6, rue de Hanovre, Art Nouveau office building in 2nd arrondissement, Paris, France

The 6, rue de Hanovre is a five-storey office building completed in 1907–1908, its 18-metre street facade clad in Art Nouveau glazed stoneware. Three large arcades span the ground and first floors, rectangular windows mark the second, and projecting bow-windows rise through the third and fourth. Marine motifs in green, ochre and sea tones cover the front, and the glazed entrance door carries wrought-iron work.

Architect François-Adolphe Bocage designed the building in 1908 as part of the Art Nouveau movement. He worked with enameler Alexandre Bigot to create a work that demonstrates the craftsmanship of this architectural period.

The facade displays starfish and shell motifs that reflect early 20th-century French decorative tastes. These ocean-inspired ornaments show the artistic language that shaped Paris during that period.

The building can be viewed from the street to study the facade details. Public access to the interior or rooftop is typically not available.

The centre of the building holds an octagonal courtyard, a feature not visible from the 18-metre street facade. The spiral staircase that crosses the building is lit by a set of stained-glass windows, and the entrance hall's horseshoe stair leads up to it.
