  • The care and repair of historic timber frames and roof structures
  • The range of historic roof coverings
  • Problems of decay and methods of repair


The venue has been carefully chosen as the museum has a varied and extremely fine collection of rescued buildings dating from the medieval period through to the 20th century. The buildings illustrate a wide range of structures and roof coverings and building materials used at the various periods. The day will include formal Power Point presentations, material handling sessions and first hand observations of the buildings. The mornings presentations will be based in one of the barns and the afternoon will be spent looking at a wide range of buildings on site so come suitably dressed for the weather conditions of the day.

The Museum

The museum was founded in 1976 with the aim to rescue and restore common buildings typical of the Chilterns area, which otherwise would have been destroyed or demolished. The collections also contain artefacts and equipment associated with the buildings and local crafts and rural industries. The museum is in 45 acres of parkland and woodland and contains 35 buildings rescued from destruction and moved to the museum site. They include medieval barns and later agricultural buildings, domestic buildings of various periods including a 20th century prefab and rural industrial/craft buildings. The process of dismantling and rebuilding structures has enabled a better understanding of historic constructional techniques and the use of traditional materials. It has also enabled the developing and testing of conservation approaches and methods which are now becoming applicable to commercial renovations of our stock of heritage buildings.
