I selected Neither - Reason. I think that particular room looks great because a huge amount of expense has gone into making that room picture perfect. It is unrealistic to think that the average home buyer / owner will have that kind of money to invest in a room. Generally I would never put wall paper on a ceiling. The only thing that has made this room work is that they have been able to invest a lot of money into making sure this room is "show room" quality by matching the paper and the carpet and all the furnishings. It is not a homely room. It is a room for a palace or for the rich and famous. You could not relax in this room and I do not think the average family would ever allow their family to use this room - most of us do not have "special occasion" rooms.

Hi, it’s stunning isn’t it, it’s been used at the Hotel Henriette in Paris, owned by designer Vanessa Scoffier I am sure if you emailed them they would be delighted to give you information as to where you can source this beautiful wallpaper, check out the hotel it’s absolutely gorgeous.

The problem is that we have no idea of the rest of your house , whether it is ultra-modern or classical or colourful or eclectic or . . . . . . . With the limited info , personally I'd go for a burgundy and ( narrower ) gold striped wallpaper , or possibly cream and bright sunshine yellow stripes , but then everyone is different . I wouldn't go with anything 'organic' looking , including grass or flax looks , fake timber or any wallpaper along those veins . The grid wall idea isn't a favourite either , but depending on ceiling height , how about doing the lower 1/2 to 2/3rds of the wall like that , then vertical striped wallpaper above that ? Breaks it and makes even more of a feature IMO .
