Advice on new-build garden
I am buying a new-build house, which will be ready in a few weeks. The rear garden is left un-turfed and doesn't look ready for turf. It is very compacted and there are rocks and construction rubble in it. All we want to do is lay turf over the entire garden - but the area gets quite a lot of rain, so I'm keen to help drainage as much as possible. It's approximately 7m x 7m What would be a simple/low-cost (DIY as much as possible) plan of action to prepare it for turf?
