A trend has been identified for historic buildings that have been inspected three times or more. In 70.3% of buildings inspected on multiple occasions the condition of the structure has remained the same, in 21.2% it has improved and in 8.6% it has deteriorated. The structure of ‘road and water infrastructure’ and ‘defence works’ deteriorated less than in the other categories.
The diagrams above show the proportion of historic buildings inspected on multiple occasions whose structure has improved, deteriorated or remained the same. The diagrams show the distribution for all historic buildings inspected in the categories ‘good’, ‘reasonable’, ‘substandard’ and ‘poor’ and the distribution by CBS category.
A trend was identified only for historic buildings on which data from at least two inspections are available (n = 10,579). Buildings that were inspected only twice in successive years were disregarded.
Condition of structure remained stable in 70.3%
In an average of 70.3% of inspected historic buildings the overall trend was for the condition of the structure to remain stable. In 21.1% of listed buildings inspected on multiple occasions between 2008 and 2013 the condition of the structure improved, and in 8.6% it deteriorated.
Trend by score category
In 84.4% of listed historic buildings where the condition of the structure was judged to be poor in the first inspection, the condition improved. 1.8% of those found to be ‘substandard’ had deteriorated by the last inspection, and 71.2% had improved. Where the condition was first judged to be reasonable, 3.9% had deteriorated and 51.1% had improved; where the first inspection found the structure to be ‘good’, 91.4% remained the same.
Trend by cbs- category
Among the various CBS categories, it is noticeable that three times as many historic buildings were found to have improved on the last inspection as were found to have deteriorated. The only exceptions were ‘defence works’ and ‘road and water infrastructure’, where the ratio was 1.5 : 1. The category ‘parts of residential properties’ is also anomalous. Not a single object in this category was judged to have deteriorated, and 36.4% had improved.
National Monuments and Historic Buildings Inspectorate (Monumentenwacht Nederland) – inspection reports 2008-2013
Monitoring frequency: annual
The trend shows the difference between the first and most recent inspection of the structure, and indicates whether the condition of the structure improved, deteriorated or remained the same over the period in question.
The trend was identified only on the basis of listed buildings that had been inspected at least twice (n = 10,579). Buildings that were inspected only twice in successive years were disregarded.
