Hunner Associates

So far, this brand of work has brought Hunner Associates many repeat clients, designers, and engineers that have helped the firm create some of the most beautiful homes.

One of these is the Maywood house which was inspired by the homeowner’s fascination for 1950’s Californian contemporary homes which feature wide and open interior space—the kind of space that welcomes the outdoors inside through large expanses of glass and spacious floor plans. The home has several other distinctive features but its most notable might be the full height brick masonry wall dominating the living room. Earth colored, this wall of oversized brick carries a stacked bond pattern.
