Moksha is a house about renewal, formed of an aggregation of structures tumbled across a rolling hill in Portola Valley, California. Designed by Dan Spiegel and Megumi Aihara of SAW, it sets a contemplative frame around the layered material conditions of inhabiting a specific place over time. For the architects and their clients, it was a decade-long journey of friendship and resilience

A Site of Dramatic Beauty

Set atop a 3.1-acre site, the town of Portola Valley unfurls in rolling hillsides with panoramic views stretching across the Stanford University campus to the San Francisco Bay. Moksha reveals itself gradually, culminating in a sculpted composition of expressive material forms. The landscape and architecture balance presence and restraint—a study in enduring figures shaped by light and time.

A Deeply Personal Foundation

Moksha was designed for Aruna and Sanjiv Gambhir, longtime clients and close friends of the architects. The project was intended to provide a space for reflection following the loss of their son, Milan, to cancer in 2015. The name "Moksha," suggested by Aruna, refers to a release from the cycle of life and death, reflecting the home's emotional and spiritual foundation.

Tragically, during the complex permitting and construction process, both Aruna and Sanjiv also passed away from cancer. Aruna, resolute, saw the project through as a continuation of her family’s story. Today, the house stands as their legacy; proceeds from its sale support cancer research at Stanford.

Material Integrity and Sustainability

The architects selected materials for their ability to weather gracefully, embracing aging as a design principle. Robust concrete walls enclose the ground floor, offering resistance to wildfires and earthquakes. The concrete includes high fly-ash content to reduce its carbon footprint, while its sawtooth formwork casts soft, shifting shadows. Above, the structure is clad in reclaimed old-growth redwood salvaged from nearby forests after wildfires and landslides. As it weathers, the wood silvers with a luminous sheen, deepening the connection to the site’s history. Inside, custom-milled blue-gum eucalyptus floors provide warmth and durability, designed to evolve in character over decades of family life.

A Home of Moments

The home balances vast outward views with moments of stillness. A contemplative courtyard and pool court provide inward focus, while the great room opens entirely to capture the valley. The primary suite cantilevers over the slope, hovering with a sense of quiet elevation. Moksha remains a meditation on loss, transformation, and connection - a home where every material and line of light holds a memory.
