The big problem is that the budget is going to be really stressed, so I need to think of all the ways to save money from the start.
Here's what I've come up with so far. But maybe some of these are just wrong ?
- Use a home draftsman rather than an architect
- Group all the plumbing elements together (ie in one corner of the house)
- I've designed identical top and bottom level bathrooms, which are even stacked exactly one atop the other (will this save money ?)
- Many of the downstairs internal walls mirror the upstairs walls
- The exterior is a basic square
Electrical outlets tend to be in straight lines as seen on the plans - that is, sockets in one room are in line with sockets in the next etc. Is this a help ?
- I've done some interior painting in the past so am contemplating doing ALL the interior painting myself
- Are there any new construction methods that might reduce time & costs ? For example, I've seen some TV shows about the polystyrene & concrete 'Beco Wallform' method. Does anyone have any experience with them in Australia ?
- I've also heard that a very well insulated house can be heated using a single efficient wood-burning heater. Is that really a practical (or wise) solution ?
- Call me a barbarian, but I really dislike halogen downlights. One reason is that they're a different format bulb. In my last house ( a rental ) I counted NINE different bulbs types in the house (including two different types of halogen bulbs) ! For the build I'm thinking of a simple single ceiling light in each main room with a door switch. Will this save over multiple halogen downlights ? Are there any other ways to save on lighting ?
- I'm thinking of having no built-ins in the bedrooms. I find most of them are just melamine board anyway. Will this save a significant amount ?
- I'd like a large deck area adjoining the back door for the kids. Can this just be part of the initial concrete slab ? I'd initially just leave it as untreated concrete. Is this a practical and cost effective idea ?
- I'd also really like some sort of large upstairs terrace. I'm thinking that if I make the double garage flat-roofed then I can put a terrace area on top of that. Is that practical ?
- To what extent can I choose and buy all the fittings such as doors, toilets, basins etc myself ? Is that the usual way or just a way to irritate the builder ?
- What is the cheapest family-friendly flooring ? I'm happy to go with industrial-grade carpet. Is it the best I can do on a budget ?
- Ceiling cornices: Are they needed at all ? I once lived in an art deco house where the wall plaster just curved up to meet the ceiling. It was sort of like a cornice, but just smoothed curved into the ceiling. Easy to paint and clean. Does that sound like a good (ie cheaper than cornices) option ?
- Ideally I'd like a double-brick house rendered white in a sort of Georgian style (which seems to suit a simple 'box' design). Is putting white render over brick really expensive, or a decent alternative to a straight paint ? If that's all too expensive then I'll have to go with unpainted brick - anything to be wary of there ?
I know these are a lot of questions, but if anyone can shed light on even one I'd be most grateful.
Thanks

ps: And if anyone knows a good draftsman or builder in Tasmania....
