Do you want to work with what you already have? Are you able to purchase new items? Do you have someone who can provide carpentry for built ins? Do you have a budget. Will design just be for sleeping area or seating, desks, closets or clothing storage and bathroom? Are girls there long term or temporary?

Hi grekx, Here are some ideas from previous projects of ours. You may find more on our profile and add what you like to your ideabooks. We specialize in ceilings. It would help if you can post pictures of what your area looks like now. In the above picture, there were ducts to be covered, but the owner didn't want to lower the entire ceiling to cover them. Below, the same idea of using curvy shapes, but the duct to be covered was on a wall instead of a ceiling. The designer (Idevoks Design) used printed translucent stretch ceiling material and turned the problem into a gorgeous backlit design feature. Here, the shapes were kept more structured and rectilinear. Here, a drywall bulkhead around the perimeter of the room hides ducts and other equipment, while the printed stretch ceiling in the middle (tray ceiling) is the design feature.

quartz is a man made product using natural stone and a resin material. No sealing and is stain proof. I have had my granite for 10 years. I have never had a staining issue and set hot pots down on it seldom, but it has never bothered it. I've sealed it maybe 2-3 times over 10 years. granite really doesn't stain. So, compared to quartz, they are very similar. It all comes down to what you like the best.

SP if the slope is 3 inches from one side to the other then you are right you will loose close to 4-5 inches just to cover the gap and then any design will take further space. Ceiling doesn't seem high enough so you can have a max of level ceiling and a 1.5 ft perimeter border. Thanks, Nitin Cornerstone Designs, Bangalore.
