Description
Back on the market! Seller has been busy addressing various concerns made by visitors last Fall. This is a lovely 2-story property on a large corner lot in the very popular Old North Boulder neighborhood. The home opens onto a pleasant living room with a see-thru fireplace and granite hearth. The see-thru fireplace looks into a spacious great room sporting new remote-controlled skylights. Hardwood floors are used throughout main level (and under bedroom carpets). 2nd level primary bedroom includes a huge en suite bathroom, with Jacuzzi, large closet and washer and dryer. Another washer and dryer can be found in the basement, alongside a bedroom and a media/crafts room. An updated kitchen opens onto a large covered brick patio, acting as the centerpiece of the large enclosed backyard.The grounds are home to extensive rose gardens, boasting dozens of roses from hybrid teas to hardy Canadians. A gardener's delight! The Sellers are the second owners of this home and have kept it well-maintained. They are also responsible for the major renovation visible around the property (following a design of Karl Whitten). Great location close to schools, parks, North Boulder public gardens, North Boulder Rec Center, Ideal Market, various restaurants and coffee shops, walking and bus routes!
