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.
