This is the house of Hildegard Schäfer who takes care and houses the goat Hennes VIII which is the mascot of the German football/soccer team 1 FC Köln (Cologne). Hildegard is a real fan of the team, her house has a red-white mast for the clubs flag and on the side of the house is the clubs coat of arms.
It's living in a stable in the backyard and at every game of 1 FC Köln Hennes is present in their home arena carrying a special FC Köln cape. For these occations Hennes is taken to the stadium by a Ingo Reipka. It's also present to other special events where people want to see him like the local carnival and celebrations.
