sorry for the delay, internet probs..The measurements look better than expected but the headroom in the stairwell is a problem ie if the new stairs begin at the old toilet door by the time you reach the back wall of the toilet going down you haven't gone down far enough to avoid hitting your head on the floor!!.. one solution is to have an upstairs laundry, or take space off the new living area and i've attached another idea but, with the accurate measurements there will be other ideas and i'll let you know..

I'd probably echo a lot of the other comments. The bathroom seems quite large and could be smaller or even split into two smaller bathrooms (ensuite and main bathroom). I'd also consider just including the laundry in the main bathroom. I don't see the need for a separate laundry sink provided you have a decent sized bathroom sink (although your needs may vary) and it would potentially be a much more efficient use of the space. The kitchen seems particularly big to me. I don't really see in the value in having such a large return with bar stools, etc. Surely in such a space, it would be easy enough to move to the dining table to eat, socialise, etc. I think it would be better to place the kitchen along the length of the wall (scrapping the "corner" bifolds, but maybe utilising a window splashback to retain natural light) to really open up the living area. I don't think a bench is necessary. If you position the dining table appropriately, it could double as workspace if necessary, but a long, linear kitchen should provide you with plenty of workspace (and, at one end, potentially room for a built-in study nook which would probably be valuable for a growing family). Ultimately, I'd do a lot of research. Houzz has a bunch of great examples about terraces, for example: [https://www.houzz.com.au/magazine/6-inner-city-terrace-renovations-that-conquer-common-problems-stsetivw-vs~52479198[(https://www.houzz.com.au/magazine/6-inner-city-terrace-renovations-that-conquer-common-problems-stsetivw-vs~52479198) [https://www.houzz.com.au/magazine/my-houzz-a-renovated-victorian-terrace-with-lofty-appeal-stsetivw-vs~69162741[(https://www.houzz.com.au/magazine/my-houzz-a-renovated-victorian-terrace-with-lofty-appeal-stsetivw-vs~69162741) [https://www.houzz.com.au/magazine/my-houzz-a-modest-terrace-impresses-with-a-bright-cheery-interior-stsetivw-vs~74631928[(https://www.houzz.com.au/magazine/my-houzz-a-modest-terrace-impresses-with-a-bright-cheery-interior-stsetivw-vs~74631928) [https://www.houzz.com.au/magazine/houzz-tour-bondi-terrace-reno-captures-light-stsetivw-vs~26541297[(https://www.houzz.com.au/magazine/houzz-tour-bondi-terrace-reno-captures-light-stsetivw-vs~26541297) [https://www.houzz.com.au/magazine/5-city-terrace-houses-that-surprise-inside-and-out-stsetivw-vs~27642618[(https://www.houzz.com.au/magazine/5-city-terrace-houses-that-surprise-inside-and-out-stsetivw-vs~27642618)

Oh Sharon! Yes, your home theatre is really too small as a home theatre. Get a big screen TV in there and you won't be able to sit far enough away in your home theatre recliners. I would suggest that you think of it as a second living area, maybe a kids playroom or games room. I would take a guess from the dotted line around the rear alfresco that your home has no eaves. Furthermore the two biggest windows in your home that have NO protection are facing due west, which gets the very worst of the hot summer afternoon sun after your house has heated up. I am afraid to say that you are building the hotbox from hell with a bright and sunny home theatre room. If you could flip the house then the smaller windows to the laundry, bathroom and bedroom 4 will get the worst of the summer afternoon sun, with your meals area and home theatre getting the morning sun. If you can't flip the house due to the crossover location then you really need to find another plan that works better for your site, or buy another block with the opposite orientation. North to the rear is the best, and north to the front (like you have) is the worst. You may want to read up about sun orientation and passive cooling. https://www.yourhome.gov.au/ Is a great resource to start with as it divides Australia up into climatic zones and describes the best way to design and build for your location.
