Hello! I’ve recently moved house and finally have a garden - hurrah! It’s quite small and bricked however we want to level it out so it’s on 2 levels rather than 3 - we’ve done quite a bit already however the problem we have is that we’re worried the top level might be supporting / holding up the back wall - is this something we can or should try ourselves or should we get in a professional... ? The below are some before pics... And this is now after getting rid of a few bits and cutting things down/back. And this is on the right hand side ... no idea what they were thinking?! ... What we want to do it get rid of the little wall and make the grass reach that back wall so it’s flat... Any help or advice??? Thank you!
