Edward Bulmer 


Edward has spent 30 years in historic decoration, not generally working for heritage organisations; mainly for private owners and trusts. Nevertheless his work can invariably described as ‘historic decoration’ as these owners, like heritage organisations, aspire to historic integrity in the treatment of their buildings. The single biggest difference is that these houses are lived in and need to be fit for purpose in this sense. Edward’s career has been an exercise in delivering these two needs.

Edward Bulmer will be doing a study day at Syon House on Monday 18th September 2017.
