3035 Canyon Road presents a rare opportunity to create a custom Burlingame Hills estate anchored by history, privacy, and architectural flexibility. The property allows a by-right rebuild of the main residence while preserving a fully permitted, separately metered guest house, a separate three-car garage, and pool, all immediately usable. City records reflect approximately 5400 sq ft allowable floor area; buyers to verify redevelopment or expansion potential. Distinquishing the estate is a hand-excavated stone retreat carved into a hillside outcropping, complete with stairways, two caves, and a viewing deck with Bay views attributed to Charles Fey, the San Francisco inventor whose Liberty Bell machine laid the foundation for the modern slot machine. Existing secondary structures may be architecturally refined on the exterior only, allowing a future owner to unify the estates design while concentrating capital on the primary residence. The guesthouse and garage are presently rented month to month for $5000. This is a property for buyers who value provenance, discretion, and the ability to create something truly one-of-one in the Burlingame Hills. The owner of this property is also the licensed real estate broker.
