How to arrange my living room? Hi, I live in an asymmetrically designed home. The whole home raises in levels which ascend and I have 5 levels altogether. Too look at it from the top level you see half walls on triangular angles descending downward to the final floor level which is a sunken living room. This living room has driven me nuts for two years. I change it all the time because it just doesn't "work" Is there anyone that can give me some help? It has no walls to decorate on! The North wall has a large wall to floor window space that takes up one third of the wall, then further along is another window, just past two steps to enter the sunken lounge. The southern wall has a door that leads under a stair case and then is indented into a 45o angle for the fireplace to sit in. That wall continues along after the fireplace and is solid brick. It has the width of a student desk of wall space enough for a small two seater. The east wall has a huge window in it that would serve as a window seat as it is a bay window and very beautiful with lovely gardens outside it. The west side of the living room has no wall at all... it is open completely and leads up two stairs toward the dining table. Moving around the room, in an anti-clockwise direction I have very very little space to furnish nicely as I have no walls whatsoever. I have a 3 seater, 2 seater and a large arm chair. I also have a small white Ikea desk covered with photo frames. My home is modern and architecturally designed. Therefore there are no shelves, mantles, of any kind to 'dress' it makes it hard to decorate. Any help will be very, very much appreciated.

We need seats. I was thinking a corner lounge suite?! I added the white desk to give some colour with the black frames. Curtains and walls, I am afraid have to stay as this is a rental. So I have to work with the colour. My dining room looks warm but far too much timber for my taste. http://thelivingroomquestion.shutterfly.com/pictures/8 (UPDATED LINK)
