La Caixa Building, Modern building in Almagro district, Madrid, Spain.

The La Caixa Building is an eight-storey office block at 51 Paseo de la Castellana, on the corner of Miguel Ángel and García de Paredes streets in Madrid's Almagro neighbourhood. Designed by architect José María Bosch Aymerich, it has chamfered corners whose width varies with height. It serves as the Madrid headquarters of the La Caixa banking foundation, whose main seat is in Palma de Mallorca.

The office building at 51 Paseo de la Castellana was designed by architect José María Bosch Aymerich in 1978 and opened as La Caixa's Madrid headquarters around 1980. Part of it was sold in 1992, and the Catalan company regained full ownership in 2008.

The building is the Madrid headquarters of the la Caixa banking foundation, whose main seat is in Palma de Mallorca. It is an office building, not a museum: the foundation's cultural work in the city is run from here, while the Catalan company sold part of the property in 1992 and bought it back in full in 2008.

The office building stands at 51 Paseo de la Castellana, on the block formed with Calle de Miguel Ángel and Calle García de Paredes, in the Almagro neighbourhood of Chamberí. Its corners are chamfered, and the width of these cut corners changes with height, a detail visible from street level. It is the Madrid seat of the La Caixa banking foundation, whose main headquarters is in Palma de Mallorca.

The corners of the building are chamfered, and the width of these chamfers changes with height, so the profile shifts as you look up the facade. The Catalan company sold part of the building in 1992 and regained ownership of the whole property in 2008.
