Challenge: A family in Rotterdam had a 1950s terraced house with a large brick chimney that was no longer in use. The chimney caused leaks during heavy rain and took up useful space in the attic. They were unsure whether a building permit was required.
Our approach: We checked the listed building status and zoning plan: not a listed building, not a protected townscape. Removing the chimney does not alter the main form of the building, so it is permit-free. We drew the complete demolition sequence for the flue on both floors and the watertight roof seal with zinc plates connecting to the existing roof tiles.
Result: Chimney completely removed, roof fully watertight, attic usable as storage. Drawing planned by arrangement; execution by a local contractor in 2 days. No permit procedure needed.
