Hi: recently did the footings for my (mainly glass) extension, in heavy clay ground. Building regs told me to go down to the bottom of the house footing - 1.2m! (= a lot of clay muck away). Not saying your project would need as much as it is an outbuilding but I expect building regs round my way would say for a single storey go down till you hit chalk (1.2m). I think it really depends on ground conditions on the site. I'd put a proviso on it saying contractor ( i guess you) needs to dig a test pit on site prior to starting to determine ground conditions.
Totally prepared for the likelihood we will be digging out lots of clay
If the tree is tpo then you may not even get started that close to it.
Have the clients got planning permission?
If so there may be stipulations in it?
As far as I'm aware there aren't any tpo's at all. House in the country
thats got too much potential to go wrong and cost money to put right. for the sake of a few hundred quid i would get an engineer involved to spec up the foundations. if youre on clay youve got shrinkage to take into account and possible heave with it as well may even be better to look at a raft foundation
He also suggested speaking to a structural engineer. Glad I have one as a client and another two I can call on
I will keep you all posted on what happens
