in Essen

The listed Marienkirche was already closed and deconsecrated in 2008. It was then used as a warehouse and clothing store for the needy. A long-term use of the church is now to be made possible by converting it into a residential building. With the help of a wooden construction inside the church, twelve condominiums with 50 to 150 m² of living space spread over three levels have been created.

Fan-like beam structure
in the Marienkirche

Inside the church, a third row of glulam columns was added to the two existing rows of columns. The columns were connected by glulam beams.
A fan-like beam structure has been created in the semicircular choir room. The columns and beams were anchored by various connectors concreted into the existing structure.

The advantages of wood
in the Marienkirche

Since the roof could not be opened for reasons of monument protection, all components as well as the necessary construction equipment could only enter the building through windows and doorways. In addition, due to the extremely cramped conditions, it had to be ensured that the building could be assembled inside. The construction had to be precisely adapted to the existing structure and anchored there.
The low weight of the wooden components as well as the precise and flexible adjustment possibilities facilitated these challenges enormously.
