Building project combines art, architecture and cultural development
Nüssli has broken ground on the extension to the Mack Pyramid in Monheim. As general contractor, the company plans to celebrate the topping-out ceremony on the 95th birthday of artist Heinz Mack in March 2026.
Nüssli Schweiz AG from Hüttwilen has broken ground on the expansion of the Mack Pyramid in Monheim am Rhein, according to a press release. The Thurgau-based event construction company was awarded the general contract in spring 2025. Following the construction of an eight-court sports hall, this is the second contract from Monheim for Nüssli.
The construction is an architectural and artistic challenge. A second mirrored pyramid will be placed on top of the existing Mack pyramid. Additional exhibition and storage rooms are to be created in the new double structure. The existing space will also be renovated and modernised.
The deep foundations are due to be completed by the end of October 2025 and the shell of the stairwells by the end of the year. The supporting structure consists of a steel construction with stairwells made of reinforced concrete. Where possible, prefabricated components from the Nüssli armoury will be used.
The topping-out ceremony is scheduled to take place in March 2026, just in time for the 95th birthday of German artist Heinz Mack. Full completion of the building is planned for summer 2027.
“We are proud to be realising the vision of the city of Monheim am Rhein together with our partners,” said Udo Baader, Head of Project Management Special Projects at Nüssli, in the press release. “The extension of the Mack Pyramid is not only an architectural highlight, but also a cultural impulse for the entire region.”
