It was designed by Victor Horta for Edmond van Eetvelde, administrator of Congo Free State, and built between 1895 and 1898, in Art Nouveau style.

The Hotel van Eetvelde in Brussels was designed in 1898[sic] by Victor Horta, undoubtedly the key European Art Nouveau architect.

The Hotel van Eetvelde is a remarkable example of the way Horta handled the situation and used it to highlight the imposing staircase, which leads up to the first-floor reception rooms.

[5] The cupola with its coloured stained glass windows is supported by eight steel columns, which "are integrated into this vegetal world like rods".

The stylistic revolution represented by these works is characterised by their open plan, the diffusion of light, and the brilliant joining of the curved lines of decoration with the structure of the building.
