We visited the regional archive Eemland to have a look at the drawings and building dossier of our house. This to amongst other things determine what the carrying capacity of our roofs is. The city government keeps these records of all buildings, from the first drawings for the building permit application, right up to the finished house.
The house was build in 2004, and those drawings havent’ been digitised yet. The archive’s staff told me there is an effort to do that going on, and likely they will have digitised it all by the summer of 2020.
