I recently had a look around the Surf Coast and Great Ocean Road in southern Victoria, Australia. It was amazing to see the size and scale of the walls. The local Surf Coast Council has a large curved feature wall that was 500mm thick that greets visitors to the Torquay and Bells Beach region.

Talking of massive, the RACV resort in Torquay is would arguably be the largest modern earth building with huge arcing walls.  Some walls look 8 meters tall and are atleast 500mm thick!

There would be thousands of square meters of rammed earth with pre-cast panels and loads of internal walls. The building was designed by Wood/Marsh Architects

Finally at the other end of the Great Ocean Road at Apollo Bay we visited this residential building under construction that had 8m high walls and were 600mm thick stabilised insulated rammed earth. Double the thickness of the standard 300mm thich walls.

Just another example of designers going for the chunkier, thicker walls. It really does give the house loads of body and integrity!
