Timber, steel and concrete in sustainable interaction
The building is designed as an hybrid structure where timber, steel and concrete work together according to the strengths of each material. The walls are constructed in CLT (cross-laminated timber), while columns and beams combine glulam timber and steel. The floor slabs are made of prefabricated concrete — a choice that offers advantages in terms of fire safety and acoustics while freeing up more usable floor area. From the outset, the ambition has been for timber to define the atmosphere and materiality of the spaces — not only structurally, but throughout the entire architectural experience of the building.

The decision to combine materials is driven by functional and climate-related considerations rather than aesthetics alone. The building meets Energy Class A according to Swedish National Board of Housing requirements, and rooftop solar panels reduce operational energy demand. Altogether, the town hall achieves BREEAM-SE Outstanding certification — the highest level in the Swedish certification system.

“Enköping Town Hall is a clear example of how timber as the primary building material can give a building both character and low climate impact, without compromising functionality or workplace quality. We wanted to create a place that feels equally welcoming to a citizen visiting the municipality once a year as to someone working here every day. It is in that balance that architecture can make a real difference,” says Sara Nilsson, Lead Architect at C.F. Møller Architects.

A Long-Term Collaboration
The project was realised through close collaboration between C.F. Møller Architects, Skanska and Vacse. As client, Enköping Municipality has driven the process with ambitious goals concerning sustainability, workplace quality and public service — ambitions that have shaped the building from the earliest programme phase through to completion.

“Aesthetic quality in harmonious combination with functionality and sustainability — a project that leaves you wanting more,” says Fredrik Linderbog, CEO of Vacse.

The result is a town hall that combines low climate impact with open and flexible environments for both employees and residents, while simultaneously adding a new architectural landmark to the urban fabric of Enköping.
