Only single layer of brick and plasterboard.
Been up number of years and now the single level extension with a flat roof is cracking (through/around) the bricks.
Should I use a concrete lintel with metal in it, more than 1, or a metal lintel or a RSJ cut down?
Should I opt for Thermalite or 4x2 timber (the 2nd skin would be on the inside).
Cheers
