The building occupies a large corner site covering four separate plots and addresses along Drottninggatan, and although it appears from the street to be four distinct buildings from different eras, it is in fact a single large office complex. It was designed by architect Carl Nyrén and built between 1986 and 1989, replacing an earlier commercial building of 1906 that had itself stood on the site of a 17th-century palace.
The most unusual feature is the central section, where the original facade of a demolished building elsewhere in the city was carefully preserved and later reassembled on this new structure. This was possible because the facade had been built using a curtain wall method, allowing it to be removed intact and stored for around fifteen years before being remounted. The old house number from its original location can still be seen above the entrance.
The building's design earned a major Swedish architecture award shortly after completion, and it has since been recognised by Stockholm's city museum as being of particularly high cultural-historical value, among a group of buildings from the 1960s to 1980s considered especially significant in the Norrmalm district.
Visitors interested in the area's history may also note that an American technology company had its Stockholm office in the corner building on this site for several decades in the mid-20th century, before the current structure was built.
