Cool! Looks interesting.

your dilemma is difficult to understand without more information and would be so much easier if we had the original whole house plan with dimensions and showing front and back entry, and views, size and position of prop0sed pool and all existing windows and doors, any walls doors or windows that can't be changed and direction of north...as well as any special requests for the kitchen

Finally the job of replacing the spa bath with a normal bath has started. Firstly, part of kitchen ceiling removed to undo spa waste, then row of tiles removed to jiggle out the spa - no good! Plumber had to cut spa shell in 2 with grinder to remove. New replacement bath, same make and model, now installed, waterproofing done, tiler called in to assess the retiling job. I thought I'd be clever and order some white replacement tiles to help - ha, tiler says they are a slightly different colour but have just enough of originals to finish the job. Heading in the right direction!!

I do like the design but wonder how easy or difficult the postie would find accessing it, but that is not a design issue. Agree with bigreader' observations. It goes well with the house.
