The main building of the field station was completed in 1872.
The accommodation capacity of the Krunni's field station is 14 people in winter and 20 people in summer. The main building has a high-quality kitchen for a field station, only running water and refrigeration equipment are missing from the kitchen (found from the cabin).
During summer time, the Krunni's field station has a solar-powered electrical system with enough capacity to recharge computers, batteries for research equipment and for running smaller electrical equipment. The system can also be reasonably loaded with a microwave and refrigerator. In winter, the battery of the solar-power system is kept alive with a small wind turbine. For winter use, the station has an internal combustion aggregation unit, with a capacity of about 6 kw.
The sauna building in the field station can accommodate four people.
