In November 2017, a devastating fire broke out in a property on Biblioteksgatan in central Stockholm, Sweden. The interior of a historic property was completely destroyed, while thankfully the stone façade, inspired by medieval architecture, remained. Work has now begun to build a new property inside the unique 120-year-old façade. The property owner, Hufvudstaden, has hired Polygon Sweden as the environmental coordinator and an advisor in moisture safety in this significant and spectacular project.
