A belated THANK YOU to everyone who commented. This is the final result. We're super happy with it. Room A north facing "through-lounge" in a new build, 3 bed semi detached house Paint Walls: Purbeck Stone, Farrow & Ball Ceiling: Strong White, Farrow & Ball By the way, the room isn't as long and skinny as it looks in the photos. Painting it all one colour actually made it feel much, much larger. We were really impressed with the quality of advice the F&B staff gave us in regards to colour. We loved Purbeck Stone from the minute we saw it, and being brave really paid off.

The funny thing is that nothing dates faster than the latest trends! Whether it's the recent vogue for Pistachio green, Orange, or neutral greys or taupe colours or trendy wallpapers, such as the ubiqitous 'Woods'. Paint is the safest and easiest option for those without confidence or design knowledge. Paint does bring out the architectural quality and details (that why until recently architects have rejected them on the whole). But I really disagree with those that say paint lasts longer than papers. Of course it depends on if it's used in high traffic areas but wallpapers in some houses have lasted well over a century! A choice of wallpaper show a certain statement of confidence and with current Site specific, carefully designed Digital papers or Artisan designed, hand crafted or printed wallpaper you are installing a work of art to be enjoyed for a considerable time.

As a wallpaper designer I think you know what I'm going to say...Wallpaper, of course! My latest designs (The Joinery Collection) can be mixed and matched on the wall for unique outcomes. This mirrored effect is just one way to go. Check out my bespoke design service too. I can incorporate branding, lettering and photography. www.identitypapers.com

Agree with above comments. If you did use a heavy duty lining paper it would need to be applied horizontally but even then you may get problems of the texture showing through, unevenness at the joins where it won’t adhere because of the texture, bubbles or lifting because of the extra layers, and it might make it difficult to remove later on because of the extra adhesive and paint. I would either paint with a trade Matt paint so the texture is not so obvious or strip and re do.
