In order to solve the lack of space in schools and kindergartens quickly and cost-effectively, the construction of so-called mobile classes using container metal construction has become established. Their structural physics and room climate disadvantages as well as the inadequate design training are unacceptable for neither children nor teachers. The Schluder Architektur team worked with the Schertler company to develop an economically competitive, ecologically more sustainable and architecturally higher-quality alternative using timber construction.

The first prototype was implemented as part of the expansion of the Prückelmayrgasse elementary school. Four new classes were accommodated in a two-story, barrier-free extension connected to the existing building. All wall and ceiling elements were prefabricated in the factory and delivered including insulation, windows and empty piping.

When compared with comparable school extensions using steel container construction or solid construction, the timber construction method proves to be superior in all clearly measurable factors such as construction time, energy indicators and operating costs. Even the construction costs are absolutely competitive with steel containers. The atmospheric and tactile qualities that are conducive to a good school climate in the truest sense of the word cannot be measured, but can be felt.
