Longs Peak Ranch is your Colorado dream with 90 acres of pristine waterfront land stretching out in hues of green, blue and gold nestled in a breathtaking mountain landscape spanning the Flatirons to beyond Longs Peak. This is legacy land where the grandeur evokes a sense of peace and tranquility as well as a feeling of adventure and exploration. The centerpiece of this expansive, gated waterfront estate is an impressive 9700 sqft main residence with an indoor-outdoor pool and spa. The home embodies Colorado mid modern architecture with a focus on lofty ceilings and walls of glass oriented to capture the pastoral views and offer a connection to the abundant nature outside. Multiple rooms for living and entertaining are interconnected without walls creating a seamless flow of movement and openness. Organic elements of wood, glass, and stone enhance the interior aesthetics and promote harmony. Crafted with the finest materials available at the time of construction, enjoy the home in its current eminence or refresh it to reflect your own style. A ready to finish walk out basement presents an exciting opportunity to double the living space. Immerse yourself in the year round indoor-outdoor pool and spa oasis that redefines the staycation. Down a winding, tree-lined path, you will find the charming two bedroom rancher's cottage with a bonus attached studio and enormous garage. A 3500 sqft outbuilding with a full bath and office provides ample equipment storage or an enviable showroom for a car collection. Two livestock structures, a corral, cattle grids, abundant water rights, and endless acres of pasture for grazing and growing effect an optimal farm environment. The included buildable 40 acre parcel can become a waterfront tract with a simple lot line adjustment. Unplug your family and tune into nature while you swim and camp under the stars, ride horses, run cattle, catch butterflies, fish in the pond, listen to the birds and crickets or just breathe in the fresh air.
