Charred exterior cladding for a wind farm visitor centre

Story

In Yli-Ii in North Ostrobothnia, the Pahkakoski wind farm maintenance and visitor centre is a building where function reads as clear form. The roughly 700 square metre complex brings under one roof a maintenance hall and offices plus visitor facilities with space for meetings, accommodation and sauna. The centre serves as the wind farm’s maintenance base and storage and as a venue for stakeholder meetings and staff visits.

On the facade, light stone wood and charred wood create a strong contrast that fits the northern landscape. The light part keeps the whole light and the scale calm. The charred cladding backdrop gives the building structure and shelter. The character is reduced and practical but with architectural precision. Surface and rhythm make the building recognisable without it drawing too much attention to itself.

As reported in Ilmattaren, charred wood was chosen for the external walls for its ecology and properties. The material is Finnish pine, and the choice was also about longevity in variable weather. The charred surface withstands moisture, UV radiation and weather variation, which matters in a building that lives with heavy everyday use.

The project is also an example of local focus. Construction started in June 2024 and the centre was completed in February 2025. Partners were chosen from the region, and the aim was to deliver the project with local capacity and ecological choices. It fits the character of a wind farm, where energy production and responsible building go hand in hand.
