Just to confirm I have taken the great ideas presented here as advice only and have no intention to do some dodgy diy reno's. With the exception of a couple of quirky exposed timbers as you can see in my pictures there are no other exposed beams. As you can also see from the pictures there is a large roof space on the right (east) side of the house but the ceilings themselves are flat with a slight dip on the north wall. Based on my own personal experiences I would have to agree with Two's Company that there is a tendency towards rendered brick in WA (although there are still many exposed brick houses in my suburb) while double enclosed double garages are also highly desirable. I would also agree that toilets within the main bathroom and non traditional laundries may be considered unusual by many (but not all). Ensuites with toilets however are still very common. Also due to the nature of our work we would prefer the laundry separated from food/kitchen area. For a 4x2 house it is only around 155m2 excluding carport/alfresco which makes the rooms feel quite cramped, hence the desire to open up the family room. However, as Two's Company suggests we will need to first get a builder/eng in to check load bearing walls etc as this will undoubtedly affect what we can achieve within our budget. Having said that I still excited by many of your ideas and with luck hopefully can work some of them into the budget. Cheers all :)

@Michael Smith - Where do you start? Similar and in addition to Dr Retro's comments, my advice as a starting point for any project is always the same: define your project requirements and nominate a budget. All decisions moving forward will derive from the balance of these two elements within your particular context. you need to refocus on the front end of the process, and set aside the backend construction for the time being...Since you have had no prior experience in this area I highly recommend you invest in experienced professional assistance with the process. It's a given that this type of project (involving building extension/structural adjustment etc) will require building approvals and/or potential planning approvals that require a process of design and development of professional documentation accordingly. Unless you have had experience in these types of things recommend you don't try and manage something like this unless you have a lot of free time, up for the task and are will to engaged/committed for a rather steep and potentially expensive learning curve. False economy in this area is a significant risk and easy trap to fall into for the inexperienced in this area. For something of this scale an appropriately selected builder will integrate the project construction management far more cost effectively that you can achieve independently as a newcomer. This general type/scope of project could be anything from 3-6 months in construction (depending upon the builder/circumstances/detail and whole lot of other factors) but you're getting ahead of yourself with this as first things first you need to establish the project scope and work through the process of design and documentation appropriately for any applicable approvals. If you're interested in further information please feel free to contact me directly - we can similarly service projects of this nature in the Melbourne area.....always keep in mind that there are different levels of professionals and you need to work out exactly what you require in this regard. Are you requiring higher level design assistance? Or do you just need someone to "draw it up" as you know exactly how you want it to be, and can get away with a drafting service.....questions for you to think about and work through/research accordingly..... @anotherbird - this stage can be particularly challenging when you have designed and documented, and then are left on your own to sort through and compare the "apples and oranges" quote differences, and it's not straightforward. I think here it depends on the builder you select. An experienced and competent builder should be able to have some of the things you've mentioned integrated into their process such as the building permit, and also providing advice as to the construction scheduling and how the decisions of finalising the kitchen design etc will be coordinated into the job. Sometimes builders want everything designed and documented prior to starting, others are more flexible and have the capacity to work from contractual allowances and refer you to//utilise their regular tried and tested subcontractors/suppliers to pull it all together collaboratively and sequentially. My advice is trust your instinct with the builder and go with the one that you feel you can work better with, rather than the one who is giving you the best price...the project will ultimately cost what it will cost, and more often than not it's better to pay a premium for less stressful build process with an operator that is tuned into your particular circumstance and needs, rather than go with a guy who might be cheaper but is more about "smashing it out" for lower cost and putting a lot of the responsibility of coordinating fit-out aspects yourselves.... hope this helps Best of luck with it all to both of you :) PD

Thanks for the advice team. So the house is block work on a cement slab, but when we did our renovating in the bathroom and had to cut through and re-lay the floor in the very small bathroom we noticed that the slab was incredibly thin and had no reinforcing. The walls have some cracks however we did have the building inspected when we bought it and thought we had a solid shell to start with. (Its brick and cement we said - what can go wrong?!) Our house is not in the flood zone. There is an asbestos ceiling which has also complicated matters a little - everyone who has quoted on the job has vowed not to disturb it - but I am not sure when you are walking around up there and pulling the original roof off if this is actually possible. The roof is a flat cliplock roof with no crawl space at all, so the ceiling is on battens that are attached to the rafters. The block of land is 822 sqm and will be worth about $130 000 if the house was demolished. (Demolition is set to cost around $30 000- due to asbestos etc) We have spoken to an architect who has told us that it may be possible to reuse our kitchen, the solar set up and some windows, but if we try to force the project to reuse all of our windows and doors it could end up being counter productive. So if it happens to fit we might reuse. I just spoke to a real estate who are telling me that in our area a small new house (3 bedroom) will not reach the $300 000 value point - so it may be impossible to reach the right formula to allow the bank to lend for a rebuild-

I'm going to thro a wobbly into this mix: Have you thought about going two storey so there is some outside space for boys to play? Looking at your site plan play is either in the pool or the street! Master bedroom, with all the robe you want upstairs and a kids free zone! Or boys rooms above as long has they do not own hob nail boots! Then do not use ALL the extra space on ground for your film works! Seriously this would give you some breathing space and some real outdoor living area to enjoy which you can do in Ipswich climate. Four beds separate bath rooms and stairs above with a laundry chute. Down stairs a real laundry (proportional to a five bed house) A powder room with shower for after pool. Your study of a size worthwhile and theatre room for family second sitting room as well as clients. The master can then have better sized robe, all the bits you want in ensuite including separate loo (lovely idea) but please on outside wall with window. Personally, I'm not one for two storey but in this tight site I think it would be much better. Good Luck, Margot
