I want to build a 2ft raised area in my garden, about 5m x 15m, which will have a barbeque area and an area fo seating.
Do I have to hard fill this area or can I make concrete foundations build up with concrete blocks, floor joists and topped with some kind of paving (creating a hollow void underneath)
What's the best way?
