The highest timber hybrid building in North Rhine-Westphalia

The highest timber hybrid building in North Rhine-Westphalia is located in the city harbour of Münster. The new office building is named The H7: H for the German word Holz (timber) and 7 for its seven floors.

Sustainability as a programme

Sustainability is at the heart of the design of this timber construction by Andreas Heupel Architects. We were commissioned for structures, building physics and acoustics and helped tackle building permit issues as part of the process. At the time of building, application of the building code in North Rhine-Westphalia foresaw buildings in timber construction with a maximum of three storeys.

Based on our research for the 20 storey Lifecycle Tower, which had already been realized in Dornbirn, Austria, as an eight-storey prototype building, we were able to demonstrate the feasibility and safety of the timber hybrid building and obtain the necessary building permits.

For the H7 project we recommended a timber hybrid construction. With this approach we met all requirements for acoustics, fire safety and structures with simple means. As a result, the timber construction can be experienced inside. ”

Designing with concrete and timber

The underground car park and ground floor as well as the core of the H7 are constructed in conventional reinforced concrete. Additionally, a concrete “spine” features the main service distribution along the length of the building. On all other floors, timber-concrete-composite floors are used. The columns along the façade are designed Glulam.


Considerable carbon dioxide savings

By replacing or supplementing concrete with timber, around one ton of carbon dioxide per cubic meter of timber could be reduced during production. In addition, the timber stores another ton of carbon dioxide per cubic meter. In this way, the use of timber has saved around 262 tons of carbon dioxide compared with conventional reinforced concrete structures.

On all floors above the ground floor, timber-concrete-composite floors are used and the columns along the façade are designed Glulam. On all floors above the ground floor, timber-concrete-composite floors are used and the columns along the façade are designed Glulam.
