In 1999 Palatia Ingenieur- und Städtebau GmbH, a subsidiary of igr, opened a building area in Rockenhausen, district Dörnbach. Due to the high demand for building land, the previously unrealized areas were also developed by the Palatia in 2020. 

19 additional building sites were created on an area of 12.000 m². Planning and construction supervision were carried out by igr. After four months of construction, the builders could start house construction in November 2020. All building sites have now been sold and over half of the residential buildings are under construction.
