Excavating close to neighbour's house

[Al@n]

Do a narrow trial hole with a narrow spade and find out where the foundations are ?? Like woody said it's a downward force rule then apply the 45 deg rule. If the floor level inside is high however the house was designed to have the soil there permanently...regardless of rules and health and safety common sense applies also..ie.the property has had that soils up again it's lower walls for many years....... Good luck with it

I did do a test hole approx 1 metre deep and hadn't hit the foundations but have 0.5 metres to go before i get to ground level

The air bricks are approx half a meter above the soil

Mmmmm.. Playing devils advocate.. If I were your neighbour I would not like it..and be worried..They may even have a right to demand you appoint a chartered surveyor. The 45 deg angle is the rule of thumb however... Up to you.

I've decided to park doing anything on the garden for now, and considering building a retaining sleeper wall to support some of the soil.

Not sure how much soil i will need to retain, whether its 1 metre, 2 or more!?

Could you explain further regarding the 45 degree rule?
