Originally planned by the state capital Hannover, Auf der Horst became an important factor for the independent urban development of Garbsen in the following years.

In the first decades of the post-war period, Garbsen was primarily a classic commuter town for numerous workers in Hanover's industrial enterprises such as VW Nutzfahrzeuge, Continental or VARTA, today Johnson Controls.[which?]

By the winter semester 2019/2020, the entire Faculty of Mechanical Engineering is to be united on the Garbsen campus, which is currently under construction.

[needs update] Garbsen belongs to the Weser-Aller-Flachland natural area and is situated between the lowlands of the river Leine and the Otternhagener Moor.

Thus Garbsen's hills disappeared, and today only street names remind us of them (among them Osterberg, Mühlenberg, Streitberg, Pottberg).
