Core Conservation – Windmill retrofit: waterproofing and insulation upgrade using Roman lime technology

This project converted a 200-year-old, 60ft-high, grade II-listed windmill into a combined living and home-office space, overcoming severe moisture ingress, curved walls and strict lime-only conservation requirements.
Using innovative Roman lime recipes, cocciopesto and aerogel-lime insulating plasters, the team achieved U-values below 0.5 while preserving heritage aesthetics.
Careful planning, collaboration with Venetian restoration experts and bespoke moisture-control strategies ensured the tower remained dry, warm and habitable.
