1305 Collingwood Place AUCTION: Bidder registration deadline: 3 December. Competitive starting bids expected. Commanding a coveted Bird Streets promontory, this custom-built estate was crafted for the owners' personal use with no expense spared. Thick walls, expansive marble slabs, travertine flowing indoors and out, and finely crafted wood doors and millwork lend a lasting sense of substance. Sweeping views stretch from Downtown Los Angeles to the Pacific, while a retractable glass wall opens to a resort-caliber deck with an infinity-edge pool, spa, fire features, and barbecue. The primary suite occupies its own level with a private balcony and spa-inspired bath. A Himalayan salt-walled spa and sauna, gym, media room, and wine cellar complete the offering, all orchestrated by Savant smart-home technology. This is elevated Southern California living at its finest.
