About this House

Enjoy quiet, country-like living in central Boulder with easy access to shopping, excellent schools and medical facilities. The first thing you notice when you drive up is the maple tree bears and eagle sculpture by Boulder artist Lueb Popoff. In front of the garage is a large heart-shaped moss rock boulder. This adobe finished two story home was renovated using architect Karl Whitten's design.The property has been well maintained and cared for and has four bedrooms, four baths and is surrounded by roses in the summer and tranquility in the winter. There are mountain views from the master bedroom upstairs. It has only had two owners. The grounds boast of dozens of varieties of roses from hybrid teas to hardy Canadians. The backyard is enclosed so your pets and children will have plenty of room to play safely. There's also lots of space around the house providing privacy as well.The upstairs master bedroom includes a huge en suite bathroom with Jacuzzi tub, large closet with washer and dryer. There are two bathrooms on the main floor, kitchen, two bedrooms (or offices) and a large entertainment room. In the basement there are another washer and dryer, laundry room, bedroom, and large room for crafts, ping pong or billiard table.This house comes with many extras such as two gas fireplaces, pellet stove, back-yard covered patio providing a great shaded spot in summer for barbecues. The property includes a fantastic bonus: your own garden water well that delivers no-cost water to the lawn sprinkler system. This tranquil house is near walking and biking paths, bus routes, groceries, restaurants and more. And if that's not enough, imagine watching the Bolder Boulder with your nice new neighbors as the runners pass right in front of your new home!
