About This Home

Exceptional Happy Valley Land Cannot Be Recreated. Some opportunities are defined by architecture. Others are defined by land. This is the BEST of both worlds. One of the last truly extraordinary estate parcels in Happy Valley where 1.32± acres of LEVEL breathtaking grounds create a setting that simply cannot be replicated today. Perfectly positioned within the landscape, the existing single-level residence offers over 3,400± square feet to enjoy immediately, thoughtfully enhance, expand over time, or reimagine into a design entirely around your vision. Towering redwoods, sprawling lawns, mature rose gardens, a charming 50 year plus producing vineyard, fruit trees, private tennis court, and remarkable privacy create an environment that feels worlds away, yet just minutes from downtown Lafayette’s acclaimed restaurants, boutique shopping, and everyday conveniences. Located near Happy Valley Elementary School, ranked among the top 1% of California public elementary schools based on statewide academic performance. (publicschoolreview.com/happy-valley-elementary-school-profile/94549) Check with school district for availability. Properties like this are increasingly rare. The land is irreplaceable.
