The Russian Orthodox Cathedral, London

The Grade II listed building now known as the Russian Orthodox Cathedral was formally the Anglican Parish Church of All Saints. The original building was designed by Lewis Vulliamy and built in 1849, it was then later remodelled by Harrison Townsend in 1892. The significant interior decoration, including sgraffito, mosaic and stained glass windows, were added between 1896-1903 by Heywood Sumner, a leading figure in the international Arts & Crafts Movement. 

Conservation work was undertaken to the sgraffito murals and apse mosaic as a member of the Hare & Humphrey's team. Treatment included the extensive cleaning of the smoke blackened surface and consolidation of loose and friable material. Further conservation was also carried out to the stained glass windows and painted faux marble decoration.
