Hi guys,
I'm extending an outhouse (single skin brick work) to install a upvc porch. I'm wondering how deep the foundations need to be for this construction? As the area of extension is less than 3m2 its not subject to regs. The soil conditions are hard clay.
I was going to go 8 inches wide and 8 inches deep, but was unsure of where to finish the foootings relative to where the bricks would start!
Also, I'll be raising the floor level to the house (the door on the left of the picture). What sort of depths do I need when I fill in the middle with a concrete slab e.g. concrete, insulation, dpc, sand, hardcore etc?
Thanks!
