The most valuable real estate asset of the Gremi Group is the Alvernia Planet complex, owned by Alvernia Planet sp. z o.o., a company that is part of the KCI SA group. The main part of the complex consists of buildings with a total area of 17,425 m², including 13 domes connected by glass-covered walkways and a second set of buildings. The total property area owned by Alvernia Planet exceeds 14 hectares. Adjacent to the buildings are parking facilities with 300 spaces, with the potential to expand to 1,000 spaces.

The complex is located between Kraków and Katowice, within a 100 km radius of 8 million residents from two Polish regions: Małopolska and Silesia. It is situated near an exit from the A4 motorway, close to Kraków—a city visited by 12 million tourists annually—and near two major international airports. In addition to its excellent transportation links, the location boasts a unique natural setting: it is surrounded by the green landscapes of the Tenczyński Landscape Park and the ruins of the Tenczyn Castle.

The complex was originally created by its founder as a film and sound recording studio. Gremi Group acquired the property in August 2017. The new project concept envisions transforming the entire area into a modern center for attractions, entertainment, and education.

The first B2C project to be implemented is this year's Harry Potter: The Exhibition, which will open on April 11, 2025—exactly on the 25th anniversary of the premiere of the first story about the young wizard, Harry Potter and the Philosopher's Stone. Harry Potter is the most popular youth book series in the world, telling the story of an orphan and outcast who turns out to be a wizard! The Harry Potter books are beautiful tales of friendship and courage, which have rightfully been called the bestsellers of all time.

The anticipated attendance at Alvernia Planet this year is expected to reach 450,000 visitors.
