Hi,

Is this normal for a row below the DPC line?

Do you mean the damp appearance?

If so then it's fine. The garage floor is below DPC, by design, so that a fuel spill won't run into the house.

If you ever converted it into a room you add a DPM lapped up the wall and raise it up with insulation and flooring within the membrane.
 
Thanks.

My neighbour has built right upto the dpc line with no drain so was concerned.
 
Ah OK, you think they've raised the groundwater level. Impossible to tell, but I do see similar effects on our garage wall that adjoins the house, and also on the outside walls below the DPC. It's pretty normal for bricks to wick water upwards. How does it compare with your external house walls below the DPC?

Have they built the ground right up to the DPC? If so you really should have a polite word. They won't know it's a problem but it is - they should be a couple of bricks below it ideally. But this is the issue with having an outside wall in someone else's garden. My in-laws have soil and climbing plants all over their neighbour's wall.

It would matter less on your house walls with a cavity, but your garage wall is probably a double thickness wall without a cavity.
 
The owner had patio laid to about 30cm then had concrete in the gap (push push push all the time).

They just had decking installed over the patio and concrete with a pergola with slanted roof directly running off towards the wall with no gutter.

No cavity in there.
 
The set back and back-to-front air brick is not normal
I guess it's one of two, back-to-back, with the outer one flush with the outer face.

Your neighbours are not being neighbourly. We had a similar situation with our neighbour's decking, thankfully just tipping into our garden rather than garage so just merely annoying. Our solution was to move to the countryside, away from the awful human race.

That wall will be getting a lot of water when it rains. Tell them you're getting damp in the garage, see what happens. A shrug probably.

Ensure your next house is fully contained within its own boundary.
