Extension building Sonne 2.0

Ten years of successful and economic activity, countless enthusiastic guests and the still growing demand in all areas formed the foundation for the planning and realisation of the extension building Sonne 2.0. We look forward to an accident-free and smooth construction period and ask for your understanding in case of any inconveniences caused by the construction.


October 2020 to April 2021

1st stage

After more than two years of planning, the ground-breaking ceremony for the extension took place on 19 October 2020. In the first stage, the construction of the new goods delivery area will be tackled first. This will be followed by the total renovation of the kitchen. In keeping with the concept of ecological and economic sustainability, the hotel will in future have a lakewater energy supply for heating and cooling.

Stage 3

From autumn 2021 the construction of 4 wellness suites can already be started. At the same time a gentle partial renovation of the existing rooms will take place. A photovoltaic system will be installed for the future power supply. In addition to these focal points, the entire façade will be renovated.
