hi we have about six months ago now, re done our bath room , similar size to yours, and , i can take some photos and email them to you , we have maximised space, and walls , put in a white stone bath under the window , it is a metre in width , with a cool water spout coming off the centre under the window we pu t afalse ledge in to sit , candles etc on , , we tiles floor to ceiling, off white , wall mirror cabnit with three mirrors , inset into the wall so its only sits out a we bit from the wall tiles , floating bath room vanity , so that it makes the floor space look bigger , . matching stone square basin sits ontop of the vanity to one side so plenty of room to sit all your bath room stuff when need be , seperate shower all tiled as well , with inset , shelves for shampoo etc, also , when you open the bath room door and walk in when you close the bath room door behind it next to the shower is a very narrow floor to ceiling shelvec for towels, now the hole is there we jaust havent got the shelves put in yet. , we gt loads of comments as the bth room dosent look small evn though it is , , most expensive item the sqwat extra wide stone bath , made to order basin / tap ware and shower spray thing ,oh and the white stone vanity which we had made to order as well , due to the sizing .

Thanks oklouise. I love your ideas and the ensuite layout is great. However, I don't think I made my dimensions clear enough and I don't think the rest of your design can work Bed 1 - 3600 X 3600 Bed 2 - 3700 X 3000 Current bathroom - 1960 X 2600 Current laundry - 1820 X 2600 Current toilet - 1340 X 1100 So if we keep the current bed 1 and bathroom space and convert that bathroom to the ensuite, that leaves approx 3200 X 2600 for the bathroom/toilet/laundry. Ideally we would leave the current windows ( a 1000x1100mm sash window 1200mm from the floor in the laundry area) and a high (550x700mm window in the toilet area) which makes juggling the space a bit challenging. Thanks so much for your help with this!

something like this may suit without altering the plumbing too muchor this arrangement adds more privacy from the living area, has the bath in the main bathroom, a bigger shower in the ensuite and more space for mirrored wall cabinets and a fixed "window" above the mirrors could add extra daylight between the bathrooms

No-one seems to have brought up what , to me , seems like the second most logical suggestion ( admitttedly , without knowing the planning rules ) . The logical still seems to be to sell . Failing that , I'd look at extending the study , taking in the courtyard , alter the internal door ( suggestion - a single door on the 'right' side of the existing study doors area ) , add an ensuite ( relatively easy as the existing bathroom is just through the wall ) , and make that room your master bedroom with en-suite . Move the ranchslider , or add a roof to floor window , to get natural light into the new master , and possibly add a skylight or two above the dining room , as it will lose the ranchslider . Not perfect , but if you go up it will be costly , there are engineering issues , matching materials , new roof , all sorts of logistical problems . 'My' suggestion cuts down outdoor space , and may exceed the building to land-size ratios , but its so much easier building , engineering , roofing , plumbing and materials matching wise , gives you all or most of the space you are after , so IMO way more bang per buck . Having said that , only you know your priorities , budget and what you are happy to give up to gain .
