This is what I would do if I had this space, from left to right, double hanging space between the bay and the chimney breast shelf above top rail, plinth shelf below, storage is always useful. Depending on the depth of the chimney breast you could incorporate the drawers here in front of it, I see no problem in extending this part of the wardrobe out if this still gives you room to walk around the bed, take this up to approx 1 metre high with a shelf on top, because I am male I would then fit a Tv on the wall above with doors that open out and retract back into the unit so your doors aren’t open into the room while watching the tv. If you do not have room to incorporate drawers here then I would put them in the right hand side of the chimney breast as this is the wider section, if you went for this option then above the drawers I would either continue with shelving above or lower the height of the drawers and put in a hanging rail for shirts or similar in height. I’m guessing if there is a lady present you will need space or hanging long dresses or similar so this could go on the far right leaving a centre space in this section for double hanging items. All doors could be made for example a shaker style with cut mirrors in between the borders. Depending on what you go for you may not need to fit the skirting around that part of the room as it will be hidden behind close doors but will depend on the condition on the walls behind it. Hope this makes sense and give you some ideas.
