Our clients include museums, libraries and galleries in the United Kingdom, Europe, North America, South America, Canada and Scandinavia as well as Government institutions. 

The Gallery has also undertaken professional appraisals for trustees, legal firms and estate managers acting for Historic and Country House owners with architectural and heritage collections.  The Directors have many years of experience as brokers of Private Treaty Sales for independent owners of private collections. 

Architectural practices at home and abroad, as well as individual architects and their families, have also required appraisals of their archives and the Gallery have assisted them in finding an appropriate home for such collections by way of an appraisal and negotiation of a private treaty sale on their behalf.
