Louisa from RDA delivered successful lecture and guided walk for IHBC West Midlands this month.

“Louisa Davidson’s talk and walking tour in the morning was fascinating and gave insight into the eclectic and marvellous architectural heritage of Great Malvern.   It also highlighted some of the shocking things that can happen when development is not considered holistically with regard to every aspect of the historic environment, designated and non-designated heritage assets including setting and significance and the impact that new development can have, if not checked by current planning policies and informed thinking.  It certainly provoked a lot of discussion for the delegates attending.”


Jacob Rock from RDA was selected to take part in this year’s SPAB working party, he jumped at the opportunity to develop his existing skills and work with new approaches to traditional materials and processes in hot lime pointing, and in soft capping.
