B2B modular buildings - completed works


Turun Puubyygeli consists of two prefabricated apartment buildings in the city of Turku and was completed in collaboration with NCC Suomi Oy.

The project includes 70 apartments in total (44 in one building and 26 in the other), and has 2232 m2 of living space.

The whole project was carried out closely following the Finnish moisture safety guideline ‘Kuivaketju-10’. These guidelines concentrate on 10 main hazards in regard to moisture. Mitigating these risks leads to cutting more than 80% of the costs related to moisture damage.

In order to complete the project as a subcontractor of NCC Suomi Oy, we passed a quality audit. This permitted us to become an official NCC subcontractor and supplier.


The first Astel Modular project in Stockholm consists of terraced buildings. The project itself has:

  • 18_34 – a building of 6 terraced apartments
  • 18_35 – 18 apartments. Not a completely standard modular building, because the middle of the building is built with wall elements, not complete modules.
  • 18_37 – a building of 7 terraced apartments

The total volume of the project was approximately 2000 m2. It was completed, in three stages, in under a year, and handed over to the client in the summer of 2021.

Fäboden, Stockholm

A new apartment building has been completed in collaboration with Andersson Company Byggnads AB, meeting the ‘Miljöbyggnad Silver’ standards for environmental construction. The total area of the project, which consists of two buildings, is 5500 m2.

The first two floors of the five-storey building feature solid concrete construction, while the other floors are constructed of prefab wooden frame modules, which has led to a slightly longer installation period than usual.

The developer, manufacturer and construction company care deeply about the living environment of the building and the wellbeing of its inhabitants, as well as being fully invested in tackling environmental issues. This is reflected in the fact that the new apartments meet the requirements for the Mijöbyggnad Silver environmental certification.
