About This Property

Enjoy privacy and exclusivity at this unrivaled Crystal Lane retreat, just 10 minutes from Longmont amenities and 30 minutes from Downtown Boulder. Experience gated, waterfront living at its very best in this stunning showplace featuring huge mountain views, expansive interiors and a bucolic water-front location on 5.57 verdant acres on Boulder County's Crystal Lake. Inside this beautifully remodeled residence, ceilings soar above rich hardwood floors and elegant millwork, while oversized windows frame magnificent vistas in every direction. A covered porch and gracious foyer open to the home's show stopping curved staircase, creating a dramatic first impression. The spectacular kitchen awaits your next culinary achievement with rows of custom cabinetry, granite countertops, and upscale stainless steel appliances. The massive center island is perfect for casual dining. A home office, family room and large laundry room add convenience to the first floor. Outside, lush lawns, towering trees, and meticulously curated gardens stretch to the shores of Crystal Lake. Entertain on the large patio or enjoy a peaceful cup of coffee in the charming gazebo. The outdoor fire pit is the perfect setting for stargazing, or head down to the lake for swimming, kayaking, paddleboarding and fishing. With 5.57 acres all to yourself, you'll never lack peace, privacy and room to roam. The updated main-floor owner's suite boasts tray ceilings, a warm fireplace, walk-in closets and mesmerizing views. In the en suite spa bathroom, discover a custom clawfoot tub, oversized walk-in shower and waterfall vanity. Luxurious accommodations continue with a first-floor secondary suite and two more en suite bedrooms upstairs, both with a private balcony.

There is a lake in Longmont that very few people know exists. Private, no-wake, remarkably serene, it sits behind the gates of one of the area's most exclusive communities. Welcome to 9402 Crystal Ln in Longmont. Set on 5.5 curated acres directly on the water, this lakefront estate is the kind of property that rarely comes up, and rarely comes up at this number. The moment you enter the community, the noise fades. What's left is the lake, the mountains, and a house built to make the most of both. Step inside and the view takes over. It's framed through every main living space, calming and constantly shifting with the light. A sculptural spiral staircase anchors the entry. Formal living and dining rooms bring warmth and elegance, and the main living area, with its custom wood ceilings, has the scale for entertaining and the comfort for everyday life. The kitchen opens straight into that space, and almost every room in the house leads out to its own private deck. Inside and outside blur together here more than in most homes at any price. The primary suite occupies its own wing to the west: a custom walk-in closet, a spa-inspired bath, a soaking tub built for slowing down. Upstairs, two more en-suite bedrooms each open to private decks with sweeping views of Longs Peak and the Boulder Flatirons. Downstairs, a fully renovated private suite with its own entrance, an entertaining space, a gym, a wine cellar area, and room to configure however you need it. More than $1.4 million has gone into this home's improvements alone. Outside, irrigated grounds and curated landscaping turn the property into its own private resort, water features included. Homes like this make a lasting impression. Come see why it was worth the wait.
