Hôtel Tassel (1892–93) The major breakthrough for Horta came in 1892, when he was commissioned to design a home for the scientist and professor Émile Tassel. The
Hôtel Tassel was completed in 1893. The stone facade, designed to harmonize with the neighboring buildings, was fairly traditional, but the interior was strikingly new. Horta used the technologies of glass and iron, which he had practiced on the
Royal Greenhouses of Laeken, to create an interior filled with light and space. The house was built around an open central stairway. The interior decoration featured curling lines, modeled after vines and flowers, which were repeated in the ironwork railings of the stairway, in the tiles of the floor, in the glass of the doors and skylights, and painted on the walls. The building is widely recognized as one of the first appearances of Art Nouveau in architecture (along with the
Hankar House by
Paul Hankar, built at the same time). In 2000, it was designated, along with three other town houses designed soon afterwards, as a
UNESCO World Heritage Site. In designating these sites, UNESCO explained: "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."

Hôtel Solvay (1895–1900) The
Hôtel Solvay, on the
Avenue Louise/Louizalaan in Brussels, was constructed for Armand Solvay, the son of the chemist and industrialist
Ernest Solvay. Horta had a virtually unlimited budget, and used the most exotic materials in unusual combinations, such as marble, bronze and rare tropical woods in the stairway decoration. The stairway walls were decorated by the
pointillist painter
Théo van Rysselberghe. Horta designed every detail including the bronze doorbell and the house number, to match the overall style. File:BE Bruxelles Horta Solvay.JPG|Facade of the

Hôtel Van Eetvelde (1895–1901) The
Hôtel van Eetvelde is considered one of Horta's most accomplished and innovative buildings, because of highly original Winter Garden interior and the imaginative details throughout. The open floor plan of the Hôtel Van Eetvelde was particularly original, and offered an abundance of light, both horizontally and vertically, and a great sensation of space. A central court went up the height of the building, bringing light from the skylight above. On the main floor, the oval-shaped salons were open to the courtyard, and also received light from large bay windows. It was possible to look from one side of the building to other from any of the salons on the main floor. File:Belgique - Bruxelles - Hôtel Van Eetvelde - 01.jpg|Facade of the

Horta House and Studio (1898–1901) The Horta House and Studio, now the
Horta Museum, was Horta's residence and office, and was certainly more modest than the other houses, but it had its own original features and equally fine craftsmanship and mastery of details. He made unusual combinations of materials, such as wood, iron and marble in the staircase decoration. The novel element in Horta's houses and then his larger buildings was his search for maximum transparency and light, something often difficult to achieve with the narrow building sites in Brussels. He achieved this by use of large windows, skylights, mirrors, and especially by his open floor plans, which brought in light from all sides and from above. File:Hortamuseum.tif|The

Hôtel Aubecq (1899–1902) The Hôtel Aubecq in Brussels was one of his late houses, made for the industrialist Octave Aubecq. As with his other houses, it featured a skylight over the central staircase, filling the house with light. Its peculiarity was the octagonal shape of the rooms, and the three facades with windows, designed to give maximum light. The owner originally wished to keep his original family furniture, but because of the odd shape of the rooms, Horta was commissioned to create new furniture. By the mid-1930s, Art Nouveau was out of fashion, and modernist architects argued that the old Art Nouveau mansions should be replaced by tall apartment buildings. In 1936, critic Pierre Gilles took aim at the Hôtel Aubecq: "A pampered building that unrepentantly recalls those airy-fairy years." The creation of "an aesthete-architect", its "drooping floral lines" resembled faded coastal casinos and the work of humorous illustrator
Albert Robida, he wrote...

Maison du Peuple (1896–1899) While Horta was building luxurious town houses for the wealthy, he also applied his ideas to more functional buildings. From 1896 to 1899, he designed and built the
Maison du Peuple/Volkshuis ("House of the People"), the headquarters for the
Belgian Workers' Party (POB/BWP). This was a large structure including offices, meeting rooms, a café and a conference and concert hall seating over 2,000 people. It was a purely functional building, constructed of steel columns with curtain walls. Unlike his houses, there was virtually no decoration. The only recognizable Art Nouveau feature was a slight curving of the steel pillars supporting the roof. As with his houses, the building was designed to make a maximum use of light, with large skylights over the main meeting room. It was demolished in 1965, despite an international petition of protest by over 700 architects. The materials of the building were saved for possible reconstruction, but were eventually scattered around Brussels. Some parts were used for the construction of the
Brussels Metro system. File:Maison du Peuple of the P.O.B.

craftsmanship. Beginning in 1903, he constructed the Grand Bazar Anspach, a large
department store, with his characteristic use of large windows, open floors, and
wrought iron decoration. In 1907, Horta designed the
Museum for Fine Arts in
Tournai, although it did not open until 1928 due to
World War I.
Magasins Waucquez (1905–06) The
Magasins Waucquez (now the
Belgian Comic Strip Center) was originally a department store specializing in textiles. In its design, Horta used all his skill with steel and glass to create dramatic open spaces and to give them an abundance of light from above. The steel and glass skylight is combined with decorative touches, such as neoclassical columns. After Waucquez's death in 1920, the building began to languish away, and in 1970, the firm closed its doors. Jean Delhaye, a former student and aide of Horta, saved the building from demolition, and by 16 October 1975, because of its connection to Horta, it was declared a
protected monument. Now a museum of a particular Belgian speciality, the
comic strip, it also has a room devoted to Horta. File:Brussel - Zandstraat 20 - Belgisch Stripcentrum in het voormalig Waucquez-warenhuis (1903 door Victor Horta) 20230826.jpg|Facade of the former

Brugmann University Hospital (1906) In 1906, Horta accepted the commission for the new Brugmann University Hospital (now the Victor Horta Site of the Brugmann University Hospital). Developed to take into account the views of the clinicians and hospital managers, Horta's design separated the functions of the hospital into a number of low-rise
pavilions spread over the park based campus, and work began in 1911. Although used during
World War I, the official opening was delayed until 1923. Its unusual design and layout attracted great interest from the European medical community, and his buildings continue in use to this day. ==The First World War – travel to the United States==
