I’m assuming you don’t have an upstairs neighbour. Do you have a body corporate? Are you on a concrete slab ie not impossible but costly to move plumbing.

is there any legal or convenience reason why you need to keep the hallway from the garage to the rear garden and do you need two separate full bathrooms?

Hi, no it is a single story unit sharing a wall a neighbour on the living room/bedroom wall. on stumps so access wouldnt be a issue.

more just like the idea of a ensuite/wir if possible.

prefer to avoid anything majorly structual such as removing brick walls,

its a 1970s brick veneer single story unit

Without a properly dimensioned plan it is impossible to provide much advice. But considering a hall way width at best you would get some narrow shelves along one side, so not much of a walk in robe. I wouldn’t put a wall up as you can’t afford the loss of space for wall.
Getting a toilet in bathroom would need to find 800 mm between wall and shower screen. Or perhaps move b
Vanity to that space and put toilet where vanity is.
Your laundry now is basically a cupboard on the hall to the backyard. So unless you want to turn the other bedroom into a living space there is not much to be gained from moving it elsewhere

This may give some more room for en-suite, by converting laundry space to robe in master, leaving the exit hall, move laundry to meals area and out table in living area.

Why don’t you convert the laundry to the new ensuite...plumbing is already there. And knock through the kitchen/garage wall to make a doorway to backyard access.

Without dimensions of the passage, I would consider using it for the ensuite, easy to fit another WC, basin recessed into the wall, shower with glass door opening out to the courtyard., Open up a doorway between garage and kitchen, add a bank of cupboards backing onto the bathroom, open up wall between kitchen and living making that a sit up to bench. Access to courtyard is now via the laundry which if enough room could be made into a European style laundry behind doors.

Just a rough draft sketch to generate some discussion and prompt some question's .

1. why does the garage need to connect to the small courtyard? That passage can enlarge the bedroom
2. same question re the laundry.. and it can be included in bathroom (4), you could just access the courtyard thru bedroom sliders
3. open up kitchen to living / dining space
4. bathroom with laundry facilities
5. en suite with long wardrobe either side, note bedroom is a bit narrow so another option is needed...

Finally your dimensions are a little vague and walls are never pencil thin so not much point developing it further until you are more precise...

@oklouise Thankyou so much!

i really like the design, definetely agree after you put it like that. seperate powder room with a basin would work well

thanks heaps

If your property has a Body Corporate you should talk with them regarding what changes require their approval before going ahead.

Jordan. Many of these ideas, while interesting, require extensive moving of walls and plumbing issues to get the new WC in place. Your bathroom is big enough for shower, vanity and WC with the above arrangement. The entry door needs to move aroudn the corner opposite Bed 1 door. Build longer robe into Bed 1 on SW wall to allow widening of WC to add vanity niche without losing furnishable space in Bed 1

Moving the laundry into the kitchen area will allow better usage with a plumbing duct shared with the bathroom fixtures. This move will free up space for more width in Bed 2 for a Queen bed and circulation.

Moving the wall to the living room to the SE into Bed 2 will give you more furnishing room in the living/dining area. I also suggest a change can be made to the kitchen, opening it to the living room and getting direct access from the garage. The connection to your courtyard for plants, etc is good to retain.

Adding my thoughts, you mention that your unit is on piers so I would maintain current bathroom and separate powder room. Adding an ensuite to the current passageway which could have a glass door opening to the courtyard. Putting the laundry behind doors removing the door into that and adding another exterior glass door so that you have a visual on entering the unit through to the courtyard and light,. Opening up a doorway from the garage (as per my earlier sketch) into the kitchen. By having a 2 bedroom 2 bathroom unit it would be very appealing to singles wanting to rent.
