Memorial Day isn’t actually the first day of summer (that is June 21) but today in Los Angeles it is a perfect sunny 70 degrees. It feels like everyone should be at the beach or hiking or at least outdoors. For those of us at our desks I’ve found two treehouse offices. I love the idea of working high above the garden surrounded by green. Below is a timber-lined office in Brentwood, Los Angeles designed by Rockefeller Partners Architects.
