Well, it has been a long (and sometimes painful) process but we are nearly at the end of the extension/renovation. We ended up going with a building designer (Dalecki Design) who made a few changes we really hadn't considered (including moving the existing bathroom) which may have cost slightly more but completely changed and improved the master bedroom space. Without the pool it will be close to the upper end of our original budget but still within what we were hoping for so fairly happy with that. Overall the new living area is amazing and filled with light compared to the old design. Will throw in some photo updates once we have finally converted the front yard from a sand pit and finished off the driveway, garage door and fencing.

Hi oklouise, thank you again so much for your suggestions to help me reflect on my choices! The great thing about this whole process is that it has really helped me clarify my must haves/dealbreakers and nice to haves. Key elements that I don't want to forego are: 1) a "master suite" with large WIR + private ensuite+ direct private garden access/views. The current northern bedrooms are elevated and do not allow these elements and better suited to small kids as no external doors and can be eyeballed from the kitchen. 2)The kitchen must be the heart of the home and connected to all living spaces so the host never feels disconnected from guests & can watch kids from almost any living space.I attended a party last weekend which had the kitchen blocking the living room from the outdoor space and the host commented they regretted it after renovating. 3)The dining room must be an end destination vs a corridor so it does not become a dumping grounds for bags, mail & everything else as the nearest flat surface to the entry point. 4) All new bedrooms must also be min 3 -3.2M wide on the narrowest side for me to justify them. 5) I reviewed all my lookbooks and tear sheets pulled to date and its a clear pattern that I want my 'adult' living and dining/entertaining spaces connected to the rear garden preferably wrapping l-shape round a deck or courtyard garden. In a sense 'broken' vs open plan but still visible through glass etc. 6) I would not be prepared sacrifice the prime N/NE aspect with utility rooms. 7) I don't wish to place a verandah at the front as it will never be used except extra maintenance and can create shading in summer via other methods. 8) capacity to rent out room with private living quarters. There are many splitter blocks in my area and I don't need it to operate as legal dual occupancy. 9) single level living -no second story bedrooms etc. 10) separation of main bedrooms when renting out section of house Phew....I think thats most of the checklist criteria I have been working to. Still think tanking the street appeal/front facade style but its probably leaning toward lux byron bay beach cottage meets modern coastal with some retro elements to hint at the history of this 1950s house!

You are most welcome, I have always said that I haven't been put on this earth to "Hug" toilets, so I'am wondering who is going to clean all of these Bathrooms. Our two kids a boy and a girl had the upstairs "apartment" which they and all their friends loved. I have added a timber stair case for fun, there's plenty of space but you will need to decide what you want to do in the attic and place the stairs to open up into a tall space. I have also turned one of the ensuites into a powder room. Your Jacaranda's only drop once a year!, you used to be able to trim them by 25% each year, you would need to check with your council, we were on the lower North Shore, I think you should consider the patio side of the house and make better use of that, is the front deck something you plan on adding because of aspect, and plant some tall growing hedge ready for the apartments. Our kids Attic desk/study space over looked our pool in the rear garden. With respect to using the formal rooms for bedrooms, you will find that once you have your large family/alfresco and the kids have their upstairs space if you still feel you need it, it would make a great office. You spend most of the time there only using only using the front room in the evening for watching movies etc. I have had another play with my floor plan, I think if your wife sees this you may be in trouble, it's a Master Suite, the free standing bath in the window alcove with white timber shutters for sun and privacy control..... Iam' adding a couple of photos of our old Federation which wasn't protected, when we sold it the new owners removed all of the Fret work & posts replacing them with simple timber posts. The front rooms which we didn't use very much once we opened up the rear rooms into a family area. The room with the Bay window had a Baby grand sitting there, we sold the piano before we took the photo. Cheers

HI All - for some reason my lengthy reply a few minutes ago was deleted :-(. I put so much thought into it! So here it goes again. Basically a big thank you to you Houzzers. MB your subfloor ventilation sounds great and Im glad it's fixing the problem so simply. The reason why Im trying for a whirligig solution is that I favour a passive system, however if it doesn't work I'll look into what you suggest Siriuskey - yes to some kind of kit. I've already contacted a guy on Gumtree selling grannykit frames - he says for something to my specifications would be about $4000 for the steel frame alone. Would need to check engineering details - and the liveable sheds you've linked me to seem to have that all checked. Although getting a local Chippie to frame it all up on site - as Twos Co suggests - is probably the most economical option Two's Co - thanks for the feedback and the excellent checklist of processes. I've covered most of the concerns though - I've got the DA based on my own flimsy plans. Because it's relatively small, I was going to work with the builder directly and over-engineer it. I've since engaged an architect to do some handsketches and draft specs, which will be signed off by a structural engineer. It's basically a portal frame independent structure, with a 3 degree pitch skillion roof. The house was rewired and the wires you can see are non-live looms waiting for the extension! The sewer is not connected and that part was never plumbed in. There's good rear lane access, but for the purposes of getting concrete in, I'll most likely get a concrete pump from the front of the house - for $180 per hour they will save time and make the concreting much easier. The existing trench I got dug in because I had an excavator on site installing those lovely large concrete blocks you can see, for the retaining wall (500kg each). But that was 7 weeks ago, and the excavation has got too large, and I worked out for a very similar cost I can make the extension 1m wider, so why not. The existing trench I can fill in with the demolition rubble, compact, and filled with any fill waste. Two's Company, I'm on the fence about removing the existing Bedroom 3. If I thought it wouldn't add to the costs too much, I'd do it. One advantage is that I could then make the whole 9m long extension (Option 2) around 150 - 300mm higher, (ie a step up from the existing house) and thus avoid too much excavation and a potential pond. To answer your question about damp and moisture, the whole house is facing a hill with 7 degree slope, and fixing this has been the main aim of the retaining wall, however the runoff is only likely to increase in coming years. anyway here are a few photos. The site is still so messy because the demolition only happened 2 days ago - Im still tidying up....
