William Madocks designed the house and grounds at Tan-yr-Allt in the early-19th century as his own home. The house, which is now a country house hotel, is set on a steep slope with good views. The grounds incorporated a small park and oak woodland, which Madocks managed as part of the design. There is a well-preserved kitchen garden.
