Hi everyone - trawled for info but finding slim pickings...I need to build an elevated patio behind a house on a hill to allow level wheelchair access out into the garden. It can't be deck (horrible to travel on...shakes all your fillings loose !) so i want to lay slabs (probably Indian sandstone or similar). Height to take up is a good half metre...so I'm thinking easiest and quickest way might be beam and block base? What do you reckon - good plan or bad plan? If you have any better ideas I'd appreciate any input! Thanks in advance!
