These have already been posted on conceptart.org for a few days, but it's been so busy I haven't had time to get them up here yet.
So these are a few views of the living room interior. As with the exterior it owes a stylistic debt to John Lautner's famous Malibu homes. We went through a lot of variations of set dressing, the floor was originally cut stone, the area within the cylindrical glass waterfall/ spiral staircase was originally an arboretum, and there were creeping vines on the balconies (which you can still see in the east view.) The staircase started out as glass, supported by cast aluminum cantelever arms of graded heights fanning out from the glass, but structurally it wasn't feasable, so cast concrete steps similar to another Lautner house's were substituted. It actually makes the center a little cleaner.
Essentially the interior is structurally unchanged from the original sketch though, and came out remarkably well in the final film. All told I'm very pleased with the results, as you can see in a frame from the trailer.
