What's special

Updated appliancesNatural southern exposed yard

A remarkable mid-century modern on a parklike 2.1 acres in the heart of Columbia's Old Southwest. The property is bounded by the MKT Trail to the south, and is a 5-minute walk to MU campus and downtown. The house was designed by famous St Louis architect Harris Armstrong, a protege of Frank Lloyd Wright. The living room is all 12 foot windows framing the natural southern exposed yard. The fireplace is the centerpiece of the room, with copper hood. There are 3 bedrooms cantilevered to the west, all overlooking the acreage. The kitchen has all updated appliances while maintaining the original intended charm. The lower level can be used as a family room and a bedroom (or two), but can also be used as a separate rental property, with a second kitchen. This house is exquisite.
