Constructing, delivering and erecting the log frame for the 190-square-meter sauna located on the island of Lonna, outside Helsinki, has been one of our biggest and most demanding redevelopment projects. For the sauna, we logged 166 cubic metres of high-quality wood from Central Finland. The diameters of the largest tree trunk stems were up to 70 centimetres. The construction project was carried out in cooperation with a Finnish top-of-the-line architectural agency OOPEAA.
“The Lonna Island sauna is built masterfully. It is hand-carved from unprocessed logs.” – Anssi Lassila, Architecht SAFA, OOPEAA

The log frame of the Lonna Island sauna is protected by an external plank cladding.

The walls of the dressing rooms have been hewed with an axe.

The walls have been hewed skilfully. The axe-carved waves continue in a consistent line from floor to ceiling.
