About This Property

One of the most Iconic Homes on Mapleton Hill, the Eastman Reid Collins Home is an historic treasure on a rare 13,802 square foot corner lot. The stunning Tudor Revival style residence has been meticulously maintained by the same owners for 50 years. Now, this classic style home is ready for its next chapter. The appeal of the property is dramatic from the street, highlighted by the timeless brick, stone and stucco exterior details.

A spacious covered front entry and porch welcome you to the home and connect to the porte cochere, perfect for arriving guests. Enter into the foyer and you'll immediately feel the warmth and charm of the perfectly designed and preserved woodworking. Both the spacious living and dining rooms have beautiful beamed ceilings, beveled glass, classic original lighting and built-in cabinetry. The living room opens to a delightful sunroom overlooking the back patio and yard.

The dining room, with vintage tapestries and sideboard/serving area flows into the kitchen which has been remodeled with custom cherry cabinetry. A breakfast room is next to the kitchen. Upstairs, the central hallway accesses the 5 bedrooms and an upper level sunroom. The layout of the generous size bedrooms allows flexibility for new owner to use as they wish.

The primary bedroom opens through french doors to a library/study with built in bookcases and many windows. The hallway connects to a back deck which can easily be enhanced to enjoy the views of the Flatirons. The large attic could be finished if additional space is needed. The lower level of the home is filled with light and includes a cozy family room with fireplace, 587 bottle capacity wine cellar, 3/4 bath and laundry.

Outside, the expansive yard and gardens wrap around the home, encircled by a sandstone and brick wall making the entire area secluded and peaceful. In the spring, the many flowering plants and fruit trees come alive and make the yard and private patio a special place to enjoy this unique setting.
