The historical building is the focal point of the redevelopment and becomes the main exhibit; the addition of a new building shifts the rear façade to the centre of the resulting new museum.
The extension is located directly behind the existing building and is based on a partial replication of the latter’s cross-section, as such incorporating the form and scale of the original and reinterpreting them via a bold and modern architectural vocabulary. The result is a harmonious synthesis of two buildings. On the outside the museum has two complementary façades: the original one featuring the main entrance and facing the town centre and the new, modern rear side looking on to the museum garden.
