High-rise buildings from wooden blocks

Researchers at the Lucerne University of Applied Sciences and Arts have developed a concept for high-rise buildings made from stackable wooden modules. They can be adapted for use in various applications and provide a safe means to store CO2.

The high-rise buildings of the future could be constructed from a modular system of building blocks. Researchers at the Lucerne University of Applied Sciences and Arts have developed the module-based concept, which is highly flexible in being suited to a variety of applications, as part of the Holz Hybrid Hoch Haus project.

According to a press release issued by HSLU, Modul17 should be made from 90 per cent wood. The wooden blocks measure 17 meters each along the sides and stand 14.5 meters in height. They are supported by four side pillars which bear the vertical strain and contain the construction technology inside. Access to the module is secured by reinforced concrete staircases, which are built on the exteriors of the modules and additionally help to stabilize overall structure.

The useable space of the module can be freely arranged, for example as a three-storey office module or four-storey apartment complex module with a corresponding number of false ceilings. The room height of the upper part of each module consists of trussgirders that transfer the loads to the sidepillars. Factory buildings, concert halls or even swimming pools are also all feasible.

The exterior design of the buildings can be chosen at will. “It is even possible to retrofit an office building into a residential building – or vice versa – withModul17,” explains Project Leader Frank Keikut from the Competence Center Typology & Planning in Architecture (CCTP) at HSLU in the press release. The module can be stacked as desired or connected in a row.

The researchers have tested a prototype comprising 58 modules that stands at 130 meters in height. The components can be prefabricated. “This often shortens construction times by up to 50 per cent and allows the construction process to be precisely scheduled, which is also ultimately reflected in build costs,” Keikut comments.
