Dining room ceiling.
After part of our dining room ceiling collapsed, we decided to seize the opportunity and insulate the ceiling and therefore the bedroom floor above it. We got to see the amazing wattle and daube of its 16thC construction (twigs, horse hair and clay, and beautiful old beams beneath), but decided to rebuild with modern materials (fibre glass and Sheetrock). We are also replacing the beautiful but dangerous old wiring, while we are in there.
