About This Property

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.
