Introducing an unprecedented opportunity to acquire one of the most significant waterfront compounds in Colorado's Front Range. Spanning nearly 50 combined acres of pristine Boulder County landscape, this legacy estate consists of four distinct parcels anchored by a massive 16.6-acre, spring-fed private lake and the invaluable ownership of 1.36 shares of the Palmerton Ditch. Offering a level of recreational freedom and private water access that is nearly impossible to replicate, the North Lake House Lot at 0 Rozena Drive encompasses the entire private lake, and includes a designated buildable envelope for a 6,500-square-foot residence positioned directly at the shoreline with unobstructed views of Longs Peak. The lake has produced trophy catches including 27" bass and 17" crappie, sitting alongside a pond fed by the Longmont Supply Ditch. Whether enjoying a paddle board session or navigating the picturesque path encircling the water, the estate offers a profound connection to a thriving ecosystem. Beyond the shoreline, the residential offerings are equally remarkable, beginning with a stately gated entrance and winding drive. The primary residence is a masterpiece of light and glass, featuring a sun-drenched atrium and stone fireplaces. Outdoor living is defined by a pool, pool house, and kitchen, set against the backdrop of Burch Lake and private fruit orchards. Complementing the home is a multifunctional barn with an office, kitchen, and equestrian stalls. An adjacent parcel, currently a hay farm, offers flexibility to expand with an allowable 5,500-square-foot residence site. The footprint is completed with the fourth parcel, protected by an agricultural conservation easement, ensuring permanent privacy. With Palmerton Ditch shares providing an abundant water supply, the land remains productive and beautiful. This is a rare intersection of pastoral seclusion and world-class luxury, offering the singular privilege of a life where the horizon is yours alone.
