City Hall at the Spui to get green roof
The City Hall at the Spui is set to undergo a major renovation. A total of 5,200 m² of green roofing will be installed on the City Hall, the Central Library, and the Forum building. Work has already begun, and the new green roof is expected to be completed by May 2026.
After more than 30 years, the roof of the City Hall needs to be replaced. The municipality is using this opportunity to also make the building greener and more sustainable. This is better for the climate. The new green roof will therefore include:
- additional insulation
- rainwater storage
- solar panels
More green roofs in The Hague
The green roof helps reduce heat stress (excessive heat) in the city centre. The greenery cools the building, making the surrounding area less warm. The roof also captures rainwater and slowly releases it, reducing pressure on the sewer system during heavy rainfall. The municipality hopes the green roofs will inspire residents of The Hague. There is still much more potential for green roofs in the city. Visit denhaag.nl/daken to find out what you can do. Be inspired by the city’s residents.
Urban nature on the roof
A special piece of urban nature will be created on the roof between the City Hall and the Forum building. In addition to plants, there will be a feeding tray, water dish, sand tray, and an insect hotel. These features will promote biodiversity, supporting a greater variety of plants and animals. The roof with urban nature will be clearly visible from both buildings, allowing visitors and employees to enjoy the natural surroundings.
