About This Property

This is a true opportunity to own one of the finest riverfront properties in the region. There is nothing else like it. Set on 4.74 acres backing to national forest offering unmatched privacy, dramatic mountain-modern architecture, and an spectacular riverside setting. The park-like property has been recently transformed, beginning with the purchase of a neighboring parcel that expanded its footprint and extended its river frontage. The land has been meticulously cleared and landscaped while new outdoor living spaces-including two floating decks for entertaining or outdoor dining, a custom cedar greenhouse, garden shed, new fencing, and obtained river irrigation rights. Beautiful sandstone steps now grace both sides of the bridge leading to the river. A newly re-graded and rocked driveway makes arrival easy. The home and outbuildings were all recently re-stained, and sellers have mitigated the property at the direction of Wildfire Partners (pending certification). Inside, the home blends Colorado warmth and elegance. Dramatic cedar siding and hand-selected river rock define the exterior, while cathedral ceilings with Douglas fir beams and walls of glass flood the interior with natural light. The chef's kitchen features stone counters, artisan white oak cabinetry, and commercial-grade appliances. A double-sided river rock fireplace anchors the main living areas. Three spacious en-suite bedrooms, with the primary suite offering a copper soaking tub, steam shower, and private deck. Designer fixtures, custom railings, and refined finishes elevate every detail. A refurbished studio outbuilding perched on the river is ideal for a workout, yoga, or creative space. All systems have been recently serviced, making this home turnkey. Located minutes from Lyons and Allenspark and an easy drive to Boulder and Longmont, this is a property designed to be experienced. Riverfront estates of this scale, quality, and beauty rarely become available.
