Hi. I would also paint the shelves in the wall colour, unless the shelves are a thing of beauty or in wood, I'd personally want the objects to stand out. If they're done in the wall colour they also shouldn't make the room feel smaller

Let's not forget the wonderful Parker Knoll sofas! They have a huge range of quality, well made sofas and chairs in both traditional and modern styles. So comfy! I have two myself and the large two seater cost approx £1300. The feet also can be removed making delivery a bit easier if you have a narrow hallway like me. Go on their website to find a local stockist, and I've noticed Furniture Village always have a few in store. Good luck!

Love the wallpaper, very classical. Is this a patio door opening to the garden? How much natural light does the room get? These factors influence your choice of fabric eg if u get a lot of sun don’t get a silk material as the sun will damage it. If you don’t get a lot of sun go for a fabric that will help bounce light around eg something with a sheen. Get a fabric that doesn’t ‘bunch’ around the door otherwise it will get in the way as you enter and exit and get tatty. Think about the curtain fixings and the space available above the door and window. Think about the headings you like. In terms of colour, cream and beige are neutral colours (but be aware whether they are cool or warm shades) so you could compliment with colours blue-violet, red, cool blue green - if u buy a colour wheel from amazon (very cheap) you will see how best to pair colours. As curtains are expensive, buy these first and then choose accessories like mirrors as black is a statement and you need to be confident the colours will be complementary. The curtain factory in Finchley London used to offer good bargains. Best of luck.

The colour of the wall paint will depend on the amount and direction of the sunlight and will change when the artificial light is on and even on a different wall of the same room. I’d go for a cooler greyer tones. However be aware some greys can look greener with different lighting. Choose some samples, paint them on a large piece of paper and hang them in different walls of the room, look at them during the day and evening. You might find out that you like whites and greys with yellow and red undertones more. The blue pieces are very nice and will go very well with your light brown sofa It’s a very nice rug. I like the Middle Eastern style. I’d go for a bit darker blue to go with your blue pieces. https://www.carpetright.co.uk/heriz-oriental-medallion-blue-rug#0 Then you can compliment the rug with more Turkish motif curtains https://www.hillarys.co.uk/inspiration/edgy-geometrics/ https://www.hillarys.co.uk/inspiration/edgy-geometrics/?products=Curtains&fabricgridfilter=true&page=2/
