As a result of four days work the walls of this 500 year old house in Brittany have been built up to a level that will support roofing trusses. The back (north) wall had been capped in the past and required no work. The side (east) wall had been home to a tree and well established ivy. This has mostly been removed and some remedial work was needed to level and cap the top of the wall. The north-east corner was stabilised with mortar and stone. The front (south) wall had suffered most and required the removal of loose masonry. Three upper floor windows needed new wooden internal lintels which were formed from timber 80/100mm thick depending on the span. Using a laser level, a string line was erected and stonework was built up to the level on the inside and outside faces. This stone was held by cement mortar which, once set, allowed the cavity to be filled with loose stone and more mortar was then poured on top. This was then levelled to form a cap. It is estimated that some 5 tonnes of material was needed to complete the job.
