Assuming the door opens fully, I'd be tempted to have it always open and tucked behind the sofa (pull it forward slightly). Or if you need it closed in the winter, just keep it always closed. Then you could stick basically with your layout, with the chairs pulled in and centred more on a large rug

This isn't drawn properly, but it looks to me that you could consider replacing your large sofa with 2 equally sized smaller ones? I'm wondering if you could also fit this type of armchair between the fireplace and stairs angled in towards the room? I'd put a load of cardboard boxes to the scale of different sofas and try walking through the room to see! It looks like a gorgeous cottage

Love the dark grey and the floor. The windows need painting, get rid of the nets and tone those in using a very light grey ( couldn't get your pic light enough - but you get the idea ), and the a matching gunmetal grey for the curtains, to match your wall. The fireplace is the big thing dating the room. So, i'd focus on amending or changing that too.

I want to change general look of my kitchen from dark brown to white or crystal white, but I don't know what option should I choose: 1. buy whole new furnitures what I like or 2. buy a clingfilm and cover old ones? I am wondering option number 2, because I am not sure if furnitures will be look also good in real, I only saw photos "before/after" for instance: Have any of You already done this before? If only You have some experience with clingfilm please tell me would you recommend it? Or is it better to invest more money in a new furnitures?
