The Otto Wulff Building (also sometimes written Otto Wulf) is a unique building, in the Jugendstil or German modernism style, which is located at the intersection of Avenida Belgrano and Calle Perú (Belgrano 601) in the Monserrat neighborhood, in the City of Buenos Aires, Argentina.
The construction that began in 1912 and ended in 1914 was carried out at the request of the businessman Otto Wulff in partnership with the shipowner Nicolás Mihanovich
It was one of the many works carried out in the country by the Danish architect Morten F. Rönnow —of the Jugendstil school— (together with the Danish Church in San Telmo, the headquarters of the Swiss embassy in Barrio Parque and several rooms and buildings of single-family home among others)1 in the double capacity of designer and construction manager. The construction, for which materials were brought from Europe, was carried out by the Dutch engineers Pieter Jacobus Dirks and Willem Hendrik Johannes Dates.
