About This Home

538 Marin Ave. is a lovely, spacious 3 bedroom home with a separate and very private additional dwelling unit (ADU) over the garage. The home is set on over a quarter of an acre with a large level grassy lawn that begs to host backyard BBQs. The newly remodeled gourmet kitchen with high ceilings, top of the line appliances, and an oversized island is the hub of the home while the adjacent generously sized dining room offers the perfect setting for many memorable meals. Replete with a wet bar and a raised hearth gas burning brick fireplace, the living room is both a great entertaining space and a cozy place to unwind. With its vaulted ceilings and wall of glass opening on to the garden, it blends seamlessly into the backyard oasis. There is a separate home office/yoga studio in the back garden as well as a fire pit area, an al fresco dining area, and a hot tub. With three bedrooms - each with their own bath - and the au pair/in-law/rental unit over the garage - this home can accommodate many different living situations. The beautiful garden has several mature lilacs and wisteria blooms as well as lemon trees and lavender. There is a seasonal brook that runs behind the property and the there are a myriad of hiking and biking trails close by. Tennessee Valley and Muir Beach are easily accessible and Tam Junction with its shops and restaurants is just moments away.
