21 Spinnaker is Crystal Cove’s next landmark residence, featuring the highest quality new construction and most sought after design in the region. The estate graces one of the best lots in the enclave, a prime oversized corner site (over 20,600 sf) on Crystal Cove’s smallest, quietest street — providing the most privacy and unobstructed views of ocean, coastline to Palos Verdes, harbor, and sunsets. The new 11,431 sf residence encompasses 5 bedrooms, 7.5 bathrooms with stunning European architecture by famed EBTA Architects. Sophisticated transitional interiors and an open concept floorplan span three levels of casually elegant living with seamless flow from one room to the next and through walls of automated disappearing doors to the sublime grounds. The attention to detail is astounding, with every handcrafted finish, imported material and curated amenity selected for long-lasting appeal and luxury. Dual master suites (one on first level) include a main master with breathtaking views, sitting room with fireplace, his and her spa bathrooms (both with steam showers + dressing rooms), and an expansive terrace. Other highlights: climate-controlled wine wall, large chef’s kitchen and secondary catering kitchen, lower level gym, bar and theater, saltwater pool + spa and pool pavilion, Control 4 home automation, security camera system, Vantage lighting, and an 8+ car subterranean garage.

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
No earlier records were returned by our current sources. This does not mean the home has never sold.
