Hi All
I want to raise our patio so it reaches up to the patio doors we had
fitted.
We don't want to use decking.

As far as I can work it out, I'll build a retaining wall around the
intended
patio area, fill it with rubble and crushed hardcore then lay slabs on
top.

It will need to be four or five feet high.

Can anyone recommend the depth of foundations, thickness of the wall
(dense
blocks) etc and can I use any of the soil removed for the foundations to
fill inside the raised walls.

Do I need to talk to Building Control or Planning.

Thanks
Roger

Wow! If patio is 10 by 10 feet, say, that's around 500 cubic feet of soil,
fill, rubble, what have you. Not only a lot of work (Hire machinery? Access
to that area for a dump lorry etc?) And will require proper compacting to
avoid settling. Handling slabs five feet above ground! And unless the ground
slopes usefully a massiive 'pile of dirt' which can asorb water right
alongside the house structure? Make sure it is drained in same way that
embankments are?
Personally I'd not tackle it that way but you know the property.

PS. If not machinery accessible; wheeling barrow loads up an incline! Whew!
Even 'building' an inclined ramp 'up' five feet is quite a job (and space)?
Or 1000 to 2000 one half to one quarter cubic foot bucket loads of 'fill'
lifted five feet and dumped (by two people?). But can be done as a fitness
project!
