The survey is carried out with a total station and, for a complex or old building, with a laser scanner. The precision of an area depends mainly on access to the premises, the regularity of the walls and the number of points measured: a furnished apartment or a room locked on the day of the survey means a measurement to be redone.
The time for our work depends on the number of levels and lots, and on the availability of the occupants. The check by the cadastre service and the creation of the titles by the land registry have their own timescales, which we do not control: we follow the file without promising a date.
We do not publish a flat rate (see our fees): the quote takes into account the built area, the number of lots, the state of the documents and any discrepancies with the permit.
The most common sticking point is not the measurement but compliance: a floor or an enclosed terrace built outside the permit must be settled with the municipality before any co-ownership procedure.
