DIY Garden Levelling and Turfing Advice

Hi All,

I've recently bought a new build and the lawn was terrible, and still is! The lawn is uneven, full of weeds and has a massive amount of rubble/stones/glass buried in the soil, which I assume is a house warming gift from the builders!

I started by applying weed killer on the whole lawn to kill the weeds, and now I'm in the process of using an electric tiller to churn up the ground to try and level it - which so far has been difficult to say the least!

Now I thought to myself, before I continue on this self development journey that I should seek advice and see if my plan is feasible or even makes sense!

In my head the next steps are:

1. Finish off tilling the ground
2. Rake out the large stones which there are plenty of! Also the dead grass / weeds.
3. Level the garden (Not sure how!)
4. Add top soil to perhaps help with levelling and;
5. Finally, decide whether to use turf or seed to finish off the job.

I would appericate any advice or suggestions and if there any shortcuts that would most definitely help!
