Specialists from Perm National Research Polytechnic University (PNRPU) have developed designs for wooden high-rise buildings in the shape of polyhedra. This is the first engineering project in Russia for the construction of wooden high-rise buildings with non-standard architecture.
The hexagonal shape provides better airflow, reducing wind load and heat loss during the cold season. This configuration allows for more windows on the south side, which reduces heating and electricity costs. Polyhedral buildings also better withstand seismic shocks of 7–8 points due to a larger number of load-bearing faces.
As the main material, the authors propose cross-laminated timber (CLT) — several layers of boards glued under pressure perpendicular to each other. Structurally, the material resembles plywood, but instead of veneer, solid boards are used. This technology gives the panels increased rigidity and resistance to deformation. The weight of the structures is five times less than reinforced concrete, which allows for the use of a lighter and cheaper foundation, and construction can be done two to three times faster and year-round.
The development is especially relevant in light of new building codes, effective from April 2026, which permit the construction of wooden apartment buildings up to 15 meters high. CLT technologies are already successfully used in Norway, Great Britain, Germany, the USA, and other countries.
