A sprawling Woodside estate once home to Silicon Valley pioneer Gordon Moore is hitting the market for $29.5 million. 

The Intel co-founder bought the 25-acre Phleger Estate residence in 1991 for about $6 million, The Wall Street Journal reported. The 98-year-old home at 100 Cañada Road stands as a remnant of the past in the hills of Woodside

Moore bought the home and the surrounding 24 acres to preserve the historic Phleger Estate from being redeveloped. The nonprofit land conservation group Peninsula Open Space Trust purchased the rest of the original 1,315-acre estate from the family of prominent San Francisco lawyer Herman Phleger and transferred the property to the National Park Service to become a public park. 

Moore died in March 2023 at age 94; his wife Betty died at 95 that December. He left his estate to Peninsula Open Space Trust, which is now selling the home.

The Tudor Revival-style main house, known as Mountain Meadow, was originally built in 1927 and boasts six bedrooms across 9,300 square feet. 

Throughout their three decades at the home, the Moores spent about $15 million renovating and improving the property. This included expanding the kitchen but preserving original elements like redwood paneling and five wood-burning fireplaces. They restored the home’s original call-button system for staff and maintained the vault in the butler’s pantry meant for valuables like silver, jewelry and china. 

“The Moores paid careful attention to preserving and maintaining the originality of the structure,” Gordon Clark, president of the Peninsula Open Space Trust, told the Journal.

In 1994, shortly after moving in, the couple built a 2,500-square-foot caretakers’ house. They completed the property with a pool, tennis court and greenhouse. 

Hugh Cornish of Coldwell Banker Realty has the listing with Erika Demma of Compass.

The estate is safe from large-scale development thanks to a conservation easement on the property.  

It’s not the only Moore manse for sale. Their home on the Kohala Coast of Hawaii’s Big Island was listed in February for $28.8 million and has dropped in asking price to $21.9 million. 

Woodside remains an attractive option for wealthy Bay Area residents. Last year, the most expensive home sale in the incorporated town was $52 million.
