It is sometimes called the Strykjärnshuset (Flatiron Building) because it sits on a wedge-shaped plot between Birger Jarlsgatan, Biblioteksgatan, and Stureplan, in the Östermalm district in the city center.

[1] The building is recognizable by its steeply-pitched conical tower and its richly decorated limestone facade in an early French Renaissance style.

[3] The client's initials, an intertwined BATH, are found above the portal towards Birger Jarlsgatan, on the tower towards Stureplan and towards Biblioteksgatan on small coats of arms.

The facade was originally intended to be covered in brick, but at the last minute it was changed to natural limestone from Yxhult, which at the time was seen as modern and authentic in contrast to the older stucco or plaster architecture.

This bourgeois turn-of-the-century architecture, which recycled historical forms of expression, generally rejected the internationally prevailing Art Nouveau style that had also come to Sweden.

[5] After Danelius' death, the building was replaced by his daughter Ebba Lovisa, who continued her father's philanthropic activities and in 1930, among other things, let Stockholm University's Humanities Library (“HumB”) keep an electricity-free apartment on the 1st floor.

The estate of Ebba Lovisa Danelius sold the house in 1964 for SEK 4 million to the construction company Nils Nessen AB.

Stockholm resident Per Lindeberg took the initiative and drew up an open protest letter, which was signed by about twenty prominent cultural personalities, including the authors Bo Bergman, Per Anders Fogelström, Barbro Alving (Bang), Svante Foerster, the art critics Gotthard Johansson and Ulf Linde and several respected representatives of the architectural community.
