Sitting on 2.5 serene acres, 1642 Las Trampas is an exquisite California Contemporary designed by John Nance and built by the current owner in 1981. The architecture was influenced by the ground-breaking style of Northern California’s Sea Ranch community which were built with natural wood siding and sloping roofs to blend in with the rugged landscape.

The home was built without grading to maintain the natural topography and be in harmony with the oak studded hillside. The home’s organic mid-century exterior pleasantly contrasts with the California Modernist interior: clean lines, geometric patterns, exposed ducting, key hole doorways, curved walls and port hole windows.

The property is set back from the street on a park-like private cul-de-sac surrounded by mature oak trees. To the right is the private garden area and the garage with a 300sf office and half bathroom; ahead is the distinguished barn with massive stable doors, hay loft and stained glass window; to the left is the sport court currently configured for paddle tennis and access to the cable tram.

Arrive at the front door from the tram or enjoy the vistas while meandering up the front stairwell. The owner purchased the first lot and barn in 1978 and spent two years sitting on the hillside determining how to build their home without impacting the environment. This work of art is the culmination of their dreams.

    The house is located in Alamo’s Westside neighborhood less than a 10-minute walk into town. Downtown Walnut Creek is 4 miles away and you can be in San Francisco in 35 minutes. Alamo’s K-12 public schools all receive Great Schools scores of 10.
