The reed-lath vault is a traditional lightweight construction system, made of reeds fixed to a timber support structure and finished with lime-based plaster. Its lightness is one of its main qualities, but it also requires very careful intervention when local damage, detachment or degradation occurs. The on-site inspections highlighted critical areas of the historic ceiling, including localized cracks, loss of plaster, and detached portions of the reed-lath system. The objective of the intervention was not to introduce an invasive rigid solution, but to preserve the original construction logic while improving safety and local stability. The design process combined direct survey, damage assessment, structural modelling and detailed construction drawings. The numerical mod
