Ympyrätalo is one of Helsinki's most recognisable office buildings and a landmark of Hakaniemi, known simply by its name. The building was completed in 1968 for Kansallis-Osake-Pankki, designed by architects Heikki and Kaisa Sirén. Its circular shape is not merely stylistic but defines the nature of the spaces, offering exceptional flexibility in floor plans. The building has nine floors, each approximately 2,670 m². It is protected by the Finnish Heritage Agency, covering the façade, entrances, inner courtyard, and stairwells. The building underwent a major renovation in 2004, renewing surfaces and technology while respecting its original spirit. Its location by the seaside offers some spaces views over Tokoinranta and the city.

The building features a reception, lunch restaurant and café, gym, and social facilities with showers. At street level there is an S-Market and restaurants, and parking is arranged in the building’s car park. Users benefit from bicycle parking and electric vehicle charging points. The property also has a conference and training room named Gustav. The surrounding area is exceptionally rich in services, with Hakaniemi Market Square, market hall and a wide selection of lunch restaurants and other amenities within walking distance.

Accessibility is one of Ympyrätalo's strengths. The Hakaniemi metro station entrance is right next to the property, as are tram and bus stops. Helsinki Central Railway Station is approximately 1.3 kilometres away, and Helsinki-Vantaa Airport around 18 kilometres. Its location at the northern end of Pitkänsillan makes the building easily accessible by public transport and on foot.

Ympyrätalo has been awarded the BREEAM In-Use environmental certification at the Excellent level. The property's electricity is generated using Finnish wind power.
