Dyrham Park is a large Grade I listed mansion near Bath owned by the National trust. The house was built to the designs of the architects Samuel Hauduroy and William Talman between 1690 and 1702 for the charismatic owner, William Blathwayt.

​

DHV Architects were appointed by the National Trust to develop the Growing Dyrham masterplan project for the entire site to RIBA Stage 2, as part of the National Trust's Transformation Programme. The project aim was to enhance all the visitor infrastructure and facilities at the mansion hub and across the site to cope with growing visitor numbers.
