Hi,
Am having a conservatory built and now that the builder has built the foundation I noticed that one of the air bricks is in line with where the inner leaf of the new wall will go. So question is how to extend this vent out to the other end of the new wall? Surely the extension pipes can't run under the wall. Been reading on the forums but can't find any advice about this issue. Most topics are about running vent under the new floor since they are on the inside of the new conservatory. Attaching picture to clarify the issue. Hope someone has come up with this situation before and has a solution that would be compliant to building regs.
Thanks
