Återhus has developed a process that makes building from buildings possible. The process serves as a basis for informed decisions and is a step-by-step guide that ensures the quality of re-used construction elements.

Innovative solutions throughout the process have been tested and confirmed in four real life projects – our ‘Pilots’. In today’s presentation you will hear the Pilot project managers share their main findings and results. Welcome!


Introduction: “How to build from buildings”

Pilot Case 1: Parkhuset – “Quality assurance and permit processes”

Pilot Case 2: Hållbarhetshuset – “Deconstruction method and re-use in
new construction”

Pilot Case 3: Forma – “Waste hierarchy strategies in circular building”

Pilot Case 4: Hugin – “Building block strategy and re-use typologies”
