A modern residential project with around 50 apartments was realized in the middle of Gablitz. The three buildings were constructed entirely using resource-saving solid timber construction methods. The high degree of prefabrication enabled particularly economical and energy-efficient implementation.
The two-stage competition organized by Österreichische Bundesforste AG was won by the innovative architectural concept of Treberspurg & Partner Architekten, Ziviltechniker GesmbH. We were commissioned with the general technical planning – including forward-looking energy technology. The detailed planning was carried out under the supervision of architect DI Heinz Geza Ambrozy.
A central element of the project was the intelligent construction: repetitive timber structures with standardized elements reduce construction and maintenance costs; lateral incisions at the corners of the building led to an optimized building height and were supplemented by cantilevered balcony slabs, for which a special Isokorb element was developed; slender, recessed steel columns limit deformations.
The underground car park was planned around an earth structure that ensures seepage on the site and can withstand even a 150-year flood.
This project sets new standards in sustainable timber construction and serves as a model for resource-efficient building.
