The serrated profiling of the coloured concrete plinth blurs the seams between the precast panels. The facades of the upper floors are made of brick laid on site and over-jointed. Photo: Kalle Kouhia

The three-storey high dining hall is surrounded by a meandering interior space, clad in brick. A glass wall supported by white concrete columns brings natural light into the centre of the building. Photo: Kuvatoimisto Kuvio

The lobby areas on the upper floors offer views of the dining hall through interior glass walls. Photo: Kuvatoimisto Kuvio


The stage in the multipurpose hall also serves as a music classroom. Photo: Kuvatoimisto Kuvio

The school’s street facade and narrow northeast wing continue the rhythm and scale of the listed slab block buildings. On the right in the photo is the Posteljooni residential building (2017), designed by Anttinen Oiva Architects. Photo: Kuvatoimisto Kuvio
