Pierre Koenig’s Case Study House #21 is as iconic as it gets. It is truly one of the most recognized mid century homes in the Los Angeles area. There are some nights I can’t find anything to post about. I may just be a little picky. Case Study House #21 has been on the market for a little while now. The house was a true prototype in the use of materials and structure. I have always love how the home was surrounded by reflecting pools. I am sure the pools were also used to cool the house as the water was circulated up to the roof and back down into the ponds. The low slung single story house has always been a favorite of mine as far as shape goes. Even if you know all about the house you never get tired of seeing it.
