Let's build in wood, for future generations

There is an urgent need for more schools—at least 15 000 in Europe alone. To find a fast and sustainable solution, we developed an easy-to-build school kit made of wood.

Building in mass timber reduces emissions, shortens construction time, and improves well-being.

We believe this is the way forward—not only for schools but the entire construction industry too.

One easy-to-build solution. A million possibilities.

What is Sylva™ by Stora Enso?

Sylva is Stora Enso’s range of engineered and prefabricated products in massive wood comprising pre-manufactured, custom-made applications delivered just-in-time to the building site.

This solution enables faster construction, reduced costs, more efficient use of raw material and fewer emissions than concrete or steel.

The prefabricated, easy-to-install components respond to the developers’ need to reduce on-site labour, shorten construction timelines, and increase sustainable building practices.

School concept by Stora Enso

This scalable wooden school can be built with a Sylva kit in a matter of a few short weeks.

In a matter of minutes, this school will grow back.

Stora Enso can trace where 100% the wood comes from in Sylva kits. We only source wood from European forests which grow more than they are harvested and is third-party certified (FSC®*, PEFC, or both). 

Sylva is exclusively produced with only renewable electricity or fossil-free energy. Making Sylva by Stora Enso a name you can trust.
