Sonnenstein Castle

Short description

Monument preservation in a PPP project – comprehensive renovation and conversion into a modern administrative centre.

The project

Sonnenstein Castle, which along with its grounds is classified as a national monument, was converted into a modern administrative centre and fitted out accordingly as part of extensive renovation work.

Following the extensive renovation of the historically significant castle complex, the new administrative centre offers a modern workplace for some 500 staff. In addition to the offices and consultation rooms, the development is rounded out by an assembly hall, an archive and a cafeteria. A car park with 277 parking spaces was constructed specially for staff and visitors. The reconstruction of the outdoor facilities, with a wealth of tree species within the grounds, was a great success.

Services in detail

The contract included project management, preliminary draft planning from phase 2 of the fee structure for architectural and engineering services (Honorarordnung für Architekten- und Ingenieurleistungen, HOAI), and renovation, conversion and fitting out of a historical castle complex, taking its status as a national monument into consideration. The services to be provided also included financing.

In a public tendering procedure, the Leipzig and Project Development branches of the Buildings division won out thanks to their wealth of experience in the fields of monument preservation and public-private partnerships (PPP). Sonnenstein Castle was one of the first projects to involve working to the strict requirements for listed buildings and monuments within a PPP model. The Project Development branch was responsible for financing and managing the project company. Meanwhile, the Leipzig branch entered into a joint venture with a regional partner in order to carry out the planning, renovation, conversion and fitting out of the complex.
