how much to build something?!
Discussion
From memory UK residential build cost is circa £1000 per sq metre (is this correct??).
So a single storey (with high pitched roof) extension of 6.5m*10m should cost 65 grand then right? So is that finished? as in plastered and with working lights?(!!)
Plus, how much ought one add in for the demolition of an existing part of the building (of roughly 2/3 the size) that's in the location of the extension.
Basically i can't afford this at the moment but as you may have noticed from the previous thread the other month i am trying to plan for the long term!
Plus - how much would you assume per meter for stud walling? presumably it's now possible to get a high spec wall (i.e. sound proof board with decent insulation between it)..? how much would that be per metre.
thanks chaps.

You'll probably get lots of "how long's a piece of string" answers (which is probaly about right), but this may be of help (nicked from the H&R Website
I personally think that £1k/metre is quite lean these days, but it will vary region-to-region, spec level etc etc.

^ as you say i am sure it could vary a lot but what you have posted is helpful... and at least it kind of shows the thinking is about right.
the current house(nee bungalow) is block and brick with marley tile roof. it's got glulam (sp?) beams supporting the roof. in the 'new' (aka replacement) section i kind of fancy some sort of different roof support - maybe those metal tied in things (like in barn conversions! 9as you can tell we're at early stages!). other thing is the floor will be concrete suspended floor (we want to be c1m above existing ground level and then have a sort of decked are leading out to the garden which is currently higher (i.e. the back of the house is sort of 'dug-in').
there'll be nothing fancy in terms of a/v wiring or anything like that. the one big difference from normal will be glazing. we'll effectively want the whole of the rear wall floor to ceiling glazed with 'beeny-doors'. i can see it being (looking at that chart and some other stuff) about right for the 'box' but then 30k (or more) in doors and windows..!

actually thanks again!
it led me to this which is also quite anice 'ready reckoner'!:

that's a good site i think. i'll have a look for things to read and inspire/frighten me!

Good luck!
There are so many variables in these things (as you seem to be aware already) that it's very difficult to pin down costs, but it's a start at least, and the theory of 'the wisdom of crowds' should probably apply here (to a degree) as all of the 'variablity' has probably averaged out to arrive at the 'average' figure (if that makes sense).
Sounds like an intersting project - keep us updated - is it quite a new bungalow?

it was built 1984-1987 then phase 2 in 1993ish then again in 2005.in it's context it looks quite 'Portland (,oregon)' (or if being more uncharitable a bit australian!). the joinery is mostly scandanavian and inside as it stands it's a bit 'log cabin'!
what we want to do is flatten the 2005 part (stupid pointless conserva-study) and part of the 1980s bit (currently our bedroom) to build a new box which is half kitchen dinner and half 'lounge'. as it stands it's got one bed at side one at back and one the other side of the living and catering areas at the front. what we want to do is effectively get all the bedrooms at the front/side and then have all the living at the other side and predominantly back - i may well show pics at some point!
then what we'll achieve is views of the garden (over an acre of mature tress and landscaping) rather than only having a view of it from 1 bedroom).
within reason we're happy with costs associated with 'reclassifying' the existing rooms. building the 'wow!' bit is where we're more hazy...
the daftness of the existing layout is actually good because it lends itself to being able to isolate parts whilst reconfiguring it. one of the other key things is that there's a sort of entrance courtyard. this will be filled in as a bedroom. the entrance will move to the existing smallest room which will effectively become a hallway with storage (plus a bit can be chopped off and added to another bit which'll then for a study/playroom).
a lot of people think we're daft but the there's nothing particularly wacky about the house other than the layout. we've been able to buy it dirt cheap because it's got so much land (which freaks some people out), because it's dated, and because the layout needs improving. effectively we'll 'gain returns through asset management'! we want to stay there but you know what i mean. we'd not be able to have something like this if it were already done. it'd cost 135-150% of what we paid.
where we are now is - do we do any inbetween jobs or do we just keep wacking paint on things and save up to do the big jobs. we're favouring this at the moment!

One thing to remember those Sq m rates will be with out VAT as new build house are exempt, house extension are not. I do planning and building regs applications and clients usually I ask how much do I think. I usually use £1100 per m sq and more often than not the quotes they get are there or there abouts.

that's a fair point.btw i am very near mitlon keynes so i am working on the basis of things being 'south east' but i secretly hope that with the law of averages (i.e. we're not in harpended/amershame or whereever) that we'll be at the lower end of 'SE'! it's a shame we don;t have the money now because all the building has stopped in MK..!
