Rugged Cornish coastline and historic ruin

We don't fix old buildings.
We listen to them.

Master craftsmen dedicated to the ancient masonry, breathing walls, and enduring spirit of Cornwall’s pre-1919 stone properties.

The Art of Preservation

There is a quiet dignity in a wall that has stood for three hundred years. Our work is not about forcing modern solutions onto ancient stone; it’s about understanding the alchemy of hot lime, the precise bedding of Killas, and the rhythm of the Cornish weather. We restore history by honoring the hands that built it.

Modern cement strangles an old building, forcing moisture inward. We use traditional hot mixed limes and mature putties—the only way to let ancient masonry truly breathe and dry naturally after an Atlantic storm.

Scantle & Delabole

The lost art of the Cornish scantle roof. We bed traditional Delabole slates in a rich lime 'porridge', hanging them on hand-cleft oak pegs, just as the master roofers did centuries before nails existed.

Killas & Granite

Cornwall is built from the earth it sits upon. We source, read, and lay stratified Killas and dense igneous Granite, ensuring structural and chemical compatibility that lasts generations.
