This is a collection of three residential condos APNs 120-73-001, 120-73-002, and 120-73-003 connected by a private common area and sold together as a compound. Perched above the city with sweeping views from downtown Palo Alto to the Santa Cruz Mountains, this architectural triumph known as "The Castle in the Sky" is a true one-of-one. Designed in 2012 by Bellomo Architects as the architect's personal residence, this slag-based concrete compound offers unmatched rarity, security, and exclusivity. Set atop a two-story commercial building and the only residential use in the area, this private enclave offers 17,000 sf of exclusive use space featuring three impeccably designed condos. Each offers 2 bedrooms, 2.5 baths, private balconies, and expansive 1,000 sq ft rooftop gardens with 3 feet of soil for true outdoor living. Fleetwood floor-to-ceiling windows, radiant hydronic heating/cooling, and floating staircases create a seamless, sophisticated design. Multiple layers of controlled access and an 8-vehicle subterranean garage with car elevator ensure protection and discretion. Tucked in the heart of Palo Alto, this hidden fortress above the city provides total seclusion with immediate proximity to the world's most influential tech and business hub.
