Olympic Park Munich => Planned
Neuschwanstein Castle (Romantic Architecture) => Already proposed
Heidelberg Castle (Transformation from a Castle to a Palace) => Former
Parteitagsgelände Nuremberg (Nazi-Architecture) => Planned
Karl-Marx-Allee and Interbau 1957. => Planned
. Should be an extension, not a new site.
Eltz Castle / Burghausen Castle => Former
Gropius: Glaskathedrale Amberg => Already inscribed
2x (Fagus, Dessau)
Van der Rohe: New National Gallery, Weissenhofsiedlung => Already inscribed
(Tugendhat) and Le Corbusier. I didn't enjoy Weissenhofsiedlung much.
Gehry: Vitra Design Museum => Not yet the time.
Better than most of the newly proposed sites for the T-List.
Seeing several are on the proposed T-List, the existing T-List or a former T-List I think your statement is a bit too bold.
