Schoolhouse, St. Gingolph

Scale armour made from concrete

The schoolhouse is in St. Gingolph, on the eastern side of Lake Geneva, situated on a prominent slope above a sports hall. It is perpendicularly aligned, meaning its roof is also visible because of  its position on the slope Therefore a uniform material had to be used, turning it into a rear ventilated "tank" made from prefab concrete elements.

The prefabricated concrete elements are arranged in such a way that they look like scales on the roof and facade. Making the roof and facade a single unit, giving the building a certain dynamism. The focal idea behind the shell of the building was to accentuate the mineral structure of the surface. That is why the concrete has been dyed and blasted. The specialists from PSS then coated the highly absorbent surface with faceal Oleo HD for a high-performance impregnation providing durable surface protection.

  • Facade made from prefab concrete elements – protected with faceal Oleo HD oleophobic and hydrophobic coating.
