We moved in last December and are now starting to direct our attention to the garden.

No idea of the history but for some reason the flags in the back garden have been laid as can be seen in the pictures with a slope up to the house wall. I am assuming that the DPC is situated at the joint where the brick colour changes so levels seem ok.

The decking has replaced a conservatory that was dismantled before we owned the house and am trying to decide if the patio should in fact be level with the point where the flags meet the wall (this would seem to be confirmed by looking at the gulleys etc.

If that is the case, can we lay a new patio over the existing flags with suitable base material laid in order to raise the overall level to the point where the flags adjoin the house wall, or does the raised section need to be dropped (but that would necessitate lowering the gullies and grids in order for them to be flush with the flags).

Hope the above makes sense. Appreciate any advice please.ImageImageImageImageImageImage

You can raise the level of patio to those gully providing it's 6" below DPC.
Seems a funny setup there. I might guess that you patio is falling towards the house and originally there was some kind of gravel border where those angled slabs are?
You can't really go top of existing slabs. Wont take a couple of hours to rip them all up anyway.

Can you change direction of fall if building levels up a few inch? Away from house? Plenty of drainage there if not

Looking at decking patio does appear to be falling away from house anyway.

Thanks for the replies, as I say I don't know the history so no idea why the foam has been used.

The DPC is where the change in brick colour can be seen so laying new slabs from the level where the inclined part butts the wall will give us 150mm below DPC and will bring the new level up to where the gullys are so that looks like the way to go.

Thanks again

Thanks, apologies for the misunderstanding I do not now intend to lay the new slabs on top of the old, just take the point of contact where the existing patio meets the wall all as the correct level for a completely new installation.
