The late Art Nouveau Forbáth or Müller mansion was built on the southern corner of Dugonics square in 1911-1912. The building was designed by Lipót Baumhorn. During the Great Flood of Szeged, the house on the plot was owned by town clerk János Reizner. As the city was rebuilt, a new triangle-shaped plot was created around the corner of the square. The apartment building of Leo Forbáth, a doctor in Szeged, was built on the place of the old one-storey house, a huge corner building that significantly influenced the appearance of the square. The building permit for the impressive three-storey mansion overlooking the three streets was issued to the owner on June 21, 1911, and the residence permit was granted just one year later, on April 27, 1912. On the ground floor there were shops, and above them rented apartments.
The brilliant shape of the facade ornaments as well as the design and arrangement of the balconies show many similarities with Baumhorn’s other apartment houses in Szeged; in addition, the decorations often used by the architect are also present: historicizing and geometricizing shapes, masks, columns. Beside the straight windows, on the third floor we can see trapezoidal ones, which is a popular Art Nouveau form of windows and doors.
The central part of the building facing Tisza Lajos boulevard has a prominent role: there are long balconies and a characteristic pediment that is oval in the centre, as well as a window with glass dividing strips.
The ornamental wrought iron work of the building was made by Antal Kecskeméti, a master from Szeged. In the pattern of its gates, besides the repetitive angular pattern, we can also discover the motifs of the poppy-cone, which are not widespread in Szeged.
