Logan Homes 
Franchises throughout Australia and South Pacific. Generally known in Australia as Logan Homes.
An early version of prefabricated expanded polystyrene sandwich (EPS) panelling was a key element of the modular system in the Logan Homes (refer image 8), used for walls and ceilings.

Ceiling panels were solid sandwich panels of AC sheeting with a polystyrene core. Wall panels were AC sheeting attached to metal frames requiring polystyrene batts to be inserted.

Later designs from the mid-1980s saw the AC sheeting layers replaced with non-ACM fibre cement sheeting.

Marketed as a quick and cheaper housing alternative, which was cyclone proof, able to be constructed by a ‘handyman’ in weeks. Attractive to buyers in cyclone-subjected locations.
