Another option would be to develop designs for the canteen area.
The current canteen lacks charm and cosiness (besides its blue colored walls). Designs for lighting or table, desk, chair, bank or bulleting board etc. could help to change this space to a more child friendly environment.
It is important to design something useful and friendly for the school because the children will meet with design in this ages and may be in a first time. And also there is a need to support their places with design in a more friendly way.
