Block work workshop footings ?

[markus2025]

Hi guys so im wanting to build a 4mx 3m by 2.5m tall single skin block work , workshop in my garden ive a 100mm concrete pad thats been down in my garden awhile

the building will be around 12 inch away from my neighbours boundary wall
from what i can gather i wont need planning permission but seems im likely to fall into building regs if it gets flagged due to how close its going to be to the boundary


for the building im looking to do , do i really need 700mm concrete footings... or is the chance that the 100mm pad ive had down for years would be fine to build straight onto of...

Do you want to risk having to rebuild it?

Dependant on your soil and presence of trees you could be looking at >>700 if following NHBC guidance.

<30sqm you don't need BR but you do need fire resistant construction.

I wouldn't chance 100mm slab if t'was mine.

It seems you do need Building regs even if its under 30sqm if its going to be less then 1 meter from a boundary
I dont want to risk a rebuild no...

But i also dont really want to break out all the pad thats in and have to pour mega footings
