you said you could extend towards the west to replace the laundry but what's the distance from the side of the original dining room to the western boundary and what are your long term plans for the old dining room, kitchen and the space behind the garage? if you expect to extend, as me me already said, it's much better to plan the whole house renovation and it can also be more cost effective to add new rooms than to rearrange existing spaces even if you have to do the work in stages but, as we can't read the writing on your plans, it difficult to make specific suggestions and i don't understand where you plan to add the new kitchen ...does the house have only original rooms or is part of the house an old extension? what are all the floors and walls made out and what is the height of the back deck off the ground? please show room names and dimensions on the plans in larger print and some photos inside and out would help understand the existing spaces but my initial thought would be to have a new kitchen,pantry and laundry on the garage side and use the old dining room kitchen and laundry bathroom as a new master suite..but depends on correct dimensions.

There is no easy answer to this as it depends on your budget, the condition of the existing slab under the carpet, and the order that you are going to approach your renovations. Have a look at one of my Secret Design Studio's Pinterest boards for inspiration such as this one:https://www.pinterest.com.au/secretdesign/aussie-mcm-interiors/ Parquetry is appropriate for the age of the house, and can be staged according to your budget and renovations, and is easy to work around existing cabinetwork. You need to carefully consider which comes first the kitchen, or the kitchen floor if you are planning to renovate the kitchen, but parquetry does give you better flexibility than a tiled finish. There are so many other options available that may suit your home so do your research, or engage a professional who specializes in mid-century homes, and don't go with anything that will date it as an early 21st century material or renovation (like polished concrete). None of my clients want to live in a museum, everybody wants 21st century conveniences, but still respect the heritage of the home. Celebrate what you are lucky enough to own, rather than modernise to be like every other current renovation. Feel free to check out my Houzz reviews. Best of luck, Dr Retro of Dr Retro House Calls

Audrey In Brisbane we can legally create a house with semi-self-contained units/flattettes. This can be done without a Develpment Approval. It does need a Building Approval, but for the changes you might need, you woudl need a Buidlign Approval anyway. These houses in Brisbane can consist of up to five bedrooms (assuming 1 person per bedroom) which can be ensuited and have a tea bench (small hotel like kitchen). You then provide a share kitchen and laundry. Ideally, you could also incorporate a common room. This house appears to have good bones to achieve this. With Airbnb I am currently doing similar to what you are looking at (although in Spring Hill). They take only 3%. My house needs renovation, but in there $180/week gives them a room and share bathrooms and kitchens and all bills paid. This property you are looking at has this opportunity immediately. With not much work you could provide a mix of products with several ensuited rooms as well as just rooms. If it was me, I'd be claiming the rear as mine and renting the house's front bits. I think you could bring up to $600/week depending on the condition of the property and location (again assuming you kept the two rear rooms and rumpus as your retreat with garden facing rooms (so you can keep an eye on the dogs, tend a garden and have an escape from the rest of the house. This is not to say you have to totally exclude tenants from access to it. If you want to chat more please feel free to contact me. The house appears to have great potential.

To my untrained eye, it strikes me as a really nice design generally - so great job. I’m keen to vote, but feel like we need to see the upstairs layout for Option 2 to understand the trade-offs (what will the space previously dedicated to the laundry be repurposed for) - sorry if you’ve posted / explained this and I can’t see it working off the phone.
