Open-air Stage in Penkule, Latvia
The building uses heritage wood building traditions, but to build it we used modern, well-considered solutions to ensure that the building is long-lasting and aesthetically pleasing down to the last detail. For example, there are no visible screws on the entire finish.

DesignRBD in cooperation with ZAZA TIMBER Engineering (previously: Rodentia)
Engineering part of the project
The role of ZAZA TIMBER Engineering (previously: Rodentia) in this project was:
- Structural design development of major structures
- Detail drawings
- Technical drawings for manufacture and assembly.
The frame of load-bearing structures is made up of a glulam pitched cambered beam that is simply supported on glulam columns. The widest span is 13.80 m for the front frame, and each subsequent frame has a smaller height and span, making a roof surface which slopes in two directions.
For wind braces, we used cables instead of steel rods.
Creating a typical connection from the double sloping cantilever beams to the main beams was a challenge. A solution of combining two producer stock connectors was used to avoid custom steel parts for each cantilevered beam.
During the project, the newly-built stage roof was attached to the existing building to ensure that the backstage area was protected from the elements. To achieve this, an additional stone facade wall was added to the existing building which supported the new roof. This also improved the building’s fire safety.
Production part of the project
ZAZA TIMBER Production (previously: IKTK) produced the glulam structures for the stage.
The structures were made of spruce and included 38 types of curved and straight parts. Total number of parts: 88; weight of the largest part: 2.05 t; weight of the smallest part: 10 kg. Total volume: 21 m3; strength class: GL24.
Detail types: curved timber beams of various radiuses and varying heights, columns, cross beams and sill beams.
The 24 cm-wide timber beams were made with differing radiuses (from 18 m to 19 m), lengths (11.7 m to 14.8 m) and heights: the smallest is in the middle—69 cm—while the largest are on each end (150 cm).
This was the first large project for which we used our new Technowood CNC equipment. We did all the necessary milling, drilling and sawing. Assembly at the building site was fast and precise.
Manufacture time: 4 weeks.
