Pocket park no. 1: Zollhausdach

by IG Wilde Biene | Sep 15, 2026

The construction of the Zollhaus in Zurich destroyed a unique wild bee habitat that had been part of the railway yard of the main station area. The City of Zurich did not require the developer to provide any compensatory measures for the rare and endangered wild bee species living there. On the roof of the Zollhaus we therefore want to make up for part of that loss of habitat: the roof is used only on some of its surface, while other parts are given over to wild bees.

Please note: The Zollhaus roof on Langstrasse is not a «real» pocket park, as it is not public, freely accessible space. Visits are possible only by arrangement with either the IG Wilde Biene or the Dachdiversität association, or as part of a guided tour. If you are interested in a guided tour, please get in touch.

Partners
The upkeep of the Zurich pocket parks is made possible by Daniel Labhart from Schafisheim in the canton of Aargau. This innovative horticultural entrepreneur has a genuine commitment to biodiversity and supports the work of IG Wilde Biene through the sale of his planting bricks optimised for wild bees.
Petrig AG in Volketswil supports us with custom-made, weatherproof mounts for the information panels of at least the first 20 pocket parks.
And Grün Stadt Zürich lets us use the city's small parks rent-free and bears the cost of the improvement measures.
