Farm house built circa 1860. Rot to suspended timber floor. The timber wall plate to the sleeper wall along the front external wall had completely disintegrated despite being wrapped in plastic sheet to isolate it from the damp masonry. No concrete ‘oversite’ under the floor as was custom at that time (just bare earth). All of the adjacent rooms have solid concrete floors so no through ventilation in this area. The retrofit air bricks on the front external wall provide little air flow due to the way they have been installed. Missing/loose pointing on the external wall and defective rainwater goods to roof above. This is resulting in rainwater penetration and heavy dampness at the base of the wall. Range of issues here that need to be resolved to deal with this properly and provide a solution that works long-term.
