Doing a reno on the PPOR to create two separate teenager living areas. Each of the areas are about 3 metres by 10 metres and will be their bedroom, study and TV area. There will also be a shared kitchenette between them. The ceiling is rack from about 2.7 to 2.2. Looking at ways to best utilize the space - especially as they are quite narrow. I came across the "hidden" beds where the desk converts into the bed - they say you can leave a cup of coffee on the desk and it just swivels and the bed and then back out without moving. Does anyone have experience with this type of furniture ? It would make a big difference to the room layout if it work well. Any other suggestions for better utilizing space (already using the old sofa bed for visitors) ?
