Beautifully situated two-family house in the countryside - property value: approx. 500,000 €

This charming, detached architect's house was individually planned in the 1960s by the architects Wiessner & Rogler Schwabach for my grandfather, Mr. Julius Schuler, a master glazier, according to his personal wishes and built to the highest standards of craftsmanship.
The natural, quiet location "Am Wiesengrund" is an oasis of relaxation for you and your loved ones. You can be in the middle of the countryside in two minutes on foot and, with a bit of luck, watch beavers feeding. In ten to 15 minutes you can walk through nature and along the Schwabach to the Schwabach market square.
