We have been renovating an 80's home with a vaulted roof in the living/kitchen/dining area, something like your picture. We needed to make the space look bigger so we opted to hang our tv from the roof using an Adtec tv bracket in white, pretty nifty unit, all wiring, aerials etc go up the mounting pole and through the roof. The unit also swivels 360 degrees which is great for any view point in the room, including our outside area. We had a tv unit custom built by Jarramar Furniture which is like a rather large floating cupboard. The unit has 2 draws and one cupboard. All the cords etc come down the wall in the adjoining room behind the door, neatly packed into duct and back into the back of the floating cupboard. It's very neat and tidy, keeps everything off the ground and makes your space look bigger. Both Adtec and Jarramar have websites where you can check out their stuff. You just need to ensure your tv weights are ok for the Adtec unit your wish to purchase. Good luck with your design.

Depends on which room it is! If you're spending a lot of time in there, a lighter colour is best because with warmer colours, it tends to bring down the roof a bit if that makes sense - what did you end up doing?

ie is there any benefit in particular to have ceiling white paint?

I'm thinking of using hydrapanel in the bathroom but how do you get jointers to line up on an angled ceiling, When I say that I mean at the ends of the sheet where the ceiling meets the wall (where the fan is as its not a right angle. It's doing my head in, I can't get hold of anyone from the company and can't start till I figure it out. Thanks in advance for any help.
