The flagship Curtain Rises project signified the first major capital works since the National Trust acquired the property in 2009.

The landscape design included interpretation and play facilities including features based on historical layouts and data. Todd Milburn delivered Quantity Surveying services, ensuring the financial aspects of the scheme were kept up to date at all stages from the initial survey and schedule of repairs, through to the final account. The scheme has received local and national recognition, being awarded the winner of the Conservation and Regeneration category of the Constructing Excellence North East Awards 2021 and in 2022 it was crowned Heritage Project of the Year in the UK RICS Awards.
