Llanmihangel Place dates back to the 12th century; the first recorded building on the site was a one-storey structure which was owned by a Norman knight. During the 15th and 16th centuries, the site underwent a significant expansion which incorporated the original Norman structure into the basement. In the 16th and 17th centuries, the house was owned by the Thomas family, a prominent aristocrat family. The last of the family to own Llanmihangel was
Sir Robert Thomas, 2nd Baronet who lost a vast amount of the family's fortune. In 1685, Llanmihangel Place was sold to the Lord Mayor of London,
Humphrey Edwin. In 1988, it was bought for £139,000 by new owners who renovated the property. It was listed for sale in 2018 for £1.3 million. ==Layout==
