based on available dimensions i suggest that side by side semi recessed basins in twin shallow vanities will be more comfortable than squeezing through the tiny space leftover with vanities on opposite walls, my curve may not be precise but i suggest that a 1200 x 900 fibreglass shower stall with sliding glass doors would solve the problem of waterproofing and allow for a shower door that would not need to crash into the vanities and the small section of glass bricks visible would not be affected by direct water spray,,, the wall next to the window should be sufficient for a mirror doored wall cabinet and the wall around the bath and next to the door will allow space for towel rails and the laundry basket and installing the (standard 820 wide) cavity sliding door to open towards the bath will be less work as it will use the existing doorway ...if you decide to use the void behind part of the glass brick wall painting the glass white? from the bathroom side could make the view from the stairs more attractive

Hi Siruskey (just found the thank you button) Nothing is in place - it is conversion of a small bedroom. The WC was placed where it is - and was partitioned off as you have drawn, in an earlier version... decided against it on natural light grounds. i like it tucked behind the door - the bathroom will be first room coming down the hallway from the front door. The link is exactly the type of bath I am thinking of I think i would try for something like 1500 x 750 size In the house design, there is a completely separate, attached to the house, outside loo / powder room, to be the go to loo for the garage band members /outdoor gatherings / during days working out in the garden and anyone seeking maximum privacy ! Keeping the shower behind the vanity - all tiles - no glass is appealing (not a fan of squeegeeing) 1200 seems deep enough? As long as 750 gap beween bath and shower is enough to move through easily enough. The bedroom in the old house has been lived in for 20 years and the bed has always been in the wrong place. The bulk head shown above where the two new small windows are, is where the old built in wardrobe will be removed. I have never been able to put the bed on this 4th wall - have tried it on all of the 3 other walls and it was always "wrong" - not sure if it was feng shui or not. The bulkhead is to manage the symmetry of the ceiling that has a deco ceiling rectangular panel. Partly my motive to take space from the bathroom for the BIR is to preserve the symmetry. I am trying out the 4th wall as location for bed, as the wardrobe is now storage with temporary curtains other than doors. It has the "right" feel about it. The ceiling panel is longer parallel to the window - so for a BIR taking off the "length" of the room feels better, than from the width, even though measurements are similar. What amazes me is how everything in design & planning process is connected to everything else... Fresh eyes from you (and oklouise) has been invaluable to sort out my head. .. and I appreciated your understanding of the J&J principle for the upstairs bathroom.. I think I will stick with it :)

Regarding ensuite, great idea to put a nib wall, or i could even put a 1.1m wall there and avoid the shower glass all together. Or may be put a nib wall between vanity and toilet?

I asked what he would do, if he moved in himself. He said he'd move the steel beams, but that it would involve engineering and putting the house back up on stilts. He said he'd do car port out front and build under existing rooms (excluding kitchen). He also said the engineering and putting house back on supports would be an expensive undertaking, which I dont see the point in doing, as one of the reasons I bought the house was that it was already raised to legal height for building in under neath. SO I am hoping to work around the steel posts, there are only three on the inside. I expect to build under the existing upstairs rooms (excluding the kitchen). And i'm wondering if I can have the plan, get devt approval, and do part of the work before we move in in about 18 months. Im a single parent with full time custody, so i started thinking while the kids are small, maybe underneath could just house a nanny/au pair and I could have some live in help. And then when i dont need a nanny, the part that they inhabited could go back to being for my original intention, a teenage/young adult hang out zone. I wondered about bed 4 (of your plan) being the living area and bed 5 (of your plan) being the bedroom for the live in /nanny and then the laundry temporarily doubling as a kitchenette. (happy now Ive resolved to keep the landry upstairs for now :) ) Thanks for the tip re the car port needing approval - such a steep learning curve with so many things to consider :)
