Interviewer instructions
3.3.3 Question 4 - Year in which construction was completed: this information is important. You should do your best to question the owner in order to find out this information; also, persons who have been living in the house, the neighborhood, or the town for a long time (can supply this information). Many buildings, especially in towns, have the building completion date engraved or painted on the facade of the building.
For the first 4 categories, it is often enough to find out the building completion date to within a few years to be able to answer correctly. Lacking direct information, you can sometimes classify buildings by comparing them to others which are typical of that time period. For example, in some towns entire sections are from the 17th or 18th century and easily recognizable. The town hall may be able to let you know if there are large groups or blocks of buildings built at well- determined time periods.
For buildings built since 1948 (box 5) you should make a special effort to specify the completion date.
