When we had our conservatory built last year they dug down about 1m! Although our walls had to be about 1.2m high to get the conservatory floor level the same as the house floor.

sadly i belief as we speak, conservatories are exempt from the buiding reg's and this can lead to a lot of dodgy work going unchallenged. normally the footings have to sit on solid clay and building control would like to see footings 1 metre deep to ensure they remain unaffected by natural ground water- water table ( differential movement winter/summer)
far better and wiser to spend more time and cost putting proper footings in, than watching your lovely conservatory develop cracks or movement in a few years time. equally important: when you come to sell your home you want proof the conservatory is an assett and not a liability.

From what I remember, this stupidity of 1m deep footings came about from insurance companies after 1976. A small number of houses moved, MOST didn't, but it didn't stop the "ignorant ones" cutting of their heads and doing chicken impressions. I live on sand. It doesn't move, lots of houses around were built without any foundations, and they haven't moved for over a hundred years.
Houses can be several hundred years old, they weren't built with metres of foundations either, they were built using timber frames that could flex without collapsing.
If people stopped using CEMENT they probably wouldn't get cracks. Houses with lime mortar don't suffer much. Our house is built in two bits. One is 120 years old, lime mortar, a couple of cracks in the plaster. Foundations about 12 inches deep. The other bit is 20 years old, cement mortar (it would be better, so the brickie said) foundations 3 feet deep and cracks all over the place.

You don't live in a beach house do you ?oilman said:
100% agreed with you,my property (1902) footing is on 2" slab approx 18" in the ground !!! I have put on extension on the back with 1 metre footing and now showing a slight hairline crack and still not on my original property !! I don't like cement as its show no flexibility.
