We have indicated that once the Einstein Telescope is built, little of the underground observatory will be visible in the immediate area. While most of the people who will soon work for the telescope will do so in the Euroregion, they will not do so in and around the observatory itself. For example, a research centre is more likely to be set up in one of the larger, surrounding cities. Housing will often focus on those cities. In addition, the spatial layout and housing supply also differs in the border region between the three countries. The housing market will obviously be monitored towards 2035, and there is still plenty of room to manage this.
