Yasmin, is the room regularly used for large gatherings where everyone is in the same group, as it were? I'm wondering of course about the positioning of the long row of chairs, and whether the space can be broken into separate seating areas or not, in terms of the way it's used.

Secondly, I get the impression the one wall is almost entirely window? Could you possibly provide a picture of that wall and the one with the chairs? For the window wall, take the picture at night, perhaps, as it doesn't look as though the curtains will block the light enough -- I'm not sure there are curtains.

Before giving any advice, it's always best to know the function of the room and the amount of people it will generally occupy. The next step is to get an idea of the client's taste and budget.

If you don't need to seat so many people, it's best to start by removing some of the sofas and chairs. It looks as if you have three sets of living rooms in there at the moment. Are you living in the house as well?

They all appear to be equal in size from the photos. You may need to evaluate them and decide which pieces you like best and work with those.

Here's what you can do. Try grouping the largest sofa with 2 chairs together on the far end of the room. Then, towards your adjoining room, make an arrangement of 4 chairs facing each other. Pull all pieces closer in away from the walls. You're going to need some rugs to bring these two groupings together. Try to post photos of that once you've tried it.
