Mosedale Gillatt Architects was appointed in 2017 at the commencement of the project and has acted as lead consultant since this time.

Following a rigorous analysis of site condition and priorities for repair, the visitor route and preferred location of new cafe, retail, interpretation and back of house facilties were established. This process involved significant consultation with both internal and external parties. Mosedale Gillatt approached the project in a highly organised way ensuring that all stakeholders ‘bought in’ to the process. 


'I am absolutely delighted to see the Hall and gardens being enjoyed by visitors and staff. The completed project is a credit to the Trust and its project team. With such projects it is never an individual but a collective of people who work positively together to produce exemplar results. This is the case with Seaton Delaval Hall.

To say that I am surprised by the transformation is not an accurate response. The seed for the project was planted a few years ago but the Trust had the foresight to ensure that the right architects and conservation contractors were involved. The care and attention to detail is extraordinary'
