Historic Decoration was founded in 2016 by interior designer and consultant Caroline Percy and architectural historian Oliver Gerrish. Our series of study days at Syon House, Salons at Brunswick House, four day course and tours aim to explain and define the many and varied aspects of the history of British interior design and to explore the options available to assist in the restoration and reinterpretation of historic interiors today.

Our speakers are all established experts in their respective fields and they vividly describe the evolution of interiors through the centuries and suggest how this knowledge could be applied when decorating a period home in the context of the 21st century.

For the amateur as well as the professional, for the owners of historic properties and those involved in their restoration and redecoration, Historic Decoration provides a forum to offer practical advice.


Sentimental Jewels at Syon Park

16th July 2019

Historic Decoration has teamed-up with Fellows to look at a key aspect of historic decoration - jewellery, as a way of decorating one’s person, as well as its role in historic portraiture.

Join Historic Decoration and Fellows Auctioneers at Syon House. Set amid rolling parkland, Robert Adam’s Syon House is one of the last great country houses in Greater London.

Sentimental Jewels will be a fascinating day with access to the house and its history. A talk from Art of Mourning’s captivating Hayden Peters will explore the sentimentality of jewellery over the last 500 years and the hidden meaning behind certain objects. 

After a break for lunch, you will tour the magnificent house, led by interior designer Caroline Percy and architectural historian Oliver Gerrish from Historic Decoration.

You will have a chance to relax over tea in the beautiful Green Drawing room with our hosts and speakers. Fellows will be providing some gorgeous period jewellery for you to try on in the context of this great house.




The Evolution of Historic Interiors from Renaissance to Regency

30TH September - 3rd october 2019


This four-day course provides a foundation for the analysis and interpretation of British interior design from the Renaissance to the Regency. 
Chronologically organised, visits to historic buildings will highlight the key interiors, architects, designers and movements which demonstrate how the historic house has evolved over the centuries from the reigns of Henry VIII to George IV. 
The tours of historic buildings will be accompanied by in-house experts. 

We explore the decorative devices employed by great designers and architects from the past and discuss their relevance to interior design in the 21st century. 

The interior designer, Caroline Percy, and architectural historian, Oliver Gerrish, will lead the course, assisted by Catherine Fellowes. We will be based at Hotspur House, Caroline's home which is close to Robert Adam's Syon Park.
