With wooden pallets and blue paint at the ready, an intriguing building project is under way in Norwich's Chapelfield Gardens.
The Bureau Detours company has set up the Dennis Design Center in the city park, and throughout this week everyone is invited to join in the fun.
Based in Denmark and Norway, the company has previously created unique installations with the help of local people in places across Europe.
When asked what they planned to create in Norwich, Bureau Detours artist Alexander Muchenberger said: 'We are making a billboard factory and we will be taking the billboards out around the city.
'Just come and say hi and find out about the project.'
People can get involved in the Dennis Design Center from 12pm until 6pm each day until Sunday, May 22.
The finished creation will then be in Chapelfield Gardens until Sunday, May 29.

The Dennis Design Center is part of Norfolk & Norwich Festival's free outdoor programme of events sponsored by Tarmac.
