Hello, I feel that you can design this bedroom by having 1 opaque wall at the back, and 3 transparent walls using glass & steel or glass & wooden french doors. The walls should be white, with minimal accents of blue or green, use 2 layers of curtains with sheer, and brass hanging lamps. All doors can be white PU paint. Waterproofing this bedroom will be essential, so make sure you have sealed all joints and surfaces, with a minimum of 2 feet roof overhangs. Hope this helps! G

Hi Idsshyam, For beige walls, white tiles/marble are a classic pair. This gives you a blank canvas to work. You can also go for darker wood tones such as mahogany or ebony flooring to contrast the lighter wall colour. A cool-tones beige would also complement maple, birch or walnut wooden floors. These can easily bring a contemporary look to your space. Hope this helps. Good luck with your home design.

the sink should be at 33" from the floor. your countertop height will depend on if you're using a top mounted or insert sink
