Opening home details…
Ideally positioned on a private corner lot at the end of a serene cul-de-sac, 21 Observatory seamlessly blends sophisticated design with luxurious upgrades. This renovated & recently refreshed residence showcases 4 bedrooms, 3.5 bathrooms, and approximately 3,631 square feet of impeccably curated living space. Every detail has been thoughtfully considered from 18”x36” limestone and European oak flooring to custom inlaid cabinetry, striking Calacatta marble countertops, and artisan-crafted ironwork. A state-of-the-art Lutron lighting system sets the perfect ambiance throughout, while a suite of premium Viking and Sub-Zero appliances enhances both function and form in the chef’s kitchen. The garage is a standout feature in itself, offering Cleaf cabinetry which makes it feel more like a high-end showroom than a utility space. Upstairs, the primary suite is a true retreat, featuring warm wood flooring, a stone-wrapped balcony, and a spa-inspired bathroom with marble flooring, an oversized stone shower, freestanding Hydro-spa tub, and a fully customized walk-in closet. Located within a 24-hour guard-gated community, residents enjoy resort-style amenities including an Olympic-sized heated pool, spa, toddler pool, outdoor barbecues, a grand fireplace lounge, and direct access to scenic Coastal Peak Park. Just moments from award-winning schools, upscale shopping, dining, and pristine beaches, this home offers the ultimate in privacy, luxury, and lifestyle.

No weekly rateNo published rate within 7 days of this date.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.
