Untreated wood, a saw mill, a flip chart for the project planning and a lot of tool equipment for the installation. The job is building a wodden hut for a social benefit. Looks not easy? Right! Now most wanted are the strategist and planner in the group! How many shelves can be sawed out of a trunk of a tree? How to build the roof? Is there a door? What about the time schedule? It is not the mechanical skill wich leads the group to the goal. Building a complete and complexe wodden hut in a permitted time needs more than men power. The group will learn many aspects of team work, perseverance and systems for optimisation.
