I have had an offer accepted on a house. My buildingsurvey highlighted the following as condition rating 3 -
"The purlins were not designed to take the weight of the interlocking concrete tiles and this has caused some bowing to the purlins and rafters. You should ask a suitably qualified person to inspect and provide you with recommendations. Condition Rating 3. Further investigation required.
The attic conversion does not meet Building Regulations. For example, there are no
escape windows, there is no interlinked fire detection on each floor, the doors do not have self closers allowing access to a smoke free corridor in the event of a fire and the door to the attic opens onto the stair/ hallway.
There are signs of woodworm/ wood rot in the small hole over the bathroom ceiling. You should ahem some access panels fitted both here and to the main attic, so that the timbers can be inspected. The laths in the ceilings are prone to damage."
My question is - can purlins be added/reinforced from the inside, or is it a roof off job? I would also like the insulation investigated up there, when I viewed it last week it was like an oven!
