Life on the house facade

Would you like to fill the façade of your building with bustling life? That’s a great idea, as façades as habitat structures play an important role in promoting nature in cities. As “artificial rocks", they can provide unique breeding places and habitats for different types of birds and bats. Sparrows, house martins, common swifts, kestrels or several types of bats are all synanthropic animals, and thus depend on our buildings as habitats in cities.

Another possibility is façade greening. This brings vertical green and flowered areas into the city, which leads to a more enjoyable micro-climate while creating important habitats.

Target species

Common Ivy

Common swift

House Martin

Italian woodbine

Kuhl’s pipistrelle

Good to know

  • Existing breeding places of birds or bat roosts should be maintained when starting construction.
  • By opening existing hollow spaces or by mounting nesting boxes or bat roosts, additional structures can be created.
  • Façade greenings act as local "natural air conditionings” and are subsidised by the City of Vienna.
  • Starting renovation measures on buildings at the wrong time of year may lead to great damage among the bats and bird that nest on buildings.

What does the City of Vienna do?

The City of Vienna - Environmental Protection department subsidises façade greening up to a maximum of 5,000 euros. You can apply for funding here:

For a while now, Vienna has focused on promoting animals living on buildings. You can find more information on house martins, common swifts, bats etc. here:

Facade greening as flowered areas

Vivid facade greening beautifully embeds the building into its surroundings. Our feathered friends will enjoy it too. Behind the dense shoots and growths can be many a bird’s nest. As not every climbing plant is suitable for every façade, and not every lattice is suitable for every climbing plant, it is advisable to consult experts on the matter. This pre-emptively eliminates potential risks, and nothing will stand in the way of the embellishment of the building.

Habitats for animals that nest on buildings and how to promote bats

For centuries, birds and bats have been living close to or even under same roof with us. We enjoy their chirps and twitters and admire their daring flight manoeuvres through the urban canyons. This is urban nature at our fingertips. Together, we can make sure it stays this way.
