Input: Question: How many homes did the architect of the Yablanski House design? Passage:The Yablanski House was built in 1906-1907 to the designs of Austro-Hungarian architect Friedrich Grünanger (1856–1929) on the order of the wealthy financier and former mayor of Sofia Dimitar Yablanski (1859–1924). The exterior decoration was the work of the royal decorator of the Bulgarian Royal Family, Andreas Greis. Architecturally, the house was designed in the Baroque style with some Renaissance elements, with the interior stucco done in the Rococo style. The mansard floor is an important feature of the house's artistic design, together with the balcony railings of wrought iron and the several female sculptures. The furniture and the materials were specially supplied from Vienna. The house's architecture draws heavily from an earlier work of Grünanger's, the Royal Palace in Sofia. Notably, the architect's home in Salzburg, where he later moved and subsequently died, is almost identical to the Yablanski House.
