Lovingly named, "The Terrapin House," to properly convey the unique and charming turtle-like design of this geodesic dream cabin in Coal Creek Canyon. Situated on nearly six acres of Colorado mountain heaven, where a year round spring and summer waterfall + natural rock outcroppings make any ordinary weekend getaway extraordinary. This home was originally designed by Dr. Bruce Bohor as the "model home," for the very chic and environmentally friendly geodesic architecture of the 1970's. This home has stood the test of time and you will see that it is in pristine condition inside and out, with soaring ceilings and an abundance of natural light thought out each carefully crafted space. The front entrance offers a "vestibule, where dropping the day's muddy hiking shoes can keep the inside clean and maintain the temperature inside. The main living area feels like no home you've ever been in, the mountain views from the sliding glass door and deck, are enough to make you fall in love. Cozy up with some coffee or wine by the wood stove and watch the flakes fall or sun set with total peace and tranquility surrounding you. The updated and modern kitchen allows for easy entertaining, with all stainless appliance included. The main level also includes a large office/den, where you can get your work done away from the city with fiber internet and a hidden bed for a third bedroom option (non-conforming) + 3/4 bath, again ideal for guests. Upstairs is open to the main level, where a twin bed sleeping area and primary bedroom are located. The primary has a full bath with dual vanity and walk-in closet. The basement has been updated with a huge guest suite and full bath, perfect and private with walk-out access to the oversized two-car garage and work shop. Your'e only 30 mins to Boulder & Golden, 20 mins to grocery stores and 35 mins to Eldora ski resort. It's like nothing you've experienced, so if it's character you want, this one will deliver. Can come mostly furnished.
