A high level of sustainability was a key requirement for our new city hall for Groningen, and our custom façade system is crucial in achieving that. Constructed as triple-glazed modular panels, it adapts to the different sides of the building with various thicknesses of insulating foam, depending on the thermal conditions. Its sharply etched profile also gives the building its signature look.
City of Groningen
Our bespoke facade for Groningen city hall is not only functional: it also gives the building its remarkably sculptural quality. In bright white, with deep-set windows and crisply profiled edges, it creates an intriguing, high-relief effect. Its distinctive looks arise from our use of techniques adopted from both the shipping and concrete industries in order to develop it. As ever, we were happy to apply knowledge from outside the architectural profession in order to come up with the right solution.
The façade combines high strength and a low weight, thanks to the gel-coated polyester that we used to make it. The modular construction, based on large, seamless elements, has a reinforcing and stabilizing effect. We created the panels using moulding techniques developed in the concrete industry. Each moulded panel consists of two thin layers of polyester composite with a layer of insulating foam in between. The panels also include triple-glazed aluminium window frames. The result is a high-quality façade with excellent insulating properties and low levels of maintenance.
