Sierra Skyline solves one of the recurring problems with spectacular Bird Streets houses: what does everybody actually do after they finish looking at the view? Here, somebody thought ahead. The gated contemporary gives you the dramatic double-height living room, oversized art-friendly walls, pool and city panorama you expect this high above Los Angeles, but it also has its own tennis and pickleball court. That changes the rhythm of the stay. Some people can head outside for a match, others can claim the pool, and somebody else can happily stay inside surrounded by art and glass. Nobody has to agree on the itinerary. Sierra Skyline feels less like a trophy house you admire and more like a private hillside club you actually use.
