WOODCIRCLES Concepts

Two key ideas behind the demonstrator
In this section, read and explore two core innovative concepts developed by the WOODCIRCLES project, then answer the questions below related to each one. The bars show, in real time, how visitors have answered, so you can see other visitors’ points of view.

The Urban Sawmill

Timber is recovered and sorted into standardised products ready to be used again:

New urban rule: design for assembly & disassembly

Every new public building must:

✓Use as many Urban Sawmill components as possible
✓Be modular
✓Be designed for complete disassembly so all components can be reused
✓Be capable of changing function after disassembly

Design your city

Designing the second life of public buildings
Read the scenario and the mission, then complete the sections below. There are no wrong answers, we want your ideas and your honest impressions.
1

The scenario

The city of Tartu wants to become a leading example of circular construction. Until now its public buildings — a school, a library, a civic centre — were built as permanent structures, kept the same function until demolition, and then became construction waste. In Tartu's new vision, public buildings are conceived as material banks that can be disassembled, adapted and reused over time.

To make this possible the city has introduced the Urban Sawmill: an infrastructure that recovers timber from demolished buildings and construction sites and turns it into new standardised products ready to be used again — from wood-fibre boards to solid timber and CLT/GLT lamellas for construction.

Your mission

You are looking at the Pilot Demonstrator — a real example of a disassemblable timber structure. Imagine Tartu gives you the power to decide and design a temporary public building of this kind: something usually built to be permanent, but here it will serve one need for the next 10 years, then be completely disassembled and its modules reused to create a second building with a different function. On the next page, tell us what you would build, where, and how you feel about timber buildings that can be taken apart and reused.

The first life, what would you build?

Choose one first function for your temporary public building:

4

The second life, what would it become?

After 10 years the building is disassembled and its timber modules are reused. Choose one new function for the second building (ideally different):

In one line, why is this second life valuable for Tartu?
