The old school building in Altdorf has been redesignated as a community centre. In line with the plans drawn up by Prof. Dr.-Ing. Dieter Sengler, self-supporting ceilings made of glulam (glued-laminated) beech were installed. The excellent workmanship was provided by the carpentry business Karlheinz Huber from Altdorf.
