Called Wilmina, the hotel occupies a duo of listed 19th-century structures in Charlottenburg that had been forgotten for decades prior to their renovation.
The former court, which sits at the entrance on Kantstraße, accommodates the hotel's reception as well as a temporary gallery called Amtsalon.
An extension housing Wilmina's restaurant connects the courthouse to the prison's U-shaped cell block, which fits 44 guest rooms across five levels including a new penthouse floor at the top.
Grüntuch Ernst Architects also added a roof terrace above the penthouse alongside a library, bar, spa and gym.
