Fact Sheet:
Project: Zinc spire
Built: 2014-2015
Client: Jeudan A/S
Type: Conservation and Restoration

Søtorvet makes up one of the main estates along the lakes in central Copenhagen. The complex was designed in 1873-76 by the influential Danish architect Ferdinand Mehldal. It consists of four blocks with spires, arranged symmetrically on either side of Frederiksborggade. Søtorvet was one of the first schemes to be built within the new master plan for Copenhagen which intended to partially demolish the existing mounds framing the inner city to reconnect it with the outer boroughs of the city.

The project concerns the treatment and repair of the timber roof construction of the north east tower of the inner city complex Søtorvet. Furthermore, the existing, later added, cobber roof will be restored to zinc matching the remaining roof surface of the estate.

The existing, later added, cobber roof will be restored to zinc matching the remaining roof surface of the estate.

During maintenance roof works it was discovered that a large part of the timber construction of the
north eastern tower was heavily infested with dry rot fungal growth. Earlier ill repairs had aggravated the situation further by casting a concrete deck around the rafter ends.

The affected timber was treated or replaced and the later concrete deck was removed and the (tagfod) was consolidated with a new steel construction.

In relation to this work, which affects the entire spire, it was decided to replace the existing copper roof. For unknown reasons, the roof surface of the spire has been changed from zinc, while the remaining complex remained with a zinc roof. This was not only historically wrong, but also broke the overall symmetry and cohesion within the complex. Furthermore, the material caused problems with corrosion on the underlying zinc gutters and flashing.
