Das Traumhaus on AllMovie

When four young people move into a run-down villa in West Berlin, their attempts at converting it into an environmentally friendly place with a garden and a few farm animals just begin to bear fruit when the city notifies them that the whole place is to be razed - a modern housing complex is going up. The architect-father of one of the young women in the villa (formerly unaware he even had a daughter) is inveigled into taking up their cause and the five of them go to bat against the woman contractor in charge of the new development project. It turns out that the architect and the contractor had known each other before, making his task all the more challenging. Inspired by the commitment of the four youths, the architect installs solar panels, does a major rehaul on the house, hopefully enough to convince the city to rescind their order to destroy it. Time is running short, and the four youths gear up to face whatever may happen.
