nomadicmel - I would not consider removing the window at all - ventilation is so important, or you will give yourself even more problems, especially if you are having a dryer in there. Have you given consideration to where that will be vented anyway. If you are planning ahead for teenagers (and good luck with that) having a bath in one room and a shower in the other will be a very good investment, teenagers are anal about their privacy, but do be very mindful of storage - a vanity in the laundry will really be important - just somewhere to put a hair dryer for example.

the whole house needs attention, Me and my youngest daughter with her Three Boys, live together in a Three bedroom one lounge and one toilet / bathroom, yes we are renting, through housing department, yes the rent is convenient as we pay a minimum of a quarter of our income, just need a better laid out house design with the toilet being a separate room with an extra toilet thrown in, in the laundry area, yes we are blessed to have a roof over our heads, we live in NSW, Australia.

Hi AndrewJason, I love cavity sliders. they are there when you want them but not visible when you need the space open. Having said that they cost more, take a bit of wreckage to set up and in you WA case you will be wrecking brick walls to put them in which might be a stretch of mess too far. BUT you will need to weigh up if they are worth it in the end. I do not think the build will be too bulky in the kitchen/dining because it will be superbly practical on both sides and it maybe just a matter of what you are used to. Not sure about "Average Joe...…" we are all good at somethings, mine is plans, function, practicality, solar. Yours might be brain surgery, empathy for unwell folks, kinda or you make the best seafood lasagne in the world... we are all needed to make for a great world: and it really is that!!! Good luck with your splendid home: I think it is beautiful. And PS if you do make the best seafood anything I better have your address....!!!!!!! MK

search bathroom dilemmas on HOUZZ and you will find hundreds of examples of bathroom plans and some elevations but you should also research standard sizes for all bathroom fixtures to help understand spaces needed so you can produce your own plans, cross sections and elevations...built in baths are simple but free standing baths needs extra space for cleaning and, although there are numerous different sized toilets a good size floor area to allow for a toilet is 80cm x 80cm to allow for knee and shoulder space regardless of the size of the actual toilet and then there's a whole range of other dimensions needed for disabled bathrooms and different sizes for a walk in shower and how to avoid overspray so there's is a lot to learn if you plan to design bathrooms
