Thematic Surveys

Thatch survey

All thatched buildings in Northern Ireland have been surveyed in detail. The results of the survey show that despite a massive loss of traditional roofs since the 1950s the surviving buildings display a wide range of the features which were once common across Northern Ireland. It highlights the importance of protecting those remaining thatched buildings which played a significant part in forming the character of Northern Ireland.

Pump survey

The surviving historic pumps of Northern Ireland have been researched and recorded in detail. As a result, several types were identified and the best examples of each protected.

Belfast roof truss survey

Belfast roof trusses are a form of roof support which was developed to utilise short lengths of timber. The trusses with their characteristic gently curved top member were often used for industrial buildings, but there has been a dramatic loss of these common features in recent years. With the help of the Joint Committee for Industrial Heritage, a thematic survey was carried out which identified all known examples. The best examples were surveyed in detail and several listed.

Mourne water scheme

The completion of Mourne Water Scheme was a key industrial project for the new region of Northern Ireland in the 1920s. Its completion was an engineering triumph and a source of pride. Features associated with the scheme, from great dams to small pumping stations, have been considered as part of a comprehensive survey and record. Many of the structures have now been listed.

Post war listings

In the 1970s, it was determined that only the most outstanding works of architecture after 1940 are to be deemed sufficiently special for protection by listing. Since the 1940s, building development significantly increased and international influences such as the Modern Movement became increasingly important. A thematic survey has looked at this period, which has informed subsequent decisions on the listing of more recent buildings.

Some buildings have not been thematically surveyed across Northern Ireland. In some cases, Historic Environment Division has agreed a joint policy with owners and/or custodians for their retention, as they may be of special architectural or historic interest.
