I wouldn't even attempt this without half a box of Polaroid per shot. I've done a modest amount of this sort of thing myself and also did a book on interiors in the Rotovision Pro Lighting Series (with my wife Frances Schultz). I don't know if it's still available but I don't really care as it was flat fee anyway.

Big reflectors are useful too: 8x4 sheets of expanded polystyrene (such as Dow Styrofoam) are ideal, though they do drop 'crumbs' when they're new.
Balancing indoor to outdoor is fun (if there's a window in shot) and is much easier with flash: the interior exposure is controlled solely by aperture, the exterior exposure by aperture-plus-shutter-speed.
Shiny surfaces are of course a bastard and polarizers can be a help but you then need EVEN MORE light.
