This system is called ICF (Insulated Concrete Form) which is basically a hollow polystyrene wall block or formwork (which act as insulation) that are concrete filled, giving you a strong & highly energy efficient wall.
The inside of the home needs to be 'drylined' in gyprock (you cant use sand/cement/plaster on this system)
The outside can be clad, or rendered using a 3 coat acrylic texture system (with a layer of mesh inserted into the 1st coat). Dulux provide a texture system for these types of wall.
