If you've had a patio down it will have been laid on something, sharp sand and concrete is the usual.
You need to remove as much of the foundation mix as you can, the acid in the mix isn't good for grass.
Once you have removed it you will need to open up the soil, digging or use a rotovator as the soil will be compacted.
Once that is done, leveling, then you can choose between turf or seed. Seed is cheaper, turf instant.
Also if seeding, how much sun will it get, will depend on which seed you choose.
It's getting to the perfect time to sow seed, so you need to start about now if the ground isn't waterlogged.
