Sometimes the perfect home doesn't exist, so you have to build it.

That's what tech exec couple Andrea Chavez and Daniel Putterman decided to do, leaving San Francisco for Marin County, Bloomberg reported. 

The couple cofounded Pawscout, a pet-tagging company that they now oversee together; Chavez serves as CEO while Putterman has the title of director. According to his LinkedIn profile, Putterman is also the co-CEO of Kogniz, a company that uses AI to monitor security cameras.

They told Bloomberg that they chose Mill Valley in Marin County outside of San Francisco, because they wanted "the freedom and beauty" of the country.

In 2011, they bought 1.45 acres and began designing their custom home with Quezada Architecture, a 5,000-square-foot main house, plus a guest house, totaling more than 6,500 square feet. Now, the property is listed with Josh Burns of Sotheby's International Realty, asking $12.9 million.

Look inside here.

The property is on a hill, and the main house is actually built into the hill, with three stories. The landscaped lot is relatively private, with sycamores and redwoods, plus plenty of wildlife.
