There can't be any doubt that a great deal of the happiness Herrero expresses in his work arises directly out of his own life. In 2001, together with his wife Janet, he designed and constructed a new home in Calistoga. The home virtually brings one of his imaginary Tuscan hill towns to life, with a generous main building, an L-shaped garage-office with a tower, a wine cellar, and a guest house, all made to look like timeworn stone structures.

In 2004, the Herreros converted part of the garage to a light-filled new studio, eliminating the need for Herrero to drive to the Mount St. Helena studio every day. Now, his work is contained within his life, and he is more productive than ever before.
