Raise garden and lay patio against side of house.

[twentytwenty]

My house is built into a hillside and I am wanting to raise a couple of feet the side of the sloping hill so that it is level and make a usable patio.

My question is. As I will be infilling with soil and rubble against the house. Should I be doing anything to treat the side of the house to stop water ingress etc (building a block wall).. It will be flagged and a drainage channel will be laid next to the house wall to take water away but wondered if I should treat the wall below? There is no damp now at all but wondered if it would be good practice.

See picture attached.

Many thanks for all advice.

There are rules on decking that relate to the original height of the land, I assume that a patio is also affected.

In any case, I would build a retaining wall away from the house wall, leaving a gap. You could design the gap to fit a readily available grille or duct.

I would like it to go up to the wall ideally.. It would look neater. Also, my father owns a couple of Tiger Cubs randomly

Do you have any ideas on the following:
Can you explain this proposed retaining wall - where exactly will it be located, and to what height?
Have you considered any affect the wall depth might have on the foundation of the lean-to?
Where will the channel drain to - how will it discharge.
At what ground depth will it be set?

The exposed brickwork looks plenty damp - and there are great damp patches showing in the upper left render.
All the render below the exposed brickwork must come off - in fact best practice would be to remove and re-do all that gable render.
The lean to is showing damp - some is green algae splashes from the gutter outlet & missing down pipe.

You need to locate the DPC's in both buildings.
fwiw: what looks like those Dutch scam dpc devices appear to be on the front elevation lower right.
Are you saying there's no indications of damp inside the property?

OP,
The above self sticking panels wont work with your proposals.
Neither will they work if a bit of broken masonry or a rock in the backfill pierces the skins, and allows moisture penetration.

Its designed for below ground and is very robust.

Clearly you have never used it, dont comment on things you know nothing about.

The infamous Dutch caps.

OP,
Its glaringly obvious why the panels wont work on your project - dont involve yourself with something that is expensive & unsuitable.
