In her will, the entrepreneur Karoline Goldhofer decreed that a day nursery should be created on the site of her villa, which was situated on the edge of an industrial area. Instead of demolishing the existing building, which was clearly too small for its new function, the architects, Jörg Heiler and Peter Geiger, simply removed a few linking tracts and the low-pitched roof. The three main sections of the villa – the house itself, the garage and the swimming pool – now form the functional core of a structure that is almost twice the size of the original and that now has a flat roof and a translucent polycarbonate outer skin.
