Kevin McCloud and Greg James sit down with blank canvases to design each other's dream homes on the set of Grand Designs: Deconstructed. Kevin sketches Greg a minimalist Scandi space with an exercise staircase and a room for his dog Barney, while Greg imagines Kevin's house complete with a motorised Swedish chair, a rotating library, and a Vulcan bomber sofa. Hilarity ensues as their artistic abilities prove spectacularly questionable.
