Metsä Portti: Metsä Group's headquarters in one of Europe's tallest wooden office buildings

In November 2026, Metsä Group will relocate its headquarters to Keilaniemi, Espoo, Finland.

The new headquarters, known as Metsä Portti, will accommodate approximately 600 Metsä employees. Metsä Portti brings together Metsä’s forest-based identity, modern wood products and advanced construction solutions under one roof. The building incorporates Metsä’s own wood products throughout its structures and surfaces.

Finland’s tallest wooden building

Metsä Portti is in the Finland’s tallest wooden building, that has 14 floors and reaches a height of approximately 57 metres. 

The building is also among the tallest wooden office buildings in Europe. Its design combines wood, concrete and steel to achieve high technical performance, efficient construction and long-term durability.

The building is owned and developed by Varma. Architectural design was carried out by ARCO Architecture Company and the main contractor is Jatke Toimitilat Oy.

Hybrid construction combines wood, concrete and steel

The new Metsä headquarters is an example of hybrid construction.

Hybrid construction does not position wood, concrete and steel as competing materials. Instead, each material is used where its properties provide the greatest benefit in terms of structural performance, construction efficiency and overall project costs.

The building’s load-bearing structure is based on a column-and-beam frame, reinforced by stairwells and elevator shafts. The intermediate floors use timber-concrete composite structures. A significant portion of the frame, façades and roof structures were prefabricated as elements, helping to improve construction efficiency on site.

Metsä’s products throughout the building

The extensive use of wood and wood-based materials was one of the key reasons for selecting the building as Metsä’s new headquarters.

Metsä’s sawn timber, plywood and Kerto® LVL products have been used in both structural applications and visible surfaces throughout the building. The hygiene solutions of the building are by Katrin.

Examples include:

• timber-concrete composite floor structures
• timber roof structures
• interior cladding panels
• partition wall structures
• timber façade cladding
• terrace decking
• interior staircases
• parquet flooring
• selected furniture elements

The project demonstrates how modern engineered wood products can be used in demanding office, commercial and public buildings.

Carbon footprint and environmental features

Thanks to the extensive use of wood, the building’s carbon footprint has been estimated to be nearly 50% lower than that of a comparable building constructed entirely from concrete.

The project is targeting:

• BREEAM Excellent certification
• WELL Core Gold certification
• Energy Performance Class A

The WELL certification places a specific focus on occupant wellbeing and user experience. The building also includes a green roof and solar panels.

As part of the fit-out, existing office furniture is being refurbished and reused wherever possible. This reduces the need for new purchases and lowers the environmental impacts associated with furnishing the new headquarters.
