No stupid question. The construct "property made up of several parcels" only occurs in reality and in the purchase contract. In the land register and the cadastre, an uncombined property has a separate number and its own land register sheet for each parcel involved. However, this case is becoming increasingly rare because it practically only occurs in old village areas where no land reallocation had yet been carried out for the development. Nowadays, the long narrow fields or gardens are regularly subdivided into compact building plots in parallel with the development plan procedure.
Thanks! I was actually quite confused as to whether I had somehow completely missed something all these past years.
But then another question regarding this, since it specifically concerns the floor space index: how is it handled then? If someone only owns 2 parcels as in this case, you can simply add them up if necessary and consider them as one property for the calculation. But how would it behave if someone owns, at the edge of town next to their house—which stands on several parcels—also parcels/one parcel where, for example, a large garden shed or an access road etc. is to be built, because they are used as part of the property and are also allowed to be built on... what then applies to the calculation? Are the parcels involved taken together or is the respective surface sealing calculated individually for each parcel or how does that work? The property in this case is not surveyed as a whole, but only the individual parcels.
