Love the stained glass window. If your planning on keeping it, I would consider pulling colors out of that to inspire the design for your room.

I did ancestral gold from sherwin Williams...would look great in a historic home...I love the color so wanted to pass it on to you

With the slanted ceiling, you can put the bed on that wall. Or it looks like the perfect height for closets that you could run along that wall. Since the stain-glass window is not part or the original house, you could take it out and use it for decoration or relocate it to an area where it will be more of a feature.

The slanted ceiling can be great for a bath if it is aims back to tall for the shower wall and service area, or you can put a shower seat under the slant and put the shower service on the front wall with a frosted glass divider just to the left of the window trim - Try the sink opposite the window wall with the toilet in the back corner where the slanted ceiling will best accomodate seating.

Can you post a floor plan of the space with measurements? Also pictures of other views of the room?
