Extra Fast Construction In Wood You Believe It?

Metsä Group’s new visitor centre in Äänekoski, in Central Finland, is a prime example of fast construction using wood.

The 1,000sq.m building showcases how Metsä Wood’s Kerto LVL products enable fast, light and green construction. The building combines industrially manufactured wooden elements and architectural solutions with detailed carpentry.

The wooden column and beam frame of the building and its prefabricated wall, floor and roof elements are made from Kerto LVL (laminated veneer lumber) products. In the building, the wooden materials and many construction engineering details have been left visible as part of the exhibition.

Metsä Wood’s wood products have also been used in various ways in the visitor centre’s interior design and visual solutions.


Prefabs sprout

The wooden frame and elements for the Pro Nemus visitor centre were supplied by a Finnish company, VVR Wood. Metsä Wood’s Kerto LVL products where used for the frame system and also to produce the multiple-glued columns and beams.

Sweco Finland Oy was responsible for the structural engineering of the visitor centre.

All of the wooden element models used in the design of the centre had been used before in apartment and hall building projects.


Seven months

Pro Nemus was built in Äänekoski in just seven months. The tight schedule was the greatest challenge during the project, in which architectural details needed to be implemented with exceptional precision. Good planning and cooperation between the various parties played a major role in the implementation of the project.

“Construction using wooden elements is fast and efficient, and project management is easier when structures consisting of elements are increasingly completed at factories,” said Tero Vesanen, MD of VVR. “Metsä Wood’s Kerto LVL products were delivered to the element factory cut to our specification, meaning that assembling was highly efficient at our end.”


Wood faces

The wall elements and the special CNC machining of wood products for the building were completed by Punkaharjun Puutaito, a subcontractor of VVR.

The lower spaces on the ground floor have impressive suspended ceilings with Kerto LVL S-beams. Tthe entrance lobby has coat rack fixtures made from birch and spruce plywood. The wall surfaces with translucent black surface treatment are made from spruce plywood.


Bogs from logs

The cubicle walls and sink furniture in the toilet facilities are made from Kerto LVL.

The stairway walls have birch plywood panelling, with CNC-machined patterns that improve the acoustics.


A building like the forest itself

“This building combines industrial wood construction with a high level of detailed carpentry. This is just what is best about building with wood: the material itself creates opportunities for many types of processing, which are easy to implement,” said Ulla Passoja from UKI Architects, the project architect.

"The Pro Nemus visitor centre is a completely new kind of forest experience. By building an exhibition space that combines pure nature with virtual reality and experiences in conjunction with the new bioproduct mill, Metsä Group wants to lead the way and establish itself as a strong forerunner of the bioeconomy."
