    I just watched an episode of Grand Designs New Zealand where a group built a summerhouse (called a 'bach') on a beach. It was a good episode all round with a good bunch of people building a nice small house for not much money.

    One thing that I found particularly interesting was the technique they used to make the first floor, using a system called Click-Raft. This was invented by the presenter Chris Moller and his team and involves sheets of ply cut by CNC machines and then slotted together to make a rigid lattice panel, which is also quite attractive. It can be used to make entire buildings apparently. Here are some links to more information:

    Do we think this will use less raw materials than say a stick built frame? Is it more energy intensive to CNC plywood rather than use standard timber sizes?

    More reading required.

    I think the embodied energy in ply is greater than sawn timber.
    According to ICE
    http://opus.bath.ac.uk/12382/1/Hammond_%26_Jones_Embodied_energy_%26_carbon_Proc_ICE-Energy_2008_161%282%29_87-98.pdf
    Ply has an embodied energy of 15 MJ/kg and general timber has 8.5 MJ/kg.

    I went to see the man that make furniture from CNCed ply today. He was involved in architecture before he took up furniture design.

    Was there not a house on Grand Design that was made from machined ply a few years back. Seem to remember that it used screw piles as the foundation.

    If you are interested in plywood cnc housing check out https://wikihouse.cc/

    Its still early days.

    There is another related one for furniture https://www.opendesk.cc/

    All you need is access to a CNC machine. All the designs are open source.

    I've seen that wikihouse before, looks good. I'm just not convinced yet that it's better than stick built. Is it faster, cheaper or have less raw material used?
