Simon, 100% agree with OKlouise, she's on the right track..... I've done a stack of these types of things.....big projects, that call for professional solutions....what I would say as a start is that there are always various ways of achieving your needs. It's not just about the rooms, it about the quality of the spaces, the proportioning their connection/relationship to both the adjacent internal and external areas.....I'm guessing from the floor plan you have a lovely older home with some traditional character...depending upon your needs for the rear yard (pool??) I see opportunities here for alternative configurations that would open this thing up and let more natural/north light into the main living/kitchen areas.....if you want my 2 cents I think for a home of this scale no you shouldn't have to pop through the kitchen to get to the study...a study nook within a kitchen is OK but as a differentiated room that could potentially be used for other purpose (always good for the property value factor ;) )....its ALL in the planning, there's a lot of money involved here so make sure you get it right and if it doesn't "feel" right, then there's an issue.....clearly here you have priorities and vision for your study, and that's great, so make sure you get it right and that the outlook is how you want it to be - so it should, it's yours!.....but it's not a simple as just swapping the spaces around/over...floor plans are delicately balanced and carefully considered/arranged and when resolved properly/professionally they will just sit there and be unquestionably "right", appropriately scaled & proportioned, not awkward, representative of your specific requirements/priorities and balanced within the particular context....

Jodie, measure 212cm from your floor and mark with a sticky note or piece of tape. Measure from the mark down 70cm - this represents bottom edge of mirror. Will this be adequate for you and other adult/s using it?

Hi Dean I think there is a lot going on with the items pictured. I agree with Dr Retro (as just about always!), there should be one "hero piece" in the bathroom, and this should be the beautiful freestanding bath. That egg shaped toilet reminds of something from Alien!! It doesnt really go with anything else you have selected. There are plenty of rounded back to wall/hidden cistern toilets out there (dont buy a cheap cistern!!) that dont look like they are trying to steal the show. Also, why the sharp edges on the shower ware and basin? They kind of jar against the fluid lines of the bath. Methven AIO Aurajet is an amazing looking showerhead (i specified it for a client recently and they love it), and would go with the fluid forms look. I would also be tempted to get a basin that is formed in the vanity, so you dont get too many cut out shapes against the dark tiles. Food for thought ;)

Sorry for the delay in advising you of where to purchase the fittings. I tend to purchase fittings for clients within a project. But, The top one can be purchased from Beacon Lighting and is on special for $96.75 each. The middle fitting is from Emac & Lawton and the last one must have vanished from production, as I haven't been able to find it again. I have included a fitting from Mondo Luce below, called Dora Emac & Lawton have a new fitting as well - Amstel:
