This work describes a house designed by two architects, five artists and a poet. The house is in the medieval centre of Gelnhausen, near Frankfurt. It retains the scale and volume of the previous building on the site - a dilapidated 300-year-old timber structure - but differs from it in all other respects. The interior and exterior of the building present a continuous smooth surface, punctured with many openings. The interior consists of a single room open from the floor to the gable. Grass, olive trees and ivy are planted inside. Five metres above the ground, spanning between the two gable walls, is a box which contains a bedroom and supports a deck. A collaborative work, the houses addresses the public at large through the mediums of architecture, painting, photography, poetry, sculpture, light and noise.
