Hi i am doing a small extension and then extending existing patio to have same tiles as inside and same height. The remainder of the existing patio has slabs on approx 100mm of concrete slab. This comes about 2.3m from the new sliding doors, then there is a approx 2.2m of grass and then falls away through flower bed to a level area that then slopes down the garden.
The new patio to be level with inside needs to be approx 200mm above existing patio it will come out 6.75m. The patio will be 8.5m across the other way.
My plan was to dig out the grass and lay 100mm type 1, where the garden starts to fall away put in a retaining wall and then put another wall 2.5m further out at the end of patio with beam and block on top to provide a storage room underneath. The end of patio would be approx 1.25m above lawn. Could i just lay slab over existing slab and type 1 and over block and beam to provide level for tiling? What height of concrete over each element, existing slab, type 1 and block and beam? Would i need rebar in slab?
Theoretically i would need planning and a balustrade but i wanted to grade the existing lawn up to patio, I would fill in the flat part of the lawn in front of new patio before it falls away again i wanted to fill this flat area so constant angle lawn to patio? I estimate angle of fill would be approx 30 degrees.
I hope this makes sense? Any thoughts suggestions most welcome.
