Happi is a multi-use youth centre in Sörnäinen, Helsinki. Situated in an old office building it´s facade lacked the elements of unity and visual features to communicate about the content and activities inside which take place throughout the whole building.

The design consists of shapes found in graffitis painted in the stairways of the building. Enlarging and re-arranging these elements the final, giant composition was designed. The stickered pattern also works as a “curtain” on the lower floors: allowing passers-by to see the lively cafe and workshops inside, but also preventing some sun light and straight gaze from the street level.
