As part of the Casa de Cowboy rebuild (which I think should really be called the Palacio de Cowboy because Casa doesn't really convey the full scope of the stuff we're finding), we're extending the house a bit as per the photo below. This used to be a brick patio that went up to the side of the house, you can see the remains on the left.

 

 

 

 

We'd like to reinstate the patio, which soaks up the sun and radiates the warmth back well into the evening, however for waterproofing purposes the fibrolite cladding has to be brought down to the level of the yellow lines in the picture. This means that it's below ground level, or at least below patio level, and we can't bring the patio right up against the cladding.

 

 

Does anyone have any ideas on how we can restore as much of the patio as possible? The builder is looking into how close we can go to the house wall in a code-compliant manner, but it seems a bit vague. And we definitely want the warm brick patio back, not a narrow deck or something similar.

If you were doing a deck the stringer is allowed to be bolted to the wall with 12mm packers holding it off the surface to allow drainage. So any solution that gave at least that much clearance could be OK. If you had to retain the patio level the blocks closest to house could be supported on a horizontal H5 capping the top of the wall.

A deck is different to a patio. Strip drain by house may be a solution to allow patio to be put back. It's all about stopping moisture running off patio on to cladding. If no drain then patio needs to be a certain distance below cladding. So I'd look into drain options, it's what I need on new housing when they have concrete patios level with cladding or anywhere near it.

There's going to be a drain running along the side of the house next to/just below the cladding, the question is how close can the patio get to that. In other words can you have patio, drain, cladding or do you need more separation than that?

The other problem with the drain is that it'll be well below the level of the patio since it's below the level of the cladding, so can you have a very deep drain, or perhaps a grille well above the top of the drain? I'll post a diagram when I get home tonight.
