Hi enthudoc, I assume the back of this apartment doesn't have any windows, I usually prefer rectangular rooms, but in this case it's possible to create a 'loft' type bedroom with glass partition that make the bedroom feel more spacious.

Already you have left space for 18mm thk single glass.. to insert inside the hollow gap.. A;so a electrical wires in been kept on top, i dont know how u where u wanna used that for, there is no sandwich type glass space over there... Wood u hav already used for panelling & u r looking for glass.. wat type to take... My suggestion will be, u go for clear toughened glass, so that on one side u can fix film, ,,, so that any time if u feel like to change the design u can. but if u for for designer glass or decorative glass, which will not alter later, that will be one time large investment for u ,,, But changing the film will not disturb the entire partition and glass , only reasonable price u can change the entire film as per latest trendz

HI -- Well this is a nice floor plan but it creates problems . Because the space is all open doesn't mean you have to put the living room or the dining room where indicated on the plan . Also where you have marked for the sofa is not going to work there . Not enough room and in the way of getting to the bathroom etc, I do think you may have to have a free floating TV stand between the living -dining rooms . You could have the TV on the wall beside the kitchen and have the sofa facing or on the left wall and the dining at the front . I would put the TV on the left wall near the entrance and have the sofa facing it , leaving a hallway walking space behind the sofa . It's too bad the front entrance is on the left . If it had been on the right then that would be better flow into the center of the main floor . If you do decide to have the TV room divider where you show on the plan , keep it right over to the left wall as a room divider , then it won't cut the room in half so much and it keeps the stairwell open . Remember , you do not need to push the furniture against the walls .

Since the height under the stair is low you will need to lower the floor area if it is already not built by 30 cm and you could use it as a study area , a computer table or an ironing space . The first flight can be covered and used for storage. If the stair is a metal stair you can design an internal courtyard there.
