Absolutely agree with blueskies60 ! Remove the artwork/bench/plant that's on the left and replace then with either a bookshelf or a tall chest of drawers. Perhaps the plant can be repositioned into the corner on the floor where this troublesome niche is (there seems to be more than enough light there for a plant) and just place something calm and simple in the niche itself - perhaps a Japanese style scroll or pen and ink art work set off with a more rounded object sitting in the left corner of the niche; a gorgeous rock, a lovely candle, a calming statue... If you have (my preference) a chest of timber drawers on the left where the current art work is, you'll break up the symmetry, have more storage and have another surface upon which you can place a changing display of objects. This is the area that I would utilise for a mirror.

DB.....A LOT of ideas and advice flying around here.......skimming through I see you are endeavouring to establish a basic concept for a designer/architect to consolidate for you, which is great.......whilst you may think this is a logical approach to achieve the best outcome, you are arguably just throwing around random ideas rather than properly resolving/focusing on the critical aspects ........my advice is do this: firstly clearly ascertain two things on paper, not in plan or building format but in writing...that is 1. List all your requirements/needs/goals and 2. Nominate a budget. Next, identify/research a logical local designer/architect option and approach them with this information....A designer's job is to come up with an appropriate concept/solution that best balances your requirements, aligned with a budget and of course make it viable within context/site. Sure, you want a cost effective/modest result, that's fine, and that will influence the solution, but as a general comment it feels like there is massive potential being missed considering the site..it dens;t necessarily have to be that big or fancy, but you have to put the EXPERIENCE of the home front and centre of the process, and not just think of it as a kitchen or whatever laid out this way or that ....This is about an amazing site and the living experience of that and the design should be based on this and bring together your specific requirements elegantly balanced in context......The issue I have scrolling through all this is that you have all these almost disconnected ideas of building form, but you have this incredible site....... the process of resolving the spaces ideally needs to develop from cues of the immediate environment/site in order to make the most of it since you are pursuing a customised solution.....agree with MB, every project has a budget and ultimately from experience this is in general the ultimate/overriding constraint. This project could be anything upwards from $500K and it will come down to the working out how far you want to take it, and what your priorities are over various levels.......this one has seriously significant potential -make sure you make the most of it as you're truly fortunately to have this opportunity to build a home for you and your family to enjoy there.......best of luck :) PD

How's it going ? U in yet? You loving the country life? Great flower stalls on that road, or use to be! $2 bunches.. Can you look at my 'tiny house' the size of your powder room..lol https://www.houzz.com.au/discussions/6042198/those-with-an-eye-for-colour If you have any other ideas. I got some good ones already. But throw any more around that you think might work.

Extending out to the side was also our initial idea but we thought it might be more cost effective to relocate areas within the current floor plan. An architect friend of ours also thought for the space we would gain with a side extension it wouldn't be worth it. I think if we were to extend to just past the first set of french doors it would look like the photos you have shared. Love them! Now you've got me thinking of extending again, hehe. My husband really wants to unite the split stairway and I fear that will be quite costly.
