How many bedrooms? Could you sketch the layout? I think there's a point at which the size and functionality of an en suite makes it debatable whether it is an asset to the property or not. A tiny basin like in the photo and lack of wall space for towels rails is a negative for me. If the house is three bedroom you don't need two baths and you might not need two showers but a separate powder room can be useful when the bathroom is in use or for guests to use without the residents having to move their toiletries and wet towels out of the way. So I was thinking would a two way bathroom including a toilet and a separate powder room enhance the spaciousness without the downside of 'only of one bathroom'? If the house is four bedroom then I think it becomes more important for it to have both a bathroom and an en suite. I agree with georgi02 about clean lines and clever storage to make the most of the space.

I think you can definitely do this, provided you can move your door which you said you can. I have an ensuite at the side of my main bedroom - it's small but perfectly adequate. I measured it and including all external walls the ensuite takes up 1.4 x 3.05m space (my bedroom including the ensuite is 4.7m long so shorter than yours.). My room is wider (3.9m) so I can have a wardrobe along the wall where your door is and the bed on the opposite wall. But for you, I'd keep your bed where it is and look at putting your bed in a 'wardrobe wall'. you have the depth (1000mm) before the window starts and I think 3.3 m is wide enough ... ~800mm robe either side of bed. See pics below for what I mean. Only you will know if this is too squeezy but an ensuite can make so much difference to your lifestyle, I think it could be worth it!

Thanks Margot, north is to the right of the plan above, but the master and theatre (east) face natural bushland, and the master is not to the right of the design due to cars entering on each street coming towards that corner (street to front and right). Being a corner block we wanted to keep as much privacy for the master if possibly. We plan on a full fence to enclose the back bedrooms and following that a white picket fence or other permeable fence around to the front, with trees planned on the north and east sides. It can get quite hot in summer here so not hugely worried about heat and sunshine etc. Also wanted the master to face the natural bushland. The garage could go on the boundary, though adds more cost and there is a small power dome so the driveway would need to curve around that. We have taken on board feedback for the bedrooms and powder at the back. Will have a play around and see what we can shift to make the bedrooms bigger etc. Thanks so much for the help :)

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
