About This Home

There is not a new Flight to Quality... it has always been there and it's never leaving. Those who know the difference also know they are never disappointed when buying the best. The estate at 608 Seminary is unlike anything that will come on the market this year. It is a resort of health and wellness as much as it is a fortress of security. It is the ultimate balance of excellence in craftsmanship, in privacy, and in proximity to San Francisco. Getting to Downtown is about the same as it is from Sea Cliff. We actually call it Sea Cliff North. This residence was reimagined over five years in a down-to-the-studs transformation, where best-in-class materials and globally respected brands define every surface and system. No expense was spared and it shows. Arcadia steel windows frame panoramic water views, Lutron lighting and shading make it easy to set moods. The house was built for tranquility. It was built to be a resort. The owners painstakingly created air and water quality systems throughout, critical to long-term health. These are elevated through Lifebreath HEPA filtration and Aprilaire purification systems calibrated for clarity and longevity. And at this Resort, cooking is at the center of it all. The kitchen operates as a professional standard not seen in residential homes: Miele appliances, Gaggenau cooking systems including a Teppanyaki grill, Sub-Zero refrigeration, and Henrybuilt cabinetry, an intersection of engineering and design. Heath ceramics, Artaic mosaics, and custom G2 design elements layer the home with quiet, tactile luxury. But it's the grounds that make this estate live differently. The rarest of trees, palms and exotic plantings were all curated with intention. Balanced within the grounds are the limestone terraces and a poolside designed for both recovery and entertaining. Wellness is fully integrated here with a dedicated sauna with water views and advanced water filtration systems supporting performance and renewal from the inside out. Interiors impress those with the most discerning taste: Boffi, Porcelanosa, Falper, and Jee-O define the bath experience, while bespoke stone, tigerwood paneling, and precision-crafted metalwork underscore a commitment to permanence. The fortress and the Resort. This residence is for those who recognize elite building materials and construction and not trends. Those who are looking for a lifestyle of health, wellness and longevity. Welcome to the Sanctuary.
