The Engel's relocated to Scottsdale several years ago from the east coast. After purchasing a residence built in the late 80's, an extensive renovation and addition was in order. As the house doubles as the Engel's office and design studio, the addition includes a gallery and art studio that wraps around a large existing mesquite tree. The tree provides shading for the large expanses of glazing incorporated into the design. The existing residence was re-designed to create a new indoor/outdoor relationship and to incorporate a great collection of "pop art". The kitchen is clad with translucent millwork and stainless steel while the adjacent dining room incorporates a large glazed garage door that opens to an outdoor terrace. The master closet is vast and would be the envy of anyone who loves to shop.
