Lucy joined Donald Insall Associates in 2006, bringing a passion for designing new interventions within heritage buildings and settings. Her work for the practice has included the repair and reuse of a number of redundant or underused private country houses so as to ensure their continued survival and use. Lucy regularly undertakes the role of consultant to residential and commercial building owners on issues of planning policy which involve heritage assets. Many of the projects on which Lucy has worked have also involved difficult programming and contract management expertise. Lucy has also undertaken a number of detailed studies of heritage fabric, piecing together long-lost or destroyed fabric.
