Tah.Mah.Lah. Residence
Portola Valley, California

Sustainable. Regenerative. Home. The Tah.Mah.Lah. residence, located in the San Francisco Bay Area, is one of the greenest homes in its class in the United States. Its owners set about building a net zero-energy, zero-carbon emission home producing a regenerative effect by making more energy than it uses, restoring habitat, saving and repurposing water, reducing and reusing waste. It’s a home that will sustain itself for generations to come, serving as a living demonstration of what building green can be.


What’s in a Name?

Tah.Mah.Lah. is the Native American Ohlone word for mountain lion or puma, chosen by the owners out of respect for the native cats with whom they share the Portola Valley ecosystem.
