Great, thanks @markc, good to establish it should be ok to do there
Now, down to the detail - do you have any pointers at all for how we should do this? Should we be chiselling out brick by brick, removing the soil in the shape/measurements the steps will take, building the wing walls (with bricks or maybe sleepers, as we have no experienceof brick-laying?) Then adding in the sleeper steps?
Any advice to help me get started would be AMAZING - Thank you!
