtown, Sycamore Park is arguably the most desirable neighborhood in Mill Valley. Enjoy the convenience of this A-plus location and the amenities of this elegant home.
