Property Description


9.14 Acres Lot
Built in 2000
For Sale - Active
Units n/a

Where the foothills meet the plains, this 9.13-acre estate offers natural beauty, timeless design, and sustainable living. Backing to Rabbit Mountain Open Space and hundreds of acres of protected land, it provides sweeping views, abundant wildlife, and privacy just 10 minutes from Longmont and 30 from Boulder. At its heart is a Provence-inspired farmhouse, remodeled by a European antiques dealer to blend Old World craftsmanship with modern comfort. Hand-carved Catalan doors, a French arched iron window, reclaimed oak floors, and original iron hardware create authenticity and warmth. Designer lighting and oversized windows fill each space with light, while a wall of glass along the southern fa ade frames the outdoors. The main level features a sunlit dining room with wood-burning fireplace, a cozy living area, and a bright corner office. The chef's kitchen boasts marble and wood countertops, open shelving, and upscale appliances including a vented Gaggenau range, Gaggenau wall ovens, Thermador refrigerator, Sub Zero drawers, and wine fridge. A pantry, scullery, laundry, powder bath, and secondary bedroom suite with en suite bath complete this level. Upstairs, a vaulted family room leads to the private primary suite, where Longs Peak views frame a serene retreat with ample closets and a spa bathroom with soaking tub, bench shower, and double vanity. Established gardens overflow with roses, peonies, hydrangeas, irises, and fruit plantings. A fenced garden with raised beds and shed leads to a cottonwood grove, two seasonal ponds, and the Little Thompson River, home to abundant wildlife. A newly built 3,600-sq-ft multi-use structure offers Marvin windows, super-insulated construction, a 19kW solar array, and three-zone heat pumps for near net-zero energy. It includes a vaulted flex space, guest suite with kitchenette, workshop, storage, garage, and shaded patio. 15789 N 83rd Street is a rare Boulder County opportunity where design, ecology, and lifestyle unite.
