Located in the heart of Mill Valley's most prestigious and beloved neighborhoods, this Sycamore Park custom dream home was recently built new from ground up in 2024. Not one phase was overlooked from start to finish with this multi-year building experience including the design, planning, permitting, and construction. With the influence of the owner's attention to detail and careful vision, the highly respected and reputable local contractor Tamalpais Construction executed top craftsmanship into this stunning home that will be enjoyed by generations to come. Designed thoughtfully at approximately 2,292 square feet of living space, the home has the ideal layout with an open floor plan consisting of the kitchen, living room and dining room combined as one great room with soaring 14-foot-high vaulted ceilings. The magazine-worthy kitchen features an eat-in banquette area, oversized island with breakfast bar seating, custom cabinetry and much more. All day natural light pours into the home from a 16-foot sliding glass pocket door that was strategically designed and installed to provide an indoor and outdoor living experience with direct access to the deck with gas fire pit and fenced level backyard. There is a total of 3BR/3BA plus a dedicated home office that could be used as the fourth bedroom if needed. Constructed for all phases of life, the spacious primary suite bedroom is located on the main living level of the home with a luxury resort-like bathroom featuring custom dual sink vanity, soaking tub, Limestone cobble floor tiles, and walk-in closet. The modern-day finishes have been carefully sourced, hand-picked, and curated to provide warmth, style and comfort by choosing top-quality timeless finishes that will stand the test of time. Imported finishes and fixtures properly chosen to execute the vision such as deVol fixtures from England, an Italian ILIVE 6-burner gas range, built-in 42-inch double door Sub-Zero Refrigerator, honed Carrera marble stone, handmade Moroccan ceramic tiles, and wide planked oak wood floors, just to name a few. The home is also highlighted by a one-car garage plus driveway parking, air conditioning, cherished Mount Tamalpais views and a sunny peaceful rooftop balcony. Professionally designed landscaping was implemented and has matured since installation to provide a serene setting and privacy. This is a rare opportunity to avoid the long challenging and costly experience of building a brand-new home in Mill Valley.
