The K guest house is a small addition to an existing contemporary home in Brentwood, Los Angeles. Within the confines of the site, each design element is positioned to enhance its relationship to the existing house and movement of the sun. The pool house casts no shadows as it provides a backdrop to the pool. It is designed to provide protected living and entertainment spaces adjacent to the pool and accommodate overnight guests. The guest room is oriented to the pool to maximize the intake of natural light and incorporates a slide glazed door system to maximize relationship to the surrounding site. When opened, the sliding doors effectively create an open-air pavilion. The open pavilion theme is further enhanced by the roof design rising from west to east and overhang over the elevated small patio positioned in close proximity to the pool.
