    Hi all, long time guest user but first post here.

    We are currently having a single storey extension built. There are various private and public sewers that run under the extension with a man hole having been removed. The next obstacle is bridging this pipework for the foundations, because of how the waste exits our property and the neighbouring property a support can't be built for a lintel.

    The next thing to look at would be attaching the lintel to the existing foundations, my question is what would be a compliant way of supporting the lintel? Does anyone have a suggestion that could be presented to building control as they don't want to provide guidance beyond yes/no answers.

    The wall comes out perpendicular from the existing building and runs along the boundary (patio/outbuilding) all of the pipes in the image need bridging but the real issue is regarding the two soil pipes that come from our property and the neighbours property and run along the line of the wall before joining/turning towards the inspection chamber.

    Because of the line that the pipes run initially a support can't be built to take the lintels at the right hand side, how could the lintel be supported on the existing property? Is there a bracket that could be used? Does it mean trying to recess the lintels into the existing footings?

    Did anyone draw up plans who can do their job properly?

    It does not seem like you will be able to put a foundation under all those pipes, so you may be looking at a beam in the ground where that red line is, and maybe a suspended floor. Or an engineered suspended reinforced slab.
