Is double brick still built in the UK, or is wooden framing with brick cladding more common?

Breeze block for the inner skin and red brick for the outer skin is still the standard as far as I see from local housing developments and friends doing extension. Internal dividing walls may now all be stud partitions but wooden structures are pretty uncommon.

It's cut on a cnc router table, which does not handle regular wood very well. The dimensional stability and anisotropic nature of plywood is a better fit for most automated cutting methods. If you try to CNC route most regular dimensional lumber it has pretty bad tearout and splitting unless you use a really fine cutter and go slowly (which takes forever).

> They claim comparable cost as brick/block construction. £230/sqm.

That seems quite unappealing for something with a certified life of 60 years (even if it lasts longer in practice, mortgage brokers won't be keen)

Oh man. To me this plywood stuff seems like it might be marginally more durable than 2x4 and sheetrock, or maybe not (worse ventilation etc). So to me it seems like they have just reinvented the American "balloon" construction system, but overengineered, and probably at much greater expense.
