how much do extensions cost?

[petemurphy]

roughly! i know piece of string and all that but say this house as an example to put a ground floor extension into the garden to make a huge kitchen with fancy door out etc - roughly? 30k 50k 100k?

ie to end up with a kitchen similar to this:

35k + vat plus kitchen fit.

That's pretty much on the money. Did a similar thing in my house though it was 3 years ago now. Knocked down conservatory then knocked out kitchen wall, put up single storey extension (6m x 5m external dimensions) and re-did the kitchen.

cool thanks

some professional will quote £1k per m2.....but dont do it. there are much cheaper options. I built an 80m2 extension myself after getting quotes that were way out of my price range. the whole thing has cost me about 45k (although i am yet to install the kitchen). my advise.....get hands on. Its amazing what you can do yourself, or what favours you can get out of people if you ask around!

I should be so lucky. More like £1500 plus.

Sadly in my case it isn't and I cannot.

Hey we charge a basic £1200 per sq meter of finished floor area .
if you wanted top end finishes or Oak bi-fold doors etc then the price increases to reflect

Whereabouts in the "South", by the way?

We have a 1930s semi refurb project (including total re-wire, re-plumb, knock through + new kitchen, some windows and doors, re-plaster etc) in North Surrey/extreme SW London we're just starting out on...

Starting in 2008 I built a 4 bed / 3 bath bungalow of 190sqm with oak doors, floors etc. . . . . . Not mega high spec but still very nice and did it all for under £100k.
For that I did all the project managing and sourced best deals on all materials and trades my self. I did the internals other than plastering and CH install. I guess it all depends how much you can/will do yourself as was mentioned above.

I did this http://www.pistonheads.com/gassing/topic.asp?h=0&a... which is virtually finished now bar the spare room ensuite and garage ceiling for about 35k to date, I have done a lot myself though and it has taken nearly 18 months.......

Hey guys sorry for the delay w

We are based in southampton and work all over

[Gaspode]

Would this figure per square metre idea apply to an extension which went upwards as well? We have an existing single-storey extension which is our kitchen, it's about 4m x 6m. If we were to have it extended up another 2 floors, would it be reasonable to expect it to cost in the region of 24 x 2 x 1500, so 50k or thereabouts?

[Neil - YVM]

Assuming no further footings are required, the cost /m2 should be slightly lower. although there will more scaffolding, but still would expect it too be less.

[F1SERB]

Yes you are correct we price as a guide the square meters x no of floors
ie 10x10=20m2 x3 floors=60m2 for pricing
However the meter price comes down with quantity
