Your wallpaper might be the best feature for your dressing room and just let it show right through a clear acrylic dressing table.Or you could continue with your touches of gold on a new vanity or by using a bit of gold leaf on an antique one. Add a gold chair to a rosewood vanity to continue with your bedroom look. My personal favorite is #4 ,5 & 6 below. Love the curves and a desk will work too.

A bedroom is such a personal space you should look around for inspiration and really explore your likes/dislikes. Bring your favourite colours and textures into this space and warm it up with some art and accessories that mean something to you.

Would you consider building a closet that would hold the platform on which your mattress would be placed? The outer side of the platform could have drawers or doors to the storage units under the platform. This kind of enclosure would work better for a twin bed than for a double, but it would provide a place where the bed can be concealed during the day time. Then, if you could allow a path between the bed enclosure and sofa, you could have the sofa face the dining table, or you could place the dining table at a right angle to the end of the sofa.

Thanks a lot for your comment. I wouldn't exactly call it a walk in-closet. As you can see from the drawing, Its space provided for two single wardrobe (one on each side). Maximum width can be around 3.5 ft. The humidity point is quite relevant. The question is would it be possible to include a wet room in the space i.e. 6ft x 8.6ft. - considering I don't remove the dress wall. Wanted to get a sense on the possible layout. Thanks and look forward to your advise.
