“Gary Butler was recommended to me by my neighbours, who correctly told me that he was exactly the right architect to sort out a problem I had with the local authority and my original architects and builders.  He had to take over the incomplete and incompetent restoration of a Grade II* listed terraced house in London.  This involved dealing with planning authorities, lawyers, neighbours and his desperate client, as well as making planning applications, finding new builders and overseeing the eventually wholly successful restoration, paying close attention to all details and always protecting the original fabric of the building.   Throughout the process he remained popular with the planning officials and the builders, and his interest in the house itself meant that he always worked cooperatively with the builders to find the correct and least intrusive solution to any problem.  His skill ranges from defining the correct reconstruction of an early 18th century roof to giving advice on suitable paint colours.  Gary and the team at Butler Hegarty were a delight to work with and in any future project I would not dream of employing any other architect.  I would recommend Butler Hegarty to any potential client, especially – but not only – if they had a project involving a listed building.”

Kate Gavron, private client

“Butler Hegarty Architects were committed to delivering a thorough Options Appraisal for the South Ealing Cemetery Chapels. They brought a range of expertise to the project, providing specialist guidance on conservation needs and approaches to repair, drawing on Gary’s particular knowledge of Victorian Architecture. Claire led on the community consultation aspects of the project, taking the time to identify and engage with people and groups in the locality to understand how the site could respond to their needs.  It was a pleasure to work with them and we appreciate the additional time they gave to support an Open House event at the Chapels.”
