Felix Arkitekter is a prominent player within the field of restoring and preserving older buildings and using recycled materials for new projects. In 2007 the firm won an award for a project in Pilestredet Park, called Gjenbrukshuset, due to the incorporation of the materials from an old wing at the national hospital, Rikshospitalet. Felix Arkitekter is adamant that the preservation of buildings leads to less environmental damage and that rehabilitating structures into modern use adds value to the communities who live in symbiosis with the architecture around them.
