It had a suite of rooms on the left side of the building plot, flanked by a rather narrow entrance hall with stairs and a corridor that led to a small garden at the back.

He designed every single detail: door handles, woodwork, panels and windows in stained glass, mosaic flooring and furnishings.

Most other Art Nouveau dwellings in Belgium and other European countries were inspired by Horta's whiplash decorative style, which is mostly applied to a more traditional building.

The Hôtel Tassel had a decisive influence on the French Art Nouveau architect Hector Guimard, who later developed a personal interpretation of Horta's example.

Horta also diverged from typical architectural conventions by making the columns that dominate the front portion out of iron, as opposed to stone.

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.
