Tredegar House

We were commissioned by the National Trust to carry out an extensive historic building recording and heritage assessment at the Tredegar Estate in Newport. 

The work provided a detailed record of the Grade I Listed Stable and Orangery and the Grade II Listed Greater and Lesser Barns, the Mill and Clore, and the former estate Steward’s cottage, Bryans Building. The project produced a document to support planning, future conservation, management, and redevelopment of the buildings and wider site.


The Tredegar Estate was home to the influential Morgan family from the 15th century to the mid-20th century. Around 1670, the Tudor house was expanded into a grand courtyard-plan building with classical brick elevations. The surrounding estate was redeveloped, including a substantial Stable Block, designed to complement the house and reflect the Morgan family’s wealth and status.


Recording followed Historic England Level 3 and 4 guidelines and included photographic surveys, drawn records of roof structures and joinery, annotated architectural drawings, and laser scanning to provide accurate plans, elevations, and cross-sections. The survey identified multiple phases of alterations, including roof changes and internal remodelling. The Stable Block and Orangery were assessed as of very high heritage significance, contributing to the group value with Tredegar House and courtyards.


We considered ways to enhance the estate’s heritage significance, including restoration of decorative schemes and a mechanical clock and bell. Improving access and interpretation of the rooms was highlighted to enhance visitor understanding of social and working life. The ancillary buildings retained much of their historic character, showing evidence of phased alterations linked to the estate’s changing fortunes. We produced a comprehensive illustrated report detailing the historic background, building descriptions, phases of development, and a heritage assessment with conservation priorities and objectives.
