Truly reflecting the scale, proportion, and spirit of English Tudor and Elizabethan country estates, ($38,500,000) Chiltern is privately sited on more than six acres in the sought-after community of Hillsborough, California. Close to both the multicultural metropolis of San Francisco and the business and technology center of Silicon Valley, this borough is an ideal place to raise a family in a peaceful and secure environment. One of the West Coast’s largest private residences, Chiltern encompasses an impressive five-bedroom main house of approximately 36,000 square feet, three separate apartments, and an exquisite guest house. The majority of the home’s furnishings and art are included in the purchase, and an additional 2.5-acre parcel is also available. Unique in its aspirations, its quality, and its refinement, Chiltern is a monument to the idea of architecture as art, and a jewel to treasure for generations to come.
