My proposal offers a very Simple and Unique design considering the available Constraints. A wood theme colour is generally used. the Entrance into the room is through a small cozy lobby which leads you through an opening to the master bedroom or the through a barnyard sliding door into the Bathroom. The Toilet is separated as requested.
The is a His and Hers Closet behind the bed, which is placed in such a way that you can enjoy beautiful views from all sides of the windows.
Thanks for the offer. Hope this Meets your requirements, and if you require more Modifications, its possible.
