Browse Forums Building A New House 1 Aug 06, 2009 5:01 pm Hello all ! I'm new here, I found this forum terrific !! I'm in Sydney metro area. I'm planning to buy a property with a 546sqm slope land. Frontage is approx 12.5m, and approx 45m long. The existing dwelling is a 1920 californian bungalow about 90sq meters in size From the contour map, there's approx 4.5m fall for the land from end-to-end. ie. for a typical project home length 20m, I'll be expecting a 2m fall for the new construction. Please refer to the following picture for an illustration (Street on the high side): http://users.tpg.com.au/adslb6j9/Contour1.JPG Question: - How much will I be expecting for the knock-down? it's double brick. - If I'm going to build a project home, approx how much would be the site cost? ie. for a typical single storey 20sq project home... Thanks very much for your kind help. Your help is much appreciate because it affects our decision on purchasing this property. Cheers ! Re: Question about Slope and site cost 2Aug 06, 2009 5:22 pm Hi There The drop on our block from front to rear was 1.8 metres, so similar to yours. The site costs ended up at ~$60K. Half of that was due to the slope - more concrete and they brought in a lot of dirt as well. Not what you wanted to hear I know. Hopefully you manage to get a much better deal. Good luck. Franco Re: Question about Slope and site cost 4Aug 07, 2009 9:55 am Firstly great little contour map you have there. Created just in excel? I think the options would also be to look at a splitlevel. Sometimes the additional costs of doing say a 1m split in the middle of the house is a much more viable option than bringing in plenty of soil for a standard cut/fill. We ended up with a 2m fall down the foundation area of the homepad. Our slope is not unlike your slope. We have 8m all told but over a much longer distance. Our total site costs were $9.5k, so you can already see the massive differences in costs. Soils and environment differences like drainage etc can vary the costs dramatically. So I think without perhaps getting some quotes from builders you will not know any approximates.

I'm not going to answer your question about site costs, as we've gone with a small local builder and he just quoted us a price for the overall build. . . but I will ramble on a bit about other stuff. We're building on a slope too! We've got approximately a 10% slope from left down to right, as well as a slope down to the rear. We're lucky that we've got an acre of land, so we had a bit of space to play with. We took our ideas (and my 10th attempt at our floorplan) to our builder's drafter, and he turned it into a split level with garages underneath. Take a look at our blog if you want (it's in the signature at the bottom), there are the floorplans, elevations and a contour survey. We naively bought our land thinking that we could build a house on it for the prices that the project builders quoted online. . . we thought we'd be able to build for $200K. . . now we're building for $400K. I think we trudged around just about every project builder in the universe, and very few of them seemed eager to build on our slope (which may have been due to the kind of house we were looking at). It might be worth getting some quotes in before you actually buy the land? Some project builders want money from you before they'll even quote, but some will give you the initial quote for free (we got one from Masterton for free, don't know if they're still doing that). Personally, we like the flexibility that comes with building with a smaller builder. . . we're not bound by "inclusions", we can buy whatever we like in the way of bathroom accessories, appliances, flooring, etc. (and have been busy on Grays Online getting some super bargain kitchen appliances!) We also get a custom-designed house instead of trying to make somebody else's plan fit our land. Out of interest, what's your suburb/area? (If you don't mind) Re: Question about Slope and site cost 6Aug 07, 2009 12:29 pm ozzroo: Thanks for your info. How can your site cost be so low given the amount of cut and fill ? What a great house ! Your elevation diagrams give me a clear understanding of how all the things work. jodge: Thanks! I'm looking at lower north shore. Re: Question about Slope and site cost 7Aug 07, 2009 4:59 pm Yeah the dotted line on the first elevation gives you a good idea to the slope. It's funny as the pics of the actual block at the bottom of the blog don't look that steep.
