Public Sauna and Restaurant
There is a rectangular box containing warm spaces that is covered with a free form wooden "cloak". There are sheltered outside spaces in between. The lamellas function like venetian blinds and block the views from outside. The structure protects the building from the harsh coastal climate. It shades the interior spaces and helps to reduce the use of energy to cool the building. Moreover, the stepped cloak forms stairs to climb on to the roof and look out terraces on top of the building.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
With Loyly Helsinki offers foreign visitors a public sauna experience - a must when visiting Finland. The building was designed slim and elongated so as not to cut the narrow park. The volume is kept as low as possible so that it doesn't block views from the future residential blocks. The sauna is developed into an easy-going, faceted construction that is more part of the park than a conventional building. When the wooden building turns gray, it will become more like a rock on the shoreline.
OPERATION / FLOW / INTERACTION:
There are three different saunas that are all heated with wood including a traditional smoke sauna without a chimney, a true rarity in an urban sauna. This is how you can experience all sorts of Finnish Loyly during a single visit. You can swim in the sea and in the winter there is an avanto, the hole in the ice for winter swimming.
PROJECT DURATION AND LOCATION:
The design started in 2011 and the construction in 2015. The sauna was opened to publick in May 2016.
FITS BEST INTO CATEGORY:
Architecture, Building and Structure Design
PRODUCTION / REALIZATION TECHNOLOGY:
The cloak is made of Nextimber, a special heat treated gluelam that is pressed to modify timber’s properties and freeing from need of surface treatments needing a lot of maintenance. There are around 4000 planks, more of 2000 of which have individual shape, that were modeled and precisely cut to individual forms by a computer-controlled CNC machine. The cloak has an interesting load bearing steel structure as the beams meet in different angles.
SPECIFICATIONS / TECHNICAL PROPERTIES:
Gross Area 1071 sqm (without covered space under the cloak)
Terrace area 1510 m2 + roof terrace 249m2 + look out terrace 58 m2
capacity restaurant 150, terrace 300, sauna up to 96
Total cost ~6,0 m euros

We made several full scale mock ups to test the exact dimensions of the cloak and how it should be lit. We also tested several different wood materials to see how they are aging in harsh climate. It came out that some more common sustainable impregnation methods didn’t work with our dimensions and we finally found the Finnish start-up company Nextimber that modified left over wood to produce long lasting timber material that doesn’t need any surface treatment like oiling.
The idea for Loyly came from Helsinki city but it was not easy to find a client for the project as running public sauna is not very profitable business. Twice our client withdrew and we had to find a new client. Also the site changed twice and the project took six years to complete even though it is not very big in size. Only when Antero Vartia and Jasper Paakkonen took the project over and got a bank loan of more than 6 million euros, the building works could start.
