In 1991, Gordon Moore paid about $6 million for a large property in Woodside, California, adding a substantial private estate to the life of one of Silicon Valley’s best-known figures. Almost three decades later, Moore’s estate placed the property under a permanent conservation easement, limiting what could be built or changed across the site.According to The Wall Street Journal 2025 reports, the property was listed for $29.5 million, covers about 25 acres and includes an English Manor-style house dating to around 1927. There are gardens, redwood groves, walking trails, a creek and an old apple orchard, along with several buildings and recreational facilities.
