We're trying to plan out and price up an extension and as a starter
for ten I've been looking through "The House Builders Bible" by Mark
Brinkley. It's a good read if for no other reason but the little
rants he has.
I have a sixth edition so I realise the cost tables might be a bit
wrong, but making allowances for inflation should at least help a bit.

At least that's what I thought. I calculated some costs and then got
a builder in to quote. There are some unknowns at the moment but the
builder came out over double the price I'd calculated. Even allowing
for the inflation and the builders margin it still seemed waaaay out.
So I wondered if the tables etc aren't really applicable to
extensions.

I see that the seventh edition has a chapter on Extensions.

IIRC Mark is (or was) a poster on the uk_selfbuild list, maybe get a
reply from the horses mouth?
