Hi to everyone. I love the website... so much so that I bought Tony's book yesterday.
Anyway to cut to the chase. I'm replacing a retaining wall in my garden which held back a raised lawn about 80cm above my old patio level. My plan is to have a flight of steps up to the lawn from the patio. So that it looks something like this... ----|===|---- where --- are the walls, === is the flight of steps and | are the side walls. The side walls do not project in front of the main walls but the post wouldn't accept ___ which would have made for a better diagram.
I'm halfway through digging the foundations for the main walls but my question is what is the best way of doing the foundations for the side walls.
With five steps I calculate that the flight will run 1.75m in length from the wall and through into the lawn. Do I need to continue the foundations for the retaining walls at 90 degrees and at the same level 1.75m into the mass of lawn and earth that is facing me or can I used stepped foundations to follow the flight of steps.
I'm guessing that the side walls are still performing a fair bit of retaining function - especially at the front - so decent foundations are still in order, but I don't fancy excavating 1.75m into the lawn at the same level as the foundations for the main retaining wall.
All help and advice greatly appreciated.
