A comprehensive renovation project was carried out in this office space located at Mikonkatu 25, Helsinki. The space covers a total of about 850 m² on two floors and is located in an office building completed in 1973, next to Helsinki’s main railway station.

Extensive demolition work had been carried out on the site acquired by the Finnish Bar Association, and the work started with the raw surfaces. The premises were completely rebuilt and the heating, water, drainage, ventilation, cooling and electrical systems were renewed. The work was carried out entirely in-house and Sähkö Sinisalo Oy and U-H Talotekniikka Oy participated in it.

The high-quality materials and different solutions chosen by the client’s interior architect kept the project’s level of requirements quite high. In particular, the large 120×120 cm interior tile used in the project with only 2 mm seams posed special challenges for the foundation work and dimensions. The use of a laser scanner was essential in order to achieve the desired accuracy. The AV and other technology used in meeting and auditorium spaces also require special care in terms of groundwork. Different solutions, such as electrically darkening windows, several interconnected screens and general technology control systems together created a truly modern result.

The total duration of the project was about 6 months and about 20 people worked on it. The client’s project person also actively participated in the progress of the project and we were quite satisfied with the whole.
