I don't mind the current colours although a greys and beiges tend to suck light out of a room, a brighter colour rather than just white will help. I agree with much of what Jill says above, with a few tweaks ... the lighting needs attention. The room needs some interest, colour and texture to create depth. Get a larger rug, more colourful, with organic pattern which draws the eye outward. Big enough to sit the furniture on. Pick up some of the colours from the new rug and get some cushions. A couple of plants would help with texture and add life to the room. I know you are using the mirrors to add light and space but the one under the stairs is just reflecting the underneath of the stairs ... try a colourful print of a pathway between trees for example, to draw the eye beyond the room otherwise it's a bit bland. The TV is just on a stand that is too small and a bit low, go for a wider piece or try positioning the unit against the other wall in that same corner so it is facing the sofas, then the TV won't look so out of balance. If you make the room a bit livelier and interesting the light issue won't be such a problem. Consider pale turquoise walls for example rather than just white and add some artwork.

Have you looked for a vintage corner unit? Or perhaps a wooden one that you could get a glazier to cut a piece of mirror for?

I wondered where this post had disappeared to. I had a couple of thoughts, though partly covered above. I agree that circular mirror would avoid avoid accentuating the asymmetry of the wall. I would center the mirror above the washbasin with something else to the right, such as the two mirror photo that kikiamack posted. I definitely think a mirror is required, either for shaving or for make-up. I also wondered if you could get the vanity the other way round. I.e. with the narrower end by the bath. I can't totally visualize it, but just think it might look better that way. As for the original post, yes, there are one or two (or maybe a couple more) Pros on the US site, whose behavior is distinctly unprofessional. I think they see themselves as 'a bit if a character' and substitute ignorant rudeness for when they lack an answer to the question that is actually asked. I'm not a pro by any means, but I can see how the design might look unusual. However, I would start from the premise that the room is designed around an owner's specific requirements and not to please people who can only follow the current rules. Be grateful that you have your own site where you are free of their sneering!.

Ha ha! Of course. I attach the plan. I spent a LOT of time thinking about the layout - you’ll see that some Houzzers helped me from my previous posts! Happy to answer any questions about the final logic. The cabinets are from unitsonline.co.uk, Barnes, from the Burbidge range, in soft grey and pale navy. DH installed them. Worktops are unistone Bianco Misterio, from Mayflower Stone. Appliances are all Smeg, with the exception of the wine fridge, which is mQuvee.
