Bit of background: We stay in a semi-detached with up and downstairs. We had a doorway knocked into an outside supporting wall so we could access an already in place extension. It was more convenient with this layout. We submitted plans for the work but for the life of me I can't find them and the building clerk is coming next week to inspect it (hopefully grant a certificate) The work was carried out 2 years ago so its all very hazy the actual details.
What I'm looking to know is, is there a guide on how much the concrete lintel should overhang the brickwork below? Given it is the ground floor of the outside wall. They told me just to take pictures at the time as that should suffice.
Cheers.
