Hi, I know this is a long time after your first notes but I can't help but comment. I love the idea of the shallow wall that goes to the ceiling with a ladder. We lived in a home where the refrigerator was outside on the porch due to lack of space. With very few cupboards, I did a couple shelving units built between studs like that. I measured the height of each shelf away from the one above it with my canned foods. Turned out great and it is amazing how much those 2 little shelves could hold. I also want to say that I don't know building codes in your country but I agree that you should get at least 3 other quotes. With a concrete wall you can put electrical in that area. You can just have them use metal, electrical conduit. It does show (toe kick works, too!) but it is very non-invasive and should be cheaper. I really love the kitchen that Edith Martins posted. It is such a little gem. I can just picture myself working in that lovely place. Go slowly with your renovations. Listen to all thoughts and suggestions. In the end, this is your money you are spending and your home, so be sure to do what makes you happy. Lastly, there is NO box that you have to work within. Look online, watch Tiny House shows, go to architectural websites for ideas. Do YOUR thing. And, please post pictures when you are done! Best.

Could you swap the fridge with the wall oven, going by your photo both fridge and Wall Oven would fit side by side. I would definately have the fridge on the cook top wall and not on the other side of the kitchen. I see by the photo that the timber beam could be in the way, I would speak to your plumber who should have a simple solution on ducting the range hood. A simple one built into a special cabinet above the cooktop can recirculate or be ducted outside by either exposed stainless tube for your industrial/country look or have the ducting boxed in, the ducting can be flexable so no problem avoiding beams.

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....

Thank you siriuskey :) The location is metro Adelaide so very hot summers and cool winters. Plans are for timber frame wall and roof construction, rendered hebel panels for all external walls and colourbond custom orb roofing. Party wall construction with 25mm gyprock shaft liner panels. Laminate timber flooring for living areas, carpet to bedrooms, tiles to wet areas, stone bench tops. Exposed aggregate concrete driveway & front footpath, grey concrete/paving to side path & pergola area. The market for these homes is predominantly downsizers, first home buyers and possibly single/separated parents with young children who do not want a large block of land. Basically nicely completed traditional/modern homes with above average finishes but not too high end.
