We are considering purchasing a new house but the main off-putting factor is the rather steep back garden and currently it is not child friendly. its about 20 meters deep and 10 wide, and i would say it has an angle of about 30 degrees. I have a couple of questions: 1) I know there are many factors when it comes to terracing gardens but is anyone able to give a very rough idea on cost to create say 3 terraces cross the 10 meter width so that each terrace is level. Are we talking a few thousand or more like 10K, 20K etc? 2) This is a rather wacky one but I also had the crazy idea of having a garden building inside one of the terraces so that there is a door into it, flush with one of the terrace walls! I was thinking maybe something like a shipping container. Above it would only be about foot of soil so grass could grow (or less if we want with artificial grass). Has anyone done anything like this? is it that crazy that its a no-go? Many thanks.
