July 10, 20224 yr My SE just gave me a generic cut & paste footings details, so I thought I'd try and design it to new regs. However what a nightmare to match it to existing levels. I was digging a test hole today in 30c and it just got me thinking about it and I needed a rest. I could make the PIR 150mm but what do I do about the 75mm gap under the slip brick? I guess I don't even need the foundation block, could subsitute for 2 blocks or remove all together?

July 10, 20224 yr Author I've managed to get it much close by using 140mm insulation, I'm still 10mm out on the inside wall.
July 10, 20224 yr just get the bricklayers to bump up the course of block under the beam 10mm and block then you have it.
