Kulma21 – Classic’s new future

The former students’ union building of Helsinki School of Economics will be renovated into multifunctional office and retail space to build the happy working culture of tomorrow. The renovation will be carried out with all due respect to tradition. The building will be named Kulma21 (”Corner21”).

Kulma21 is located at Pohjoinen Rautatiekatu in Kamppi district of Helsinki city centre. The site is extremely well served by traffic connections. Within a short walking distance are the Musiikkitalo concert hall and the Oodi central library. The area creates a dynamic urban entirety where everything comes together: generous services, work, entertainment and a truly urban way of life.
