Hi,
I am going to build a patio area down the bottom of our garden. As the garden slops I want to build 4 walls so the patio as even height. I intend to fill the 4 wall with the spoil from the footings and rubble and MOT to fill it up. The patio will be 7m x 4m and the wall height will be 50cm.
Questions:-
1. Do I need a single skin or double skin wall?
2. Based on the above answer, how deep do the footings need to be?
Thanks in advance
Ian
