Press Release

KY Building (the old business students’ union building), in the Helsinki city centre, will be named Kulma21 in the future. The building will be renovated into a multifunctional business space to support modern working culture. The building will be the first one in Finland to be certified Excellent as per the latest criteria of the BREEAM environmental rating system for renovation projects.  

- By giving the building the simple name ’Kulma21’ (’Corner21’) we want to honor the building’s history, spirit and traditions, but also refer to its location at Pohjoinen Rautatie 21. Kulma21 will be a business space to meet many different demands, including mobility of both the companies and the people. The top floor with its glass walls and roof terraces gives the building a nice touch-up. The flexible space solutions range between 200 and 6000 sq. m. and are well suited for a wide variety of companies and businesses. Owing to its central location, excellent traffic connections and top visibility, the building is a perfect choice for headquarters, Property Developer Matti Partanen of NCC says.

- The main objective of the refurbishment work is to restore the full value of the building that has gotten shabby over the years, Principal Designer Hanna Koskela and Design Director Petrus Laaksonen of Tengbom say. The façade materials are renewed to better correspond to the original materials. The topmost floor is practically re-built, which enables implementing the façade opening towards the roof terrace as a continuous glass surface. The vertical framing founded over the building’s columns allows for flexible space planning. Although the basic floors of the students’ union building were originally designed for living, the building lends itself beautifully to office use.

The design and renovation of the building are supervised by the BREEAM environmental rating criteria with the overall target to achieve an ecologically, socially and financially sustainable building for its entire life cycle.

- The central location already supports our targets for sustainability, since the building is accessible by many different modes of transport. Sustainability is also seen as safe material choices that are made considering their carbon footprint. The spaces will be modifiable for many different uses, Partanen describes.

NCC bought the building from the Business Students’ Union in late 2020. It has a unique history as a prominent centre for student life, business, entertainment and spare-time activities. The building is listed by the National Board of Antiquities as a property of built cultural environment of significant national value. Extensive renovation of the building will start in April with interior demolition work. The project is expected to be completed in 2023.
