The day’s course will consider in depth three aspects of building conservation.
- The History and Architectural Development of Stone Structures
- Care and Repair of Historic Stonework
- The History of Brickmaking and Building in Brick
- Interpreting Historic Brickwork
- Care and Repair of Historic Masonry structures and Selection of Mortars
The venue has been carefully chosen as it represents a fine example of Medieval and later stonework. This major and very impressive medieval castle was extensively reconstructed in the mid to late 14th century. In the 17th century the domestic range of the castle was in poor condition and was remodelled with all the comforts of a country house. It was further updated in the 18th century including the addition of a prestigious coach house in the grounds where we are holding the course. In 1871 fire extensively damaged the great hall and it was reconstructed to a Victorian taste. The buildings display masonry of many periods and centuries of repair including 20th century work. The day will include formal Power Point presentations, material handling sessions and first hand observations of some of the buildings.

This includes the development of historic building technology, traditional materials and hands-on craft training. Work for Local Government Authorities includes Conservation Area appraisals, historic building condition surveys and feasibility studies. He has provided training exercises with local communities to raise awareness of their village plans and local heritage interpretation documents and he has provided Traditional Skills Awareness Courses for a number of bodies.
He undertakes the Historic Analysis of buildings and produces: Statements of Significance; Method Statements; Impact Assessments and Specifications for the repair and conservation of traditional buildings.
He lectures for various CPD providers, Universities and national building conservation organizations including SPAB, RICS and the Weald and Downland Museum. Topics include: Bricks and Mortar; Lime, Plasters and Renders; Cob and Earth, Timber Frame and Stone Structures and Traditional Roofing.
The day will include formal Power Point presentations, material handling sessions and first hand observations of the building.
The History and Architectural Development of Stone Structures
Bricks have been a principal building material in many parts of the country since the 16th century. The history and development of brick buildings and brickmaking will be examined up to the middle of the 20th century when bricks ceased to be a mainly local vernacular material and became a mass produced product by a few large international companies.
A selection of different types of bricks from different sources and periods will be handled and discussed, paying particular attention to how they were made and fired and how this affected their durability and character. Looking closely at historic brickwork can give clues as to how the bricks were manufactured and laid and what alterations the building has gone through since its original construction. This process can be likened to reading a detective story: the clues are there, they just need interpreting by the observer, thus enabling a correct and aesthetically pleasing repair/restoration to be achieved.
The first important stage of this process is to identify the sources which have caused the problems of decay to occur; these must be resolved before the stonework or brickwork can be repaired. It is also important to understand the nature and function of historic mortars and the dangers of the use of modern cementitious products. The use of inappropriate mortars can result in the rapid deterioration of historic masonry and long term structural problems. The problems of water movement, salts, frost and the cleaning of stone and brickwork a will be examined. The methods of re-pointing will also be considered, not only for aesthetic reasons, but to ensure the correct performance and durability of the new joint.
