You should tell people where you want to build, your budget and the type or style of house you want? Your profile is incomplete and your ideas book empty, which will make it very difficult for anyone to relate to your project.

Great job guys, love the open plan. Kitchen area looks huge. The new blends well with the old. Not an easy task but you delivered !!

i've attached my suggestion which doesn't knock down any walls or change the entry and only includes an 1800 wide sliding door on the side of the sunroom (with or without matching windows (cheaper than doors) across the front, big stackers are more expensive to buy and install, very expensive to add security doors or flyscreens and take up more floor space with bigger tracks) and i hope the sliding door on the side would be less obvious and more acceptable to the body corporate. i suggest you keep the living room as is, change the old kitchen to a bedroom and install a new kitchen/diner/laundry in the old bedroom without knocking down the wall into the sunroom although you may wish to remove the double doors if they take up too much space..if you keep the separate sunroom it can be called a third bedroom, if you ever decide to sell...the new plumbing is on the external wall, close to the existing plumbing and it could be convenient to keep a small sink in the new bedroom to use the old plumbing...should be relatively economical and achieve your main goal, hope you like!!

Thanks again dreamer. Big reader: thank you, pragmatic advice. Certainly in need of maintenance and we will likely sell the house in next 2 years. I got surfmist, shale grey and dune samples pots to try. Surfmist and Dune were too contrasting considering the surrounding trees. Actually shale grey looked quite good, but again, a lot more brighter. So likely we will stick with Hildegard
