Budget price for an extension.

I am looking at purchasing a house which I would want to put an extension on the rear, width of house is about 22ft internal and I want the extension to be about 14ft wide internal.
Could any one give me a budget price to build either a single story or two story extension 22ft long x 14ft wide (internal sizes).

Hi. I don't know where in the UK you are. I'm in glasgow
When submitting building warrant applications I use the cost of £1000 / m2 for single storey and £1500 for 2 storey

it all depends on the materials you would use ie; brick or stone on the outside .The inside walls would be breeze blocks.Would you be wanting just a shell? (Foundations,external wall,internal walls,slated roof) or would you want a complete extension with all the fittings. would it be a single story or two story.
