Laying a new lawn.

[Staglemon]

I am laying a new lawn in our newly built house.

At present all that is laid is what I think is builders soft core (small stones in pink gritty mud) with pebbles laid on top of that. I want to dig up alot of this and lay a lawn. Thing is I do not want to end up with a huge mud pool because of any problems with drainage.
The garden has a slope off at one side and a rise on the other so in theory the water should just go acorss it and down the other side.

My question is how far should I dig down and lay soil to put the seeds on? I would like to end up with a fairly good quality lawn.
Also is it just a top soil I need to add or does anyone reccomend something else?

Drainage won't be a problem if the lawn is sloped (providing you don't have any dips).

As to actually laying it. there are loads of guides out there such as :

you need to establish what the soil is under all teh builders crap. If you are on clay, then think of it like a draining board. the water will run across the surface and down, but will end up somewhere, ie the bottom of the garden, so some drainage may be required there.

best option once the drainage is sorted is to lay the lawn on a good layer (at least 100mm) of sandy loam. Its what decent turf is grown on and it will allow you to get the lawn perfect.
