prefer the last option with a separate ens and access to wiw..the rooms are so generous there's space for a freestanding bath 1800 x 800, a giant shower 2m x 1m with steam and double taps and shower roses, twin 1200 x 500 vanities with plenty of storage (consider wall hung for an even more open feeling) space for 80cm wide mirrored wall cabinet (or bigger subject to height of windows) and a full sized enclosed toilet space and consider 1800 -2100 tall glass sliding screens for shower and toilet spaces (with frosted, clear or decorated glass?) and there's still space for a chair and heated towel rails..should be better than any lux motel room

I think siriuskey's latest plan is better, as it extends length of double shower which resolves the issue of chute/cupboard combo door, and allows for a wider door into master bedroom. A wider door will be a more dramatic entrance to this large suite, so worth seriously considering. The plan does eliminate the linen cupboard; however. Personally, I would not want to store my bed linens in a bathroom simply because of moisture/steam. The generously sized walk-in robe has more than enough space for bed linens to be stored. That's where I stored mine in our last home. It was very convenient and only a few steps from shelf to bed. I stored all other linens in the wardrobe of upstairs spare bedroom, close to the kids' rooms. Re the double shower - I mentioned previously a 1.8m length is sufficient IF you have a glass sliding door that slides alongside track like a barn-style door. Hubby & I did regret not thinking about how awkward a hinged/pivot door would be. Current dbl shower is 2.2m and has the sliding door I described. We didn't request a longer shower, but the architect drew it up that way. Given my choice, I'd always go with bigger.

The doors can be hinged to open outwards. Ours opened onto verandah and back garden. Had drapes shut for sleeptime. It was a narrower sitting area so we each had chair and ottoman on either side of doors. Wasn't wide enough to accomodate side tables, which we would have liked for setting down books and coffee cups. I used the window sills next to chair for this. The devil is in the detail, and can learn so much through trial and error.

it should be easy enough to use bed 2 as space for an ensuite but that means losing a bedroom...do you have any other long term plans to add extra bedrooms, new kitchen etc eg the old extension seems like a much better location for the kitchen, make a bigger dining area and maybe add a screened room across the back to take advantage of your good climate but neither idea solves the problem of the missing bedroom, could the living area be converted to extra bedrooms but how you would access the clothesline from a laundry in the garage...is there space to add an external door on either side of downstairs? maybe the cellar would be a better location for the new laundry with closer access to the stairs and an existing external (front) door and add laundry shute from the upstairs bathroom but making scaled plans is difficult as the real estate plans are inconsistent ...please confirm the dimensions of all the rooms (including bath, toilet, biws and hallways and i can make a better scaled plan to share
