Mansion made with stone from medieval castle renovated and on sale for £1.5m

16th‑century Y Fan manor—partly built with stone from nearby Caerphilly Castle—is up for sale at £1.5m after a full restoration.
A London couple bought the damp, run‑down house in 2017 and, despite challenges like mould, mushrooms, 132 windows and very high ceilings, opened a seven‑room B&B in 2021.
They’re selling because hospitality is relentless and they want someone with more energy to take over—a neat “quit the rat race” renovation story.
