Neu-Ulm-Wiley-Süd „Open-House“


High-quality, environmentally aware catalogue module buildings

In the project „open house“, buyers can assemble their individual residential units in apartment buildings using variously priced elements chosen from a “catalogue”. The project was realized in low-energy architecture and meets various ambitious ecological standards.

Following the closure of the Wiley barracks in the south of Neu-Ulm (pop. 50.000) in 1991, a site measuring 76 ha in total became available for urban restructuring and a change of use. The outline plan, which was based on the 1994 town-planning ideas competition for „Wiley-Süd”, divided the area into four development section comprising 2.000 apartments in total. The new district measures about 40 ha and features spaces for various housing concepts, business and service operations, higher education facilities, social infrastructure, and an extensive green space which was connected to the state horticultural show in Wiley-Mitte (20 ha) in 2008.

Project description

Blick auf die Seite des Open House1 im ersten BauabschnittSource: Casa Nova

The project „open house“ is one of several owner-occupier housing projects of model character currently being realized in the first construction stage in Wiley-Süd. The project developers strive to „take into account the ideas of later apartment owners to a large extent“. They provide a basic cubist building structure with loft character and then the buyer is free to choose dimensions, floor arrangements, layouts and fittings from a catalogue.

The buildings are constructed as certified low energy buildings with good sound and thermal insulation, using the latest construction methods and processing technologies. The construction project is aimed at creating self-contained apartments meeting specific ecological standards via environment-conserving building materials, an engine-based co-generator and solar collectors, as well as featuring a sophisticated design.

This project is aimed at making the construction of multi-storey dwellings more attractive for potential developer groups who are looking for individual housing solutions. By virtue of the unconventional marketing and the open architectural concept, the qualities of a free-standing building are also realizable on a larger scale.
