Aaltohuset, Office building in Avesta, Sweden.

Aaltohuset is a commercial and residential building in Avesta, designed by Finnish architect Alvar Aalto with Albin Stark. It is also called Blå huset, the blue house, after the blue ceramic tiles on its facade. It is one of only two preserved buildings in Sweden drawn by Aalto; the other is Västmanlands-Dala nationshus in Uppsala.

Finnish architect Alvar Aalto designed this building between 1957 and 1961 as a commission from local businessman Ernst Sundh. It stands as one of only two buildings Aalto created in Sweden, making it a rare example of his work outside Finland and a marker of modernist influence in the region.

The blue ceramic tiles from Finland that cover the facade tell a story of design crossing borders during the 1950s. These tiles remain visible today as a reminder of how this corner of Avesta connected to broader Scandinavian artistic movements.

Visit during business hours to see the shops and offices in use, which gives a real sense of how the place functions today. The corner location makes it easy to find and access on foot, with parking available nearby.

The building is also known as Blå huset, the blue house, after the blue ceramic tiles on its facade. It is one of only two surviving buildings in Sweden designed by Alvar Aalto; the other is the Västmanlands-Dala nation house in Uppsala.
