Sorry if this has been covered in another area of the board but I couldn't find it.
I am about to embark upon a project to make our back garden a more usable space. Currently it is flat at the top for approx 3 metres out from the house then has a slope down for about 3.5 metres with a change in elevation of approx 0.6 metres. The overall width of the garden is 11.5 metres.
What I'm proposing to do is to build a wall and to backfill the space to make aarea level with teh house for a lawn on the left hand side. And on the right dig out from the edge where the slope starts to the back creating a sunken area for a deck which will be joined to a deck at the top via stairs.
The problems I can forsee/need advice on are as follows:-
1) The boundary fence between my property and my neighbour over the back is 1.5 metres high. If I build up the left hand side would I be able to put up a fence on the part I have built up and if so what height can it be?
2) Would I require planning permission to do the raising of garden?
3) Would the wall have to be single or double skin?
Thanking you in advance for any help.
