ground floor extension - how much?

[Cambridge]

I'm thinking of buying a property where the outside of the ground floor (facing the back garden) needs renovation work. A very bad, small 1970s extension is causing damp problems and needs to be completely altered:

(i) removal of outside toilet, and extension of kitchen space to fill new space

(ii) new kitchen units (& plastering / painting of new kitchen area)

(iii) EITHER addition of French doors into garden, OR small addition of small conservatory (6m x 1m)

(iv) treatment of damp problem arising from former kitchen

(v) knocking down of (non-structural) wall in between kitchen & dining room

Even with this scant information, could anyone give an idea of what price range I ought to be looking at? Any thoughts much appreciated, thanks!

Sizes?

The kitchen is currently approx 2.5m x 3m, and would grow to 4m x 3m.

the outside wall of the back sitting room (needing French door / conservatory) = 4m

These are rough guesses. But tell you, I think, that the space isn't huge?
