Nice ideas bellesum. Here is the same thing with l-shaped kitchen. Bathroom ends up being a few inches wider to get the w/d to fit...you'll need to look at this in more detail because the w/d often requires extra space behind for connections. As drawn it's exactly 760mm square. If you do need more space for connections you'd have to fiddle with the design of the cabinet. Perhaps the refrigerator, pantry and laundry centre are one large (and fairly complicated) cabinet. That would save you a few mm of wall space. You could even put a "hidden" sliding door on the tv wall that opens to reveal the w/d hidden inside.

answering your questions: change the sliding door to a bench height sliding window and use the salvaged sliding door in the western end of the dining room where the best entry position is for the deck, you MUST have a proper legal drains do not consider anything else...the drain pipe for the garage laundry can be on top of the concrete floor, behind the washing machine and through the sink cabinet and/or under built in storage and only needs a few cms not a whole floor and no stepped up area that you would see or trip over.. the laundry can't be in a separate room as there's not enough space for a separate laundry without compromising the size of the garage...a laundry cupboard 80 cm deep is enough for the washing machine (allowing for the drainage pipe) you could use the old line cupboard to store anything you want but it's not cost effective to change, the entry foyer is already as big as in many modern homes and there's generous flatpac biw space in the small study.... the family bathroom is 2380 x 2370 (ie the old study minus 1m for hall way and wall thickness and, arranged exactly as shown to allow for the wide window there should be space for a bath up to 1800 x 750, vanity about 1200 x 500 and shower space 1200 x 800 and leftover space makes the small linen cupboard with the door deliberately opening towards the shower to use the back of the door for hanging racks for towels and clothes....btw i understood your priority was maximizing separate sleeping rooms and minimising costs...my last plan has five separate sleeping rooms plus the lounge with sofa bed totalling sleeping places for at least 10 people plus the potential for bunks in the garage so you need to decide what is most important and where you're prepared to compromise

Hi pallavi the cut out area would be great for the marble table. A large round mirror above it (i just bought one from freedom at a reasonable price). Maybe a hanging macrame pot plant in the corner (hanging from thr ceiling) where ur current plant is......this would be a vocal point as soon as people walk in. Yes a piece of artwork on the opposite wall would be nice to balance both sides. Hope this helps you alittle to get ur creative hat on and just go for it. the only problem is there is no storage as u wanted but you can always put a nice bowl on the console for u to store keys.

the wall between the ens and wiw is only 2.2m and not possible to rearrange the doors without losing the bath and the bed on the other wall gives more direct access between ens and wiw but if you can live without bedside table a queen bed will fit between the doors in order to create the bigger pantry and linen and keep a separate toilet next to the bathroom space had to be taken off the laundry...making the laundry bigger again will need space to come off somewhere else the measurements for bathtub, shower, vanity and toilet is the space allowed and no bigger.... another thought to consider would be have lockable doors to close off the hall to the laundry and you could have a kitchnette and entry in the laundry space and use the lounge and beds 2 and 3 as a self contained rental and keep paying guests out of your part of the house including the entry living, master suite and MPR and share the laundry...extra privacy and security that your dad should approve
