Walking into Treehaven,” the storied ivy-covered English manor in Hillsborough, one is immediately struck by its beauty. Built in 1927 and designed by George Howard Jr., a member of the first American family to settle in the area, the one-of-a-kind mansion was meticulously restored and modernized by the current owners, according to listing agent Nick Corcoleotes of Coldwell Banker in Burlingame. Leaving many of the original period details intact, such as lead glass, beautiful hardwood flooring, fireplaces, and extraordinary millwork throughout, they sought to balance Treehaven’s historical narrative with contemporary life. They did it to masterful perfection.




Design and elegance converge on over 1.5 acres of professionally manicured gardens, walkways, and lawns, making it a truly special setting for family gatherings, galas, and making memories. Over 7,000 square feet of living space unites in an extraordinary floorplan that prioritizes entertaining: a formal living/dining room, a gorgeous lead glass-enclosed breakfast area, a gourmet chef’s kitchen complete with Wolf and Sub-Zero appliances, and a comfortable family room with a fireplace.
