At our latest project in Mar Vista, we've designed a home that will go up two stories and down one. The 8,000-square-foot house will include seven bedrooms, nine bathrooms and a basement level that features a screening room, gym, au pair living quarters and a wine cellar. Like all of our homes, the outside is just as important as what goes on within: Here, glass walls disappear to invite gardens, the pool area and courtyards as completely livable environments.
