You can have the validity of your building permit or partial permit extended if you have not started your construction project within three years of the permit being granted or if construction work has been interrupted for more than three years.

This extension is important so that you can continue to use the permit you have already been granted without having to submit a new application. The extension of the period of validity is relevant for you if you were unable to implement your construction project within the originally planned period due to delays or interruptions.
