garden pod building featured in Channel 4's Home of the Future (or the dedicated site here) and we're indebted to Colin Shelbourn for tracking down the maker/model, an AirClad from Inflate.
It's largely built using engineered plywood joists which carry an inflated membrane fixed to the frame using an aluminium extrusion. "The plywood joists have engineered spacers that once the cladding panels are inflated, are compressed with the whole structure being held together and cross braced by the inflatable panels," they say. "This basic building system makes for a water tight shelter." The whole thing can be taken down and moved easily or kept in place permanently. No foundations are required. Lots more technical details here.
