For years, tech entrepreneur Asher Waldfogel and his wife, Helyn MacLean, dreamed of building a modern house in Palo Alto, Calif.

The couple, however, worried about clashing with the Mediterranean-style architecture typically associated with their neighborhood of Old Palo Alto.

So they tapped architect Steven Ehrlich to create a design that paid homage to its surroundings with stucco, mahogany and titanium zinc cladding. They spent $20 million over several years building the house, completed in 2005.

Now looking to be closer to their adult daughter on the East Coast, they are putting the five-bedroom home on the market for $44 million—the most expensive listing in Palo Alto.

Waldfogel is an angel investor who co-founded Redback Networks, a telecommunications-equipment company. MacLean previously had a career in fundraising.

The couple purchased the roughly 0.4-acre site for $7.1 million in 2000 and demolished a circa-1930s Spanish Colonial home. The house they built pinwheels around a central staircase. It has 7,900 square feet of livable space, with four distinct courtyards and a pool.

A key feature of the home is a cast-in-place concrete wall, or spine, that is two stories high and about 80 feet long. “There’s a little bit of controlled chaos in what comes out of the form,” unlike a perfectly uniform surface, Waldfogel said. “If you want that, you do it in plastic.”

Ehrlich said it took a few tries to get the concrete wall right.

‘It’s a really hard material to tame,’ Ehrlich said of concrete. Workers learned as they went, and Waldfogel and Helyn grew to appreciate the imperfect material.

Waldfogel said he and his wife are thinking about the next phase of life now that their daughter is grown, although they have not decided where they will move. They also have a home in Sun Valley, Idaho.

“Right now we’re just trying to emotionally let go and decide what to do next,” he said.
