Design your construction gap with Allplan

Our cities are becoming more and more crowded. Often, redensification is the only remaining option for creating urgently needed living space. We want to challenge your creativity and encourage you to fill an imaginary construction gap. You want to put a 5-storey car wash in the gap? Sure! Or a stylish residential high-rise? Go for it! 😊


  • The boundaries of the property and the surrounding buildings form the framework.

  • In the 25m x 5.7m building gap, you may plan 30 meters in height and 15 meters below ground, both from the top edge of the terrain.

  • Submissions will be evaluated based on buildability, appearance, and utilization of the given space.

  • We have already created a vacant lot as a model in Allplan.



Model - Perspective


  • The contest will begin on May 2, 2022 and end on June 19, 2022.

  • A selection of the best submissions will be published on our social media channels from June 27th.

  • Our internal jury of experts will select the winners. The announcement will be made on July 1st.
