We're building 4x3.5 Two with ensuite and the others with a jack and Jill. Life has changed unfortunately and now everyone in the household works, kids stay at home longer and ageing parents sometimes move in for care. At the moment we have a 3 x 1 and really the only thing we really want for is a second toilet, which growing up we had because we had the one out the back with the red backs.

Hi Paul In apartments, the killer for layout changes are always drains, then water supply, then load bearing walls. Before you consider doing any changes to the layout, I would advise you to locate the drains (pics would be good) as they will likely restrict you. The drains are important for obvious reasons but also important is the fall (ie downward slope) of any drain you wish to install in a separate location. It means you have to take into account more height the further away from the existing drain you go. It is likely that your existing laundry trough/basin has a drain going down to the floor, and this is going to interfere with the proposed ensuite entry location. Ditto if it is going into the wall. The big one is the new shower. It will need to have a 50mm waste (drain) in the centre of where your washing machine now is.... and the question is where is it going to go.... I would suggest swapping the vanity and shower over to access the existing trough waste if it is large enough. In a lot of these older apartment buildings, the waste sizes are down at 38mm, which is not going to drain fast enough for a shower. If your existing waste is that size, you will need to have a hob to the shower as it will fill up, and you will also need to check health regs to see if it is allowed in your state. To get the drain for the new ensuite vanity and new laundrette sorted, I would punch through the new kitchen wall and run drainage along the wall behind the new cupboards and around to the existing kitchen sink waste. This will give you plenty of fall and a place to hide the pipes. For the new basin to the existing, you will need to see if you can get it around to the existing basin waste in the bathroom adjacent by running it around and under the bath. Cheers

If you can swap the toilet to the outside wall in en-suite that may allow a slightly bigger vanity. With bed 3 if that will be a study you could take space for master wardrobe. I note you really do need the extra master robe. If you are happy with only one bedroom on that level, maybe change the bathroom up their to a powder room and enlarge the en-suite.

I know it would get more complicated and probably be more expensive , but basically you are trying to get too much in there IMO . Everything is a compromise , and in fact , even if you had say a garage with power and water on , and moved the laundry there , you are losing both an inside laundry and a bath , to get the luxury of an en-suite . Lose 2 things to gain 1 in my opinion , so unless your main focus is an ensuite at all costs , it doesn't make a lot of sense . Me , I'd either live with it as it is , or depending on rules , regulations , present construction ( brick , weatherboard , etc ) , boundaries , even whether raised or ground-level -- I'd look at adding on , even if its a step up from a lean to -- I know its a 90's sort of thing , but an ensuite attached from either Bed 1 or 2 would possibly make at least as much sense .
