Key details
About this home
The historically designated Casady Home is a rare example of single-level Southern California Mid-Century Modern architecture, set at the end of a private Mount Helix road and benefiting from substantial Mills Act tax savings. Designed by acclaimed architect Art Decker in 1961 and built by noted Mid-Century craftsman John Mortenson, the home was later purchased by Decker himself, who lived there for more than five decades. Original architectural details, custom millwork, extensive built-in storage, walls of glass, and seamless indoor-outdoor flow remain remarkably intact, complemented by thoughtful modern updates including custom cabinetry, high-end appliances, premium fixtures, and a permitted office/flex space.
