As part of an intermunicipal project, the Administration Union Wilgartswiesen-Hauenstein developed around 66.500 m² of usable commercial space on 11,2 ha of topographically very uneven terrain.

The company igr d.o.o., headquartered in Zagreb, recorded positive business growth as defined by the company's Management Board in the development plan.

Abo Wind AG, Wiesbaden, is building an approximately 5 ha area with greenfield solar power plants in the Odenwald in the municipality of Mossautal.

igr was invited to a expert discussion on the subject of heavy rain management in municipal experience, which was organized by the "Grünen" parliamentary group in the Bavarian parliament.

On October 28th, 2021, igr AE was officially commissioned as part of a consortium by the Hamburg Investment and Development Bank (IFB Hamburg) with the project: "UAM Vertiports - Design & Development of a modular Vertiport".
