In 2019, Bygg designed a modular pavilion for the Rijksvastgoedbedrijf, the real estate organisation of the Dutch government. Built with reclaimed materials, including old window frames and a former gymnasium floor, the pavilion became the starting point for a furniture collection with the same design identity.

The Gymnast uses wooden strips from the old gymnasium floor. The coloured lines remain visible as reminders of the previous life of the wood.

In addition to the dark hardwood, the collection introduces simple birch plywood connectors designed on the OpenStructures grid. This grid system was developed to create interchangeable objects within an open platform.

Bygg developed the connectors according to the dimensions of the grid and shared them on the platform.
