The practice has a worldwide reputation for our work in the care and conservation of historic interiors, especially in the conservation, restoration and reproduction of traditional wallpapers and painted schemes.

The practice was established in 1980. Since then, we have been involved in many important restoration projects which have won widespread acclaim.

Allyson serves on the Board of Trustees of The United Kingdom Institute of Conservation and is Chair of the Historic Interiors Group. She lectures extensively on wallpaper and the conservation of the historic interior and has written many articles on the subject. She is a past advisor to Sotheby's
and The National Trust and has undertaken research into the use of Chinese Papers in the English Country House as part of the V & A / RCA Conservation Programme.

Allyson and her team operate throughout the UK for architects, contractors and private individuals, as well as high profile organisations like Historic Royal Palaces, English Heritage, The National Trust and Historic Scotland. She has also worked on conservation projects elsewhere in Europe, the USA, Australia and Africa.
