See how things are progressing with the green build house. Some solid work this summer has seen the ground slab installed, retaining walls constructed, lower level walls built, waterproof tanking done, drainage underway and the ‘beam and block’ upper floor installed. Some backfilling will be done soon which will show the partly ‘sunken’ nature of the building.
The walls are constructed from insulated concrete formwork (IFC) which gives a vary good level of insulation and which has also helped to form the retaining structure.
The waterproof tanking is stuck to the outside of the IFC and protected with a water draining membrane.
