Have dug a hole....created my form for the foundation slab, taken delivery of gravel, rebar, cement and concrete mix to make some progress this weekend.
Problem I'm having is sourcing hollow blocks - apparently suppliers in Scotland have to take these by the truck load so noone stocks them.
I can get 7n blocks 440x215x100. Would these be stable enough to hold the weight?
Should I double up and put them on their sides or could i Get away with a sort of m shape base with some support down the middle?
Any thoughts would be appreciated.
