The student housing organization KOAS, is building new student housing in the city of Jyväskylä, in central Finland. It aims to provide 160 new apartments for students studying in the city.


Student housing in Finland aims to provide affordable rental apartments for students. These apartments come in a variety of shapes and sizes to cater to student needs.

Jyväskylä is a medium-sized Finnish city of 140,000+ residents. The city is home to over 20,000 students in higher education at the University of Jyväskylä and JAMK – the Jyväskylä University of Applied Sciences.

Student housing organization KOAS

KOAS is a student housing organization in Jyväskylä. It currently has 28 student apartment buildings, providing housing to over 4000 students. An increased influx of students into the city has increased demand for student housing and thus KOAS is now building a new apartment building to meet these requirements.

KOAS’s new student housing project – Harju

KOAS’s newest student housing project is set for completion by the end of 2019 and is expected to host its first tenants in December. The project consists of two separate buildings totalling 160 apartments - 136 studio apartments and 24 two-room apartments.

The new apartment buildings’ name ”Harju” is Finnish for ”ridge”. This is because the buildings are located near the Jyväskylä ridge, formed during the ice age. This area functions as a park, and enjoys a great view over the city.

The construction project

KOAS has been building new student apartment buildings for the past few years to meet the increasing demand for student apartments. The KOAS Harju construction project was initiated by its main contractor, Pohjola Rakennus, in May 2018. It is due for completion by December 2019. The construction site is located near Jyväskylä city centre and the Jyväskylä ridge outdoors area.

Centum SC10000 used for bricklaying

The Centum SC10000 is our strongest mast climbing work platform to date. It is designed for heavy-duty facade work and for projects requiring a larger platform size at demanding heights. Its maximum loading capacity with a single mast is 6,000kg with a platform length of 4.1 meters – but with a twin mast setup, its lifting capacity can exceed 10,000kg with a platform length of 15.8m. As can be seen, this mast climbing work platform truly offers fantastic working efficiency.

The project’s subcontractor, Muuraus Nahkala, used the Centum SC10000 for bricklaying work. Muuraus Nahkala chose the SC10000 for this project due to its long reach, heavy lifting capacity and available extensions. As can be seen in the photos and project video show, the facade will be of a light-coloured brick, which blends in well with the surrounding buildings. The construction project also employed two Maxus SC5000s for facade work.

Customer feedback

Muuraus Nahkala’s general manager, Janne Nahkala, has experienced the benefits of using mast climbers before, as in the Attendo Kultakehrä bricklaying project. This is what he had to say about our mast climbers:

They (the mast climbers) make working easier. The working height is better and there is nothing blocking your view on the wall. This way you can access the wall much better and always work at a height of your own choosing.
