The IBA is a set of organised exceptional circumstances. From 2012 until 2023, the whole of Thuringia will be a laboratory for the future. The International Building Exhibition (IBA) in Thüringen aims to be an agent of change, fostering partners willing to explore new directions and supporting those implementing model projects. The mid-term exhibition was the opportunity for a public résumé of the interim results of the IBA, and coincided with the centenary of the founding of the Bauhaus. The IBA interim presentation ‘StadtLand’ was held at the Eiermannbau from 24 May to 29 September 2019.
