Well here we are yet again! I've not changed my opinion. The toilet-loo-privy- whatever one wants to call it needs a room of its own. Makes no sense to me having a "privacy wall" behind which to hide the pedestall if it is placed in a shower or full bathroom...the locked bathroom door is all that's needed. Seems to me that the concept of a separate toilet room or "Powder Room" (Why that title is anyone's guess)...was a sensible and accepted concept of homes in the 50's. It wasn't in need of any "polite" title, it was simply referred to as "The Toilet"..meaning basically -".where to freshen up". My idea of a perfectly sensible toilet is a separate little room housing the pedestal (toilet bowl) and a little basin with running water. Optional- a paper hand towel dispenser or one of those blowers...or a small towel rack and/or a nook for toilet paper...mabye to accomodate wet wipes in the absence of a basin or even where there's a basin....a nice comfy little Toilet Room..

if you decide to have a wall hung toilet or towel rails on the toilet wall the cavity slider wall will need to be reinforced to support the weight and a wall hung toiler with inwall cistern will mean that the cavity slider would have to slide towards the vanity..Either hinged or cavity slider doors will be good in this situation although the hinged door has the useful option for hooks for clothes or an extra towel rail...btw consider moving the master bedroom entry door for a more generous entry into the bedroom

Thanks once again oklouise for your comments. I have already been told by the draughtsman that I cannot put in skylights. No idea if this is true but he seemed quite sure and it was he who 'designed' the layout of said ensuite with what I consider a too small window because of ease of plumbing and drainage. He says that can be changed...............Supposedly only put like that to get the oversize plan in fir consent. This department is only interested in the outside view and the effect on the neighbours, which I actually dont have any. The positioning of the ensuite and WiR has changed too from the first plan as I had to come 'out' of my bedroom into a corridor past the WiR door and then into the ensuite. Technically they were both in my bedroom as had not entered the hallway but did not seem like it. So the wall you have now suggested for the door is a small lobby to the bedroom and I had planned to put furniture on it and a full length mirror. I will now look again at the whole space with three zones to see what can be done. I used the word solar tube as I thought that was the generic name for the 'tube' installed which reflected light into a room. Do they cause draughts? Have had no experience of them but will probably want to install one in my scullery (or Butler's kitchen) but am going to work in it a few months before deciding that. I am really quite a novice about function of installations and of building code.

more challenges!! if there's only 1600mm available in the new laundry the wall sections can be about 700-800mm wide to allow for suitable door openings but this depends on the way the doors are installed as a cavity slider needs the whole wall section to be rebuilt and a standard 820 wide external door should be able to open towards the inside as this makes the door more weatherproof and safer when there are steps outside...and with a 520mm drop to ground level (plus the depth of any new flooring in the new laundry i suggest that there should be a step down to a 1m wide landing plus a single step on either side and with careful planning the new steps could have a finished riser height (including any tiles) of about 175mm without spoiling the existing slate? BUT what is the distance from the outside wall to the railing at the edge of the verandah and what's on the other side of the railing as this may need some extra care and on site inspection by the trades people will provide more precise dimensions for all the new work
