Hi, I want to widen a doorway in a non-load bearing wall from a 500mm opening (small I know) to approx. 2000mm. The current lintel is wooden, so therefore need replacing with (I assume) a concrete one.
Firstly, what size do you think I need (wall is single brick and plaster with 3 courses of brick above lintel) and, Secondly, do I need planning permission (or what building regs do I need to follow)?
