Help with garden!

[Thegift]

Hi, just had a new extension done onto the rear of garden.

Money is tight now so going to have a crack at the garden myself. It it's all out of level and bumpy everywhere as you can see from photos.

As you walk out of French doors planning on having a sleepers stepping up onto the grass. I've got a fair bit of clay which was dug out for soakaway. As I've got to build the whole grass area by a few inches is it ok to level the clay out directly on top of grass then soil on top followed by turf?

Any tips advice?

Using clay to build up the levels will be fine with topsoil on to then turf, just rake it as level as you can then use a scaffold board or any bit of 4x2 to get the best even surface for the turf.
If I were you , I would fit some aco drainage channels in front of your patio doors because of the slope down to your house before you lay a patio.
