Other Houzzers are great at furniture placement, but I wanted to note that you really should have seating facing the fireplace and/or the t.v.

Hi Catriona - exciting! Do you have any pictures you can show and preference of colours?

I agree, blinds, they are large windows so that is a lot of material / expense if you go down the curtain route, plus curtains may block out light. We have sliding doors like yours and have chosen to keep them free of any covering, however we are not overlooked. You might also want to consider translucent / sheer roller blinds which offer moderate privacy yet still retain a degree of visibility. We have them on our front windows for privacy as we are in a single storey house / bungalow, people can't see in (during the day) but we can see out. We also have curtains with them in the sitting room as we wanted it to be more cosy / private at night. In the other rooms we have another blind that sits over the sheer blinds, but this wouldn't work for all windows.

We recently put on an extension to our kitchen and although I'm not so much having trouble picking colours for the walls there, I do however find it difficult to match up the dining and living all of which are open plan .. the sofas in the living area are removable covers, one set taupe and the other set white, no problem there but my curtins were expensive and I'm reluctant to change them at the moment so really want something to tie everything together ..they are autumnal in colour ...I'd appreciate some advice on paint colours for the walls they dont have to be the same but would have to tone well together ..Thank you
