As one of the winners for an open competition, the concept of the Put Vejini concert stage, by Jevgenijs Busins, Anton Gonda, and Ivo Dzenis, is based on the acoustic possibilities of building. The goal was to achieve maximum acoustic potential using a minimal amount of materials and to get an aesthetically appealing image of a concert hall. More images and architects’ description after the break.
Liepaja concert garden “’Put Vejini’ was an important place of Latvian culture in 20th century, hosting the local scale festivals. Now, the goal is to return this function, to renovate the existing building and to restore the attraction of the site as a place for open-air music and entertainment. Small contemporary cultural space should become a source of pride and a recreational opportunity for each citizen of Liepaja.
The world’s best architect is nature, so the architects have borrowed the natural shape of the oyster shell, which carries good acoustic capabilities and is consistent with the general typology of the building, as well as has a good visual effect.
With the aid of parametric modelling, the architects have created the shape of shells, where edges have not only aesthetic, but also structural and acoustic function. According to the laws of sound distribution, the sound penetrates the edge of shell, absorbs and covers all audience without creating echo effect.
Building supporting frames creates an exoskeleton structure arranged at an angle of glued wooden frames, which are connected by steel rods and covered with a wooden roof. Building self-supporting frames to hang acoustic panels, the glued wooden structures were selected in the context of the park, and taking into account the environmental sensitivity of the material.
The proposal includes two options of the spatial solution. Despite the large visual difference between the two options, the difference is only in the form of the supporting frame section. Plans, elevations, and longitudinal sections of both of the variants are basically identical.
