At least that's what 'Twirl' has to say. ALL ideas are welcome on the Forum!!!
This idea, too, is far from the norm, but with a little imagination it might prove worthwhile (although I'll probably get flamed by the regulars).
So anyway here goes, the idea is to paint the joists and sub-floor and 'housewares' in the joist cavities, and install a plexiglass ceiling right to the joists? Then you and your friends can hang out in the LazyBoy's Reclined Position (beer in hand), and ooooh and aaaah at the job? It's a weird picture, but might work with some thought. Anyway that's my $1.00 worth.
PS: I've seen this idea in some bars and warehouse-type restaurants except there's no plexiglass. The ceilings are really high and you just see all the 'guts' of the builiding up there - pipes, duct work, and all - painted the same color.
