Casa Mappin & Webb, Academic art building in San Nicolás, Buenos Aires, Argentina

Casa Mappin & Webb is an academicist building on Calle Florida whose lower levels are pale beige stone and whose upper structure is clad in grey-and-white vertically striped material. Two large arched bays with dark metal grilles open at street level, with balconies with ornate dark metal railings above them. A white sign with red HSBC lettering and the number 0810-333-4722 is mounted at street level.

Casa Mappin & Webb was projected in 1911 as the Buenos Aires branch of the London jewellers Mappin & Webb, in the San Nicolás neighbourhood, when Calle Florida was the city's main aristocratic street and Avenida de Mayo, finished in 1894, concentrated the big shops and offices; Diagonal Norte had not yet been opened. The academicist building later passed to Banca Nazionale del Lavoro and is now an HSBC branch, which also owns the adjoining Edificio Florida 40.

The building showcases classical artistic principles that shaped Buenos Aires in the early 1900s, with its ornate stone facade reflecting the European tastes that influenced the city at that time.

The building currently functions as a bank branch and sits in an easily accessible location on Florida Street. The position offers good connections to public transportation and is surrounded by numerous other shops and services.

The cup made by William Bellchambers in 1841 was not the model Queen Victoria chose for the Royal Yacht Squadron. It reached the Buenos Aires branch years later and was bought there in 1940 to be awarded as the Copa Los Andes golf prize.
