i can't set my living room. it measures 3.8 X 4 meters, it opens into my dining room so it has only three walls, one wall (3.8m) has the kitchen door at it's end leaving 2.6 meters free after it, the other (4m) has a window in the middle and the third has a balcony door ( 2.5 meters wide) it doesn't have a fourth wall as i said it opens into my dining room. i have one big sofa (2.5 m) and a 2.2 m LCD wall unit. how to organize?
