Hohe Straße Cologne

An office and commercial building designed by renowned architecture studio caspar is currently being constructed at Hohe Straße 134–136 in Cologne. Werner Sobek is responsible for structural engineering and building physics on this pioneering project in the heart of the city centre.

A Focus on Sustainability and Deconstructability

One key aim for the project is to create a supporting structure that is both sustainable and easy to deconstruct at the end of its useful life. In order to achieve this, the plan is to base the building around a hybrid timber construction made up of a reinforced concrete skeleton frame, a reinforced concrete core, timber ribbed slab floors, timber beams, timber columns and isolated columns.

In line with the city’s goal of providing CO₂-neutral district heating by 2030, the new building on Hohe Straße is being linked up to the local heat network. Recycled concrete is also being used to make the project’s hybrid timber construction as climate-friendly as possible, and solar energy systems and areas of green roof are being installed to make optimal, sustainable use of every available space.
