With a lintel?

Will this be a normal door / window type lintel ?

set 2 7N blocks in the wall (1 each side), with the tops about 1 inch above the pipe (distance is not critical). Use a standard concrete lintel to span the top.

If there is some reason to suspect the load is not just simple walls and stuff, you will need an engineer to caculate the lintel. But given the span will be about 6 inches, it should hold up many many times the weight of the wall.

Assuming this is a new build.

It depends how wide the pipe is, but generally up to 230mm diameter you could just shutter around it and leave a 50mm space all around (for any settlement) and then pour the concrete. More than this size pipe, and do the shuttering , but throw a couple of re-bars or a small rsj/angle iron into the concrete just above the pipe

For brickwork, just do the same, but with brick and a concrete lintol with min 100mm bearing past the 50mm gap.

This problem was on one of those garden makeover shows a while ago.

Trouble is, I can't remember what they did.....................................

standard lintel cut to about 15" IIRC.

leave a bit of a gap around the pipe, and backfill with peashingle.
