The “paper house” won first prize in the architecture competition “mobile working spaces” and was opened at the Zollverein mine site on September 9, 2010.
Temporary structures are being used more and more in our industry, especially in instances when additional space is needed for a limited period of time, such as the Olympic Games or the European Capital of Culture year. As a provider of construction services oriented to the needs of the future, HOCHTIEF always plays an active role in sustainable building. This is why I also support the development of new, recyclable building materials–like those used here in the paper house.
In 2007 the ASU planning office Dratz from Oberhausen took part in the architecture competition “mobile working spaces” with its unusual idea of constructing houses from recycled paper–and carried off the first prize. The winning project was opened in September 2010 on the site of the former Zollverein coal mine in Essen. It’s part of the official program for the European Capital of Culture 2010 “Essen for the Ruhr”. In addition to HOCHTIEF’s role as a sponsor, trainees from the company built the concrete foundation for the house.
The temporary structure features 180 square meters of useful floor space as well as two small storage rooms and sanitary facilities. A counter made of bales of paper and chipboard panels is also integrated into the building. The glass wall in the rear of the building provides a view of a birch forest, which symbolizes the ecological wood-paper cycle.
The structure is very well insulated thanks to the use of paper as a building material, and the interior climate is very pleasant. In summer, for example, the indoor temperature is about ten degrees Celsius lower than the outdoor temperature, eliminating the need for air conditioning. In the winter months the body heat of visitors contributes to the basal heating of the rooms, so the heating system only has to be used as needed–an effective energy-saving concept.
The roof of the paper house can also be used as a terrace. Pyramid-shaped steps serve as seating and provide access to the roof.
Anyone who is looking for an unusual location with sustainable design features should certainly visit the paper house. Zeche Zollverein, Martin Kremmer Straße, 45309 Essen.
