What a gorgeous area, I would give it a conservatory feel. Leave the tiles to define the area. I note she has a rattan tub chair ?? I would move that to that corner, find it a mate, move other cane and rattan accessories to there, add a small round table and some lush plants. The tub chair looks like it would double as a lounge chair as well as a dining chair for breakfast or casual lunches. Sorry I can't find photos, everything is for much larger areas.

I think the first layout is fine. You might want to consider moving the door for the storage room of the master bedroom so that it opens into the hall. That way the kids can use it for overflow storage. Also, that hallway is big enough that I think it could hold a large armour, providing more closet space. (There's no need to sleep in the same room as your clothes, so long as they're not too far off.) Also, don't forget that while the drawing shows kids in double beds, this need not be the case, so there will be more room for furniture (dressers or whatever) in their rooms. Finally, that step to bedroom 4 will not be odd at all. I've seen it in other homes. It looks clumsy in the drawing but it isn't. What you'll see when you come up the stairs is a bedroom door on a slight diagonal. It's only an odd jagged step if you walk like a robot, in straight lines along the wall, which is what your eye is doing on the drawing but you won't do in real life.

Could you put the laundry behind doors so that you won't see it with the walk through...by the way...I am just over the water in OZ, know what you mean by costs... will get some pics....this would be my option...just going on what you are saying.... The good thing about this is that you can shut the laundry away except for when you are washing...... I would have the washer with the dryer next to it if you can and put a bench over the top of the both of them....for this it is worth getting a front loader if you haven't already got one.. this will avoid the bench on the other side...it can all be contained and done on the one side of the laundry. Don't go for sliding doors ...the glass look great but they will need a bottom track and if they don't have one...they will move a lot....not great for this even though they look great. As for having the bench over the top of the washer and dryer, you can then have overhead shelving, does not need to be cupboards as the bifolds will hide what is in there...double cost other wise. hope this helps...Robyn

You could do a wet room on the south end of the room with the tub and shower combined to conserve space. Window would go above tub, however with privacy in mind it would not be low as you have in your cad drawing. see photo. Vanities would go on the west wall with toilet on the east wall. I am guessing at the dimensions because you mention meters and in the US we use feet, but it sounds like about 9'x15" ? The location of the entry door really impacts the layout of the room, but it looks like it cannot be moved.
