Hi Ali,would it be possible to post a photo?

I completely agree with you, large spaces are slightly intimating to decorate but it can definitely be done. I would first suggest you think of a colour palette to stick with before looking at furniture. This makes it so much easier than jumping backwards and forwards between complete different colours. It can get a bit confusing after a while. I would suggest making the dining room/reception room one whole dining room. You could have the dining table closer to the patio doors with long, draped curtains around the patio doors. Tall lamps, modern book shelves filled with minimal home décor pieces and ideas like that can fill in the corners and give it that homely touch. For the lounge you could have a long corner sofa in the left corner and the TV by the window area. Colour palette wise, I would think about perhaps taupe, mocha brown, black, white with your carpet colour. If you want something brighter than teal/navy would also be a nice finishing colour. It all depends on the style you would like for the room as well.
