For the very first time in its storied history, this 1936 family estate is being offered to the public. This classic English Tudor is a landmark in its own right, a home that gracefully bridges Hillsborough's past and present. Set on nearly an acre of level land with views of the Bay and San Francisco skyline, the residence embodies timeless elegance. Its centerpiece is a remarkable floating spiral staircase anchored only at the bottom and top. With a large open kitchen connecting to the family room, plus 5 bedrooms and 5 full bathrooms (2 half baths), the estate is ready and waiting for its next owner (some photos are virtually staged)! There is a bedroom, library and full bathroom on the main level. The primary bedroom and 3 add'l bedrooms are upstairs. Outdoors, the gardens carry the signature of renowned landscape architect Thomas Church, whose designs shaped much of California's most beautiful private estates with broad lawns, graceful plantings and private spaces. Built by the Wisnoms, one of the founding families of San Mateo, The National Bank of San Mateo and cousins of Wisnoms Hardware family. This offering represents a rare opportunity: to own a piece of Hillsborough history and to become the next steward of a home designed with both legacy and livability at its core.
