My office is slightly smaller 12x20. I have 4 cans on a grid in the four corners (roughly 30" out from the wall). With a desk lamp - I have plenty of light. Thinking about a ceiling fan and bed lamps. You should have way more light than you need for a bedroom. If possible switch the 2 cans along the wall (which are your pathway to the bath) on a separate switch and 3 way them to your bed and next to the bath. It sounds like the can above the bath door will work for the outside door as well. You can add a light to reach in closets ((We do a flat strip light mounted inside, over the closet door). Most fans have a handheld remote control. You can 3 way the 2 lights on the opposite wall to the door and bedside as well. With 9 ft ceilings- you won't have enough light for reading, but the table laps or wall mounted lamps will be useful there.

If you love that wallpaper, use it in bathroom. Not really right for behind bed. I would go a drum style chandelier. In a silk pale gold. Your bed looks zen or Asian to me. I love it. But, you don't. Need to much with it. Keep it simple a more formal drape on windows, color would depend on wall color and bedding. I'm thinking a dramatic peacock satin. Use a lighter same tone on walls a rich teal. Ceiling can be gold leaf. With alight that cast shadows on ceiling at night. Then your wall paper will tie in. Furn should be mirrored.

Thank you Groveraxle for the virtual ! you are too good a designer that is why I cannot help troubling you ;) you have your biggest fan in me ever since your first advice:)) As for an in-house designer I am certainly going to call somebody soon . Just that I get such a lot of options and great advice from highly accomplished and talented Houzz designers ..I would be better prepared after these conversations ..please forgive me for pestering you guys like this:)

Referring to the sketch above as option 1 you can have two option, option 1, as obvious cutout at the middle of the u shape staircase, in addition to this you can also have a double height entrance foyer with a chandelier in between hanging from the top. on first floor you can shift the balcony door side ways as mentioned with a circle. referring to the image above option 2 option 2 would be a complete change of staircase orientation , bringing the staircase in front foyer, extending the upper cutout as marked in dotted line, the new found area can help you extend your both bathrooms areas or can help you put some ground floor furniture or a informal study area.(see if your FSI permits to all these changes). and on the top your new area can accommodate your big gym equipment's like treadmill , and some additional gym storage. here you can also get to know from top who has arrived to your front door peeking downwards. further the walls of this area can be decorated while doing interiors and make the foyer look grand & luxurious. option three, If you are thinking of giving a cutout in center of the hall, please avoid, your areas above wont be usable in an appropriate way. cheers
