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.

I think the shelves would be better as there's not this huge room taking up space. What did you end up doing?

When I was looking at systems for the kitchen that I have just put in nearly everyone told me to keep away from pull out pantry if for general use. The reason being that get too heavy and do not work properly. I have underbench pull outs for oils and spices etc. and that works well but you can feel the weight in it. All of my food items except opened bottles are in drawers including cans point their sides and I am very happy with how it functions. I do not have any pantry.

Great use of space and creating more storage space through the entire kitchen - Love the white and wood finish through out!
