building cost for extension

"finished build" being the structure, doors, windows, plastered out etc...then yes and if its considered amazingly cheap, it would explain why the guys I use are always very busy & able to pay the bills.

I just draw the plans & when asked, price it for the customer

Is that a VAT inclusive price?

Hi snowmen
Your quote from the builder (if ex VAT) is roughly £100 per sq. Foot. I don't know what else is involved or how simple an extension it is, but I would suggest this is a wee bit on the high side.

does anyone know what the average price of building an extension on a house in northern ireland is in square metres?


I take it a 2 storey extension would be roughly double the price of a single storey extension.

thanks.

Now in my way of thinking the same foundations and roof will be needed whether it's a single or two story extension so hopefully you are wrong about double the price.
I am no expert, just my logic!

Depends, are you a tax man (no it's ex. Vat)

We finished a 2 storey extension within the last 6 months and it's just fantastic. Our labour costs were lower than budgeted but the cost of materials has soared in the past couple of years and took much more of our budget than anticipated. My advice, for what it's worth, would be to allow at least 30% more than you think the job will actually cost - I wish we had!

did you use a building contractor to do the job or did you do it yourself?

LOL.

So £50 + VAT per square foot = £60 per square foot.

So not really £50 a square foot then.

Have to agree there.

Unless hes furnishing it out too.

another question for you - when you are planning the extension when do you get quotes from builders. The quote I mentioned above was a rough guestimate but when do you get a proper quote that wont change a great deal?

Hi Snowmen

We had been toying with the idea of doing a double side extension, we got some rough plans done from an architect f.o.c. and went to 3 builders and for a 6x4m extension 2 storey we got 3 quotes just for a shell - £30K, 35k and 50K, we still would like to do it but are worried about going over budget and being able to stick the disruption

good luck whatever you decide

550 sq. ft extension has been "quoted" at £25k
£25000/550 = £45.45 +20% vat = £54.54 (closer to 50 than 60 )

The builder reckons that if the customer went daft with tri-fold doors, triple glazing etc... then they could expect to pay £28k +VAT

As a "money saving" forum, I'm simply passing on the info :beer:
