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/

Rich B,

PM what your after, and I can do you some numbers tomorrow if you like.

Do you read Homebuilding and Renovation?

£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.

You cant quote figures like that without knowing what the spec is going to be.
Theres to many factors to cost in.

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 independant 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.

[mrmaggit]

Half a mill.

Edited to add, let me know how far out I was when you've totted up all the bills.

Have you enquired about planning permission for the site first?

That makes a house like my 3 bed semi (about 1000 sqft without including the detached garage) 110K to 150K to build.

That's pretty much what my 3 bed semi is worth in this market!

Does this figure include the land? It seems surprisingly high.

Ahh. that's good.

It would have been quite annoying finding the plot, but then not being able to build on it.

That looks quite handy, if you haven't already seen it before.

We've worked on places at £350/ft and we're just talking to someone projecting £700/ft

The amount of variables are phenomenal.

James here:

A STANDARD build wimpey esque house will cost about £32000 for a 2 bed terrace to £70000 for a 4 bed detached. This is finished includes kitchen and bathrooms etc. It EXCLUDES externals drainage fees roads S106 land etc.

We would expect to do a full site including everything bar land for late £70/ft to £85/ft dependant on spec and unit type.

Apartments and 3 storey increases costs as well as high spec finishes.

Hope that helps.

[Marcellus]

is this habiltable space that you're talking??

Over here it works out to be about €4,857 per m2 habitable or €2,266 per m2 total.

Both figure include 809m2 of land...

But I guess I'm also paying for the view;

I would suggest you get Mark Brinkley's Housebuilders Bible.

Are you going to self build? Saved me a fortune, but I had to quit my job.

My ordinary 3 bed semi on an ordinary estate in an ordinary town is just over 1000 square foot. This is the total floor area of the ground floor plus the total floor area of the upstairs floor.

Those prices would make a house like mine cost between 350K and 700K.

Is this for an architects flight of fancy in central London or something?

[Plotloss]

350/ft was a very high quality apartment build in Devon.

700/ft place is in Central London, spec is out of this world.
