hi all,
In preparation for a loft conversion I've found that the walls supporting the purlin mid span are no longer sound.
The purlin has moved downward slightly (almost as if the roof has spread and sagged) and cracked the pillar wall that supports it, pushed bricks out of place etc.
I'm going to support the purlin on acros, remove the wall then rebuild using 7n blocks etc.
My question is, should I try to raise the purlin into its original position or simply take the weight and then build to its current resting place?
The difference is only a few cm. It's been in its current position for three years and has moved a minimal amount in that time.
