Timeless elegance abounds this classic residence in a hidden cul-de-sac that shares a story of Hillsborough's past. Built in 1931 as part of the compound for the Clark family while the "House-on-A-Hill" was being built, this carriage house of Cotswold design and influence has evolved into a mini estate on a level lot of approx. 39,000 square feet with complete privacy. The 5704 sq ft main house boasts grand-scale public rooms, high ceilings, beautiful windows and floors. All 5 bedrooms en-suites are on the upper level. The 707 sq ft ADU is a home away from home for extended family and guests. Take your entertainment and gatherings to the outdoors - game day at the pool terrace, practice at the basketball court, afternoon tea or book club at the front or inner courtyard, plant your seasonal veggies or simply take a cool shelter on the deck under the redwood tree. A separate pool house of 568 sq ft is NOT included in the living area. It is quality suburban living at its best!
