Timber Floor
This comprises a prefabricated structure based on an 800x800 mm module, made up of 20x160 mm timbers with notched joints, and at the joint of the four beams the grid is held rigid with a 60x60x160 timber wedge, glued and nailed.

The over-lying floor surface can be timber floor boards or an in-situ 50 mm concrete floor slab, lightened with pumice stone. (Fig. 16)
