When: 17th November 2022, all-day conference

At the conference ‘Building from Buildings’ the real estate and construction industry will meet to discuss and work with innovative solutions needed for the transition to circular economy.

We will listen to inspiring talks about how to enable sustainable practices. 

We will share the latest results and learnings from hands on pilot projects reusing heavy structures in Sweden and our neighbouring countries.

You are invited to take part in innovation workshops, networking possibilities and learn about the latest development within the real estate and construction industry.

Early bird offer includes a site visit to one of the pilot projects in Solna municipality on day 2.

Target group
Stake holders in the construction and real estate value chain. 

Everyone interested in how to build from buildings, making the construction sector more sustainable.

The conference is organized by the collaborative innovation partnership “Återhus – att bygga hus av hus” that consists of 14 organizations representing the value chain of the building process. Our goal is to integrate large scale reuse of heavy load bearing structures in new construction. 

The project is funded by Vinnova, Sweden’s Innovation Agency.
