I am buying a newly built townhouse in the UK that is not yet complete. They have done up the small garden simply, creating a stone path, a terrace and a patio (I prefer top terrace :-) at the end of it. They put down astroturf which I cannot stand, but OH loves the idea of being able to go away and not worry. Anyway, I would like to add another patio/terrace which would mean reducing the size of the astroturf, making good the edge of it and laying either concrete or real paving stones. Nothing too expensive but good quality. The size would be 6' x 5'. Would anyone have any idea how about much these would cost?
