Wood in the city


The tallest, completely wooden multi storey building in the Finland.

Lighthouse Joensuu is a 14-storey apartment building.The total height of the building is almost 48 meters which makes it the highest wooden building in Finland. It will provide 117 apartments for local students to live in.

At the case of Lighthouse Joensuu, the self-weight of the building was relatively small compared to structures made of concrete or steel. In the beginning of the design process, it was also proposed to have the core of the building made of concrete (elevator shaft/stairway) to add weight and stability to the building. This design option was however cut off by demand by the contractor for construction work to have the entire structure made of wood elements to have an environmentally friendlier option to concrete buildings.

After initial risk analysis with the Joensuu city building control it was determined that the building would be considered as an exceptionally demanding project and the building’s consequence class would be CC3. This would require further risk analysis procedure and the usage of external inspection during the design and construction process. This procedure created demand for enhanced co-operation between project participants. In addition to regular meetings during the design and construction process, it became necessary to hold also additional workshops to go through the design principles, guidelines and demands which the new system of tensioned rods and high-rise wood building would bring to all participants of the project.

Energy efficient wooden daycare canter.

Hukanhauta kindergarten is the first CLT-built daycare center in North Karelia and It was completed in 2018. Energy efficiency is one of the main principles in planning and the building is in the highest energy class (A). Energy efficiency is achieved using wood and insulation but also solar panel systems.

The unique aspect of Hukanhauta kindergarten is that there is lot of visible load-bearing wooden structures and you can really ‘feel’ the wood in the building.


Most modern multi-use baseball stadium in Finland.

Kerubi Stadion is Finland’s most modern baseball stadium, located just one kilometer from the center of Joensuu. The stadium caters primarily to Finnish baseball, but also to concerts and other events.

Wood has been used in the load-bearing material and also as a surface material. The construction of the stadium required 1325 m3 glulam/LVL, 10 km sawn timber, 17,5 km facade lathing and 9500 m2 of plywood and other fiberboard.



Ecological, sustainable and energy efficient multi-story house.

Joensuu Pihapetäjä was the first wooden block of flats built in Joensuu with more than two storeys. The construction method was CLT solid wood elements which helped in reducing construction time. Construction started in August 2016 and the building was ready for moving into in the spring of 2017.

Energy efficiency was the main theme in the planning of this building and thanks to innovative solutions, Joensuu Pihapetäjä is the most energy efficient wooden block of flats in Finland




The regional construction project of 2013.

The first project in Finland in which CLT elements have been so extensively used. Joensuu Elli’s student homes in Noljakka are one of Finland’s largest passive level CLT timber block projects. Wood house area consists of six two-storey houses and the area was completed in summer 2013.



The largest wooden building in Finland after completion in 2004.

The frame of the multipurpose hall consists of 28 almost identical wooden arched trusses, that are connected at the top of the building into a roof light that resembles a boat. Total size of the building is 14 600 m2.

In total, 4000 m³ of timber was used to build the arena. When completed in 2004 it was the largest wooden building in Finland and it got an RIL award in 2004.




Wooden office building with innovative solutions.

At the time of completion, Metla-office building was the largest wooden three-storey wood-frame office building in Finland.

A total of 2000 m3 of timber (around 20 hectares of forest) was used in the construction. Nearly all tree species found in Finland have been used in the structures and interior of the building. As well as 100 years old recycled logs for the outer walls.

The building has won several awards, including the Construction project of the year 2004 by the Senate Properties and the Wood Award 2005 by Puuinformaatio ry.




One of the first large wooden buildings in Finland to be implemented using the platform technology.

Innovative wood school project which was accomplished with The Cuningham Group, an American architectural agency with extensive worldwide experience in projects.
