Thanks both. At the moment I only have one couch which is the same colour as what is there currently, and a few different rugs in grey and beige colours. I might copy the mirror that is currently there and a similar lamp as I think they look well. Was thinking maybe a clear glass coffee table in the middle over a beige rug? I guess modern would be my preffered style but Im pretty open!

Snan, The bottom oval one in Eskandari's photos would also work in your room (or something like that). The oval shape visually gives height to the room which would work for you as well. I know that shopping around can sometimes be exhausting, but if you were up for the search that would be another option if you're not sure about the round one you have already. I would also look for something that combines the elements of your wallpaper as well as your fireplace (if you are not planning on changing it) in order to bring those together, i.e. try to bring in the color tones of the two.

Please, please, please, don't paint any of the wood. You have a beautiful setting for mid century modern décor. I can agree with removing the carpet from the stairs, however I would just want to add a jute floor covering for the stairs after. The light fixtures should probably both be changed. You even have a lovely roomy space in your foyer. I always recommend starting with the foundation of the room, which is the floor covering. Kilim, ikat, Persian or Oriental would be my choice. I would think minimalist would be very fitting in this space.

Hello Duncan, They are good and I am biased as I don't use companies that don't provide trade discount... as I usually like to help my clients out... Here's a few images and an edging on a runner can be lovely too... I have also included one of a painted stair... So you have an option all of which are rather striking.... : )) x http://www.naturalrugstore.co.uk/coir-rugs.asp?gclid=Cj0KEQjwiKS3BRCU-7XQ75Te3NoBEiQAA2t_xPmcwAZ3TS0Qhq1t1hzYsP-r8oFgdC385qXO88eXioYaAjCE8P8HAQ The painted one... I would include the banister in this scenario..
