Bonnierhuset, Office tower in Vasastan, Stockholm, Sweden

Bonnierhuset is a 61-metre-high office building at Torsgatan 21 in Stockholm, designed by Ivar and Anders Tengbom and completed in 1949. Its facades are clad in yellow brick laid in a grid pattern. The tower holds editorial and office rooms, while the lower wing originally housed the printing works, bindery, and storage and distribution facilities.

The complex was built for the publisher Åhlén & Åkerlunds förlag, which needed offices and a printing works. Ivar and Anders Tengbom won the architectural competition in 1937, but the Second World War delayed the start of construction; the building was finished in 1949. It was Sweden's first concrete tower built after the war. The low wing held the printing press, bindery and distribution premises, and was extended in 1964 and 1972 with additions designed by Anders Tengbom.

The name Bonnierhuset is also used for the group's older head office on Sveavägen in Norrmalm. The tower held Bonnier's group management until 2008, when it moved to Kungsgatan; since April 2016 the management sits at Atlasmuren 1. The largest external tenant is the audit firm Öhrlings PricewaterhouseCoopers.

Bonnierhuset stands at Torsgatan 21 in Vasastan, just south of Vasaparken and a short walk from S:t Eriksplan metro station. Bonniers konsthall, Johan Celsing's 2006 gallery, occupies the former open terrace facing Torsgatan at ground level, not on an upper floor. The tower itself is a working office building, so visitors view the yellow brick facades from the street.

In 2006, the building's open terrace was transformed into Bonniers konsthall, an art gallery showcasing contemporary works. This conversion blends the building's commercial past with a new cultural purpose that visitors can experience today.
