Topsoil on top of patio then gravel?
We are looking for some advice please! We have dug up the small lawn in our garden (the previous owner built a brick shed and the soil he dug up created these very odd mounds of earth) we need to level this dirt area now then plan to put gravel down. there is patio consisting of small paving slabs leading down the side of the house and along the back before the area where the lawn was. We want to gravel all of this area also and use big stepping stones however we are unsure of a few things. Firstly the patio areas are uneven, they actually slope towards the house currently which isn't great for drainage so understand we need to have a slight slope away from the house. We thought using the topsoil we have dug up to bring the levels up would be a good idea- can this be put directly onto the patio areas then put the gravel on top or should we remove the patio slabs first? Also will it be ok to build soil up next to the house on the two sides to make the level high enough to have a slope away from the house? Confused!
