Building behind retaining wall with no footing
Building behind retaining wall with no footing
(OP)
I'm looking to build behind a retaining wall that has no footing but worried the whole lot could collapse. We will engage a structural engineer before the project goes to construction but we are just looking for some preliminary advise so it doesn't have to be redesigned post planning. I left a 2m gap between the existing and proposed as I assumed this would help the situation? I have read about a 45 degree rule from the proposed footing however, as you'll see, this would result in an extremely deep foundation. Any help / advise would be extremely appreciated!

Unless some very unusual situation comes up it would appear that a nearby small building will have no important-effect on the existing barn wall.

Oldestguy - Yes correct... and old stone masonry wall. No the new building is shown in the correct position - The new floor area has to tie in with the existing first floor level. Okay great - thanks for the advice.
Ron - Thanks for the advise. I will consult a Geotechnical when it comes to construction.
EireChch - We are planning do roughly what you have sketched out. I have enough information to press one with the planning drawings now and will consult relevant bodies when it comes to building regs / construction.
Thanks all.

Instead of the 30 degree limit of influence laterally,60 degrees is more common.
