About this House

Backyard paradise. Spend quiet afternoons on the private back flagstone patio gazing at the Flatiron views. The ditch provides a babbling stream and tranquil ambiance. This oversized corner lot has much to offer with gardens, fruit trees, & southern exposure. Upside potential: most work has already been completed and home is move-in ready. Jaw dropping views from the master bedroom with huge windows and a private patio. Designer finishes in the freshly updated master bath. Three additional secondary bedrooms upstairs including a spacious and bright corner room with mountain views. Exquisite woodwork. Custom cedar fireplace mantel and stairway bannister. Original hardwood floors throughout. Unbeatable location close to CU, nearby trails that are quiet and lesser-known, easy access to Hwy 36.
