Estimating Cost of New Build House?

[RichB]

Hi Chaps, does anyone have a good estimator tool I can download or use on-line to roughly estimate the cost of building a new house. I don't want to go into detail of how every room will be finished but a bit more than the finger in the air £150 sq ft job. Anyone? Thanks Rich...

Thanks, looks like that's something you buy, I guess I was looking form some freeware or something free sponsored by a magazine?

I found this but it's an American site so the costs don't relate to a UK build, it talks about air conditioning and furnaces! http://www.building-cost.net/

£1200 + per m2

OK so a 275 sq m house would be £330k but doesn't it depend on quality of finish etc.? I assume this is for a high quality finish.

Have a look in one of the many self-build magazines, they have sections that give you a guide to costs.

When you get to working drawing stage, there are many ways of getting material costs, but if you take an outline planning drawing to any of these people/places, expect to get it back in the form of a paper plane, there is not enough detail on them.

I was at the self build show a few years back on the independent merchants stand when a chap came up with one of these drawings, asking "How much to build this"? I then started to run through the drawing with him, he soon realised what I meant by "not enough details".

Whatever the initial costs, budget at least another 30-50% on top. Do any alterations at the paper stage, not when the builders are there, unless they suggest a cheaper/better solution to some details (it does happen).

Spend the money on the shell, you can change fittings later if you wish.

Thanks for this... I guess at this stage I'm trying to work out if I can afford to get something built that matches what I'm looking for. I've been engaged in a normal sale & purchase process and got a good offer on my house, now the chap selling the one I want to buy is buggering me around. My wife's found an acre of land she's interested in so before I engage in conversations I'm trying to get some basic information on building a high quality, detached of around 3000sq' with a triple garage of course! I've looked on the BICS web site and found a cost of "re-building" model, but that's not new build.

Have you enquired about planning permission for the site first?

For the OP, I'd suggest would work on £85/sq ft and assume this includes for something like a 10k kitchen & 'average quality' sanitaryware, so just add from there what you think you're additional costs will be..

Thanks...
