Party Wall Garden Boundary

I have removed hedges from my garden and plan to place a retaining wall in their place and backfill with fencing on top. Do I need to inform the neighbours with the party wall act notice?

It will be on my own boundary and the wall itself will not be visible to the neighbour once complete as it will be built behind an existing fence, which I also own?

No PW notice required

Strictly, you should get their permission to put any foundations across the boundary, but most people would not bother or just do a narrow strip.
Hi Woody,

The foundations have been designed by a Chartered structural engineer, would that suffice?

It would not help in terms of permission to build across the boundary, as that is a different issue to the design of the wall.

If you get on with the neighbour, then they should understand that you will (may?) be disturbing a bit of the bank to do the work, and you will pit it all back afterwards. The foundations may not ever be an issue in the future.

Hi Woody,

It is just before the boundary which means their land will remain the same and no access will be needed.

We'll be excavating downwards to hit solid ground, but again it won't touch their land.
