The building design was drafted by the stage designer Christian Jank and realized by the architect Eduard Riedel. For technical reasons the ruined castles could not be integrated into the plan. Initial ideas for the palace drew stylistically on Nuremberg Castle and envisaged a simple building in place of the old Vorderhohenschwangau Castle, but they were rejected and replaced by increasingly extensive drafts, culminating in a bigger palace modelled on the Wartburg.The king insisted on a detailed plan and on personal approval of each and every draft.Ludwig's control went so far that the palace has been regarded as his own creation, rather than that of the architects involved.
Whereas contemporary architecture critics derided Neuschwanstein, one of the last big palace building projects of the 19th century, as kitsch, Neuschwanstein and Ludwig II's other buildings are now counted among the major works of European historicism.For financial reasons a project similar to Neuschwanstein – Falkenstein Castle – never left the planning stages.
The palace can be regarded as typical for 19th century architecture. The shapes of Romanesque (simple geometric figures such as cuboids and semicircular arches), Gothic (upward-pointing lines, slim towers, delicate embellishments) and Byzantine architecture and art (the Throne Hall décor) were mingled in an eclectic fashion and supplemented with 19th-century technical achievements.
