Zone
2-geschossige Wohnzone - dicht

New builds: federal building and dwelling register. Zones and storeys: estimate from the zoning plan and building heights. Whether and when anything is built is up to the owners.

What the neighbourhood will look like

What stands on the plots today is hidden; 35 planned buildings are shown as volumes.

No dates: the building register has no completion dates. «When everything is built» shows all registered projects together – not when they will be finished.

Simplified volumes from the building register (footprint, number of storeys, 3 m per storey), aligned to the parcel – not the architecture. Existing buildings on these parcels are hidden.
