Newton House is situated in the 18th Century Dinefwr Park in Llandeilo, Carmarthenshire.  The house itself in the heart of the site was built in 1660, but now has a Victorian Gothic façade.

The works included a major internal and external refurbishment and alteration scheme to provide a new exhibition centre and tea-room to include all necessary lime mortar plastering, new joinery, oak floors and a major re-roofing programme of Welsh slate, leadwork parapets, chimney re-buildings and a comprehensive upgrade of the fire detection and security systems.
