NEO auditoriums
Butong meets parametric design
When Tengbom designed NEO and Technology and Health, they featured two spherical lecture halls, but there was no technical solution as to how the shape would actually be realised. By means of parametric design and the material Butong, a complex design proposal became a reality.
The requirement was to design an exterior that reflects the high-tech, digital “state of the art” interior. It also needed to have the ability to both reflect light and absorb sound. The result became the almost futuristic elements of the world-leading Life Science cluster at Karolinska in Huddinge.
From charcoal sketch to complex formability
With the help of Computational Design, the vision for the auditoriums was realised.
Through a close collaboration with Lars Höglund, founder of Butong, and our digital expert in ArchTech & Future, the complex shapes were developed based on a parametric model – with only a series of charcoal sketches as the foundation.
“We have long had our eyes on Butong as a new opportunity in our façade projects. It is a fusion of bubble wrap and concrete, which forms a malleable and semi-transparent 3D structure.”

The shape was created from a variety of mathematical parameters that can be rendered in 3D, which creates flexibility in the shape that continues until the final pressing of the production button. The finished solution required approximately 3,500 unique parts for the frame and mould, with minimal tolerance over the double curved surfaces of the mould.
When Butong met parametric design, the positive effects were numerous. In addition to being able to design complex environments, zero intermediates and minimal material consumption were required, which was good from both a sustainability and cost saving perspective.
“We adjusted every part of the casting together with the customer,” says Shahrokh Kamyab. “This made the project more time-efficient and allowed us to generate finished production files directly for manufacturing.”
“We regularly work with plant walls, especially green façades. But Tengbom took our material in a completely new direction,” says Lars Höglund, founder of Butong. “They focused on formability and the permeability of light and sound. This solution could only have been created through digital fabrication and parametric design.”
