Bricklaying Question

Depth needed for conservatory foundations

I'm currently digging out for a conservatory, 3m x 4m. It's going to be a dwarf wall (7 course). I'm down to a depth of 1m from ground level (1.2 from dpc) but I'm still in red clay. It's quite firm but damp at the same time. I've asked the local planning dept at the local council but they said they can't advise on it. I'm wondering what depth I need to go to. I'm going to be filling with 750mm of readymix. I'm a qualified brickie but have always worked off plans. Any advice would be good

Cheers

Being in clay, the depth factor is gauged by the presence of trees within a 30m radius. However conservatories under 30sqm do not need Building Regs approval so you can do as much or as little as you feel fit.
Hope that helps

As the other chap said there wont be any regs for this so building control wont want to advise you for free, that's why they wont be helpful!!
Personally I would dig and mass fill a 1m deep and 600mm wide trench to be safe.
