Choose a traditional style of bunkbeds. On the lower one add a piece of plywood to one side. On the upper one add a piece of plywood to the opposite side that reaches to the ceiling. The room is now divided. If your building skills are lacking you can hang curtains instead. You would have to attack them to the bed for the lower bunk and the ceiling for the upper bunk. Or you can arrange the beds so that they are perpendicular to one another. If you use this arrangement, a dresser or a desk can be placed in the excess space underneath the raised bed. With either arrangement, choose a bottom bed that has built-in drawers for storage. Either choose a theme they both like (outdoors, skating, etc) and paint the walls accordingly; a neutral color is best...or you can paint the walls behind each person's bed in a color that she chooses and make each bed with different linens. Allow each girl select an area rug she likes and place the rugs on their respective sides of the room. If you already have 2 beds in the room put them on the 276m wall right next to each other with a room divider (or screen.) You could put the beds against the walls with 2 narrow bookshelves or dressers (side by side) between them. Have one facing toward one bed and the facing toward the other bed> I wish you all the best!

The mezzanine and storage spaces. Next to the mezzanine the builder installed a little door for us to give us access into the roof space. As the kids are using the mezzanine as a chill out area to watch TV play video games the storage now holds their board games, art and craft etc. The girls painted the walls to brighten it up. As the ducted system didn't work too well at the front of apartment we had to install a split system AC to cool down the study and the two front bedrooms.

Sorry family house needs at least one bath. We may not need ours often now kids are teenagers but my 16 yo still has them sometimes as does my 18 yo son and when you come home after a hard day riding it’s a godsend. Not to mention a future young family.

the narrowest walking space would be about 60cms (and there won't be a lot of traffic in the space and with 3800 (not 3400) the ens doorway can be pushed towards the front of the house, not centred and makes more standing room in front of the shower and easier access from the bedroom to the ens but also depends on the distance from the new wall to the side of the bay opening and that was probably centred when the house was built and before the wardrobe was installed so you need to carefully measure the room again... we now have three different widths for the room and the hall is shown as metres wide!!...is the master bedroom 3400 or 3800 or 4460 wide (ignoring the bay window) and what is the length of the whole room (ignoring the wardrobe) and what is the depth of the wardrobe from the outside and also measure from the outside of the architrave around the bedroom door to the front of the wardrobe ..could you gain some space by moving the bedroom door closer to the wardrobe and/or hinging the door to open towards the wardrobe to feel less cramped? ...we can make lots of suggestions but need to start with precise information about what you already have and based on new information and the size of an average king sized bed and the wider room my suggestion would be to place the bed in the centre of the room, lined up with the centre of the bay window and then measure how much space is available on either side for the ens and for wardrobe and bedroom door and you'll probably find that even if the bedroom door is moved there would probably be about 60-70cms between the bed and the new wall and minimal space between the bed and the door on the other side so try losing big bedside tables and use hanging lamps and mismatched side table or shelves ( a cut down stool makes a tiny side table) and keep in mind that, unless you remove the whole chimney (big job but will supply a huge number of bricks if you need some paving) the thickness of the brick walls will decide how much space is available in the chimney alcove for the vanity so measure inside the chimney not outside wall spaces but, despite limitations imo the ens is well worth the effort, cost for the improved resale value and quality of family life.. but, why not move the bed and add something to create a barrier to represent the proposed ens wall and see how it feels as something like this could work but depends on accurate measurements
