A group responsible for social housing in Great Britain was on a study trip to Freiburg to explore ecology in the form of environmentally friendly construction. They had various items on the programme, such as a discussion with Mayor Prof. Dr. Martin Haag for Urban Development and Building. Before their journey home, they made their way to Oberharmersbach to see the production of our ecological, glueless solid wood systems NUR-HOLZ. They followed the individual production steps with enthusiasm. Afterwards they visited an already inhabited NUR-HOLZ house and were amazed at the generous living space in relation to residential houses in Great Britain.
