The high-rise buildings of Trigoni with an equilateral triangular geometry will create a unique sculptural landmark of international standards in Pasila. Trigoni combines commerce, workplaces and housing. Together with an excellent location these will create the excellent conditions for the second urban centre of Helsinki, which is alive round the clock and year-round.
The implementation of the start-up area includes the construction of two high-rise buildings and a podium structure. According to the proposal, the first high-rise in the start-up area, which will also be the tallest building in the area, will reach a height of approximately 180 metres and have a total of 51 storeys. The building is designed to include a hotel, apartments and a scenic restaurant. The other high-rise, approximately 140 metres tall and with 40 storeys, will house offices and apartments. The podium will include commercial premises, street-level storefronts and parking facilities. The start-up area is estimated to incorporate approximately 500 apartments, 300 hotel rooms and workplaces for 1,000 people. The construction of the start-up area could commence approximately 2020–2021 after the city plan has been confirmed.
Trigoni’s urban space quality is generated between the contrast of high and low. The planning of the tower area takes into account the human scale, which is reflected in the pleasant pedestrian environment it provides. Design solutions of the low podium offer weather-protected passages that entice to arrive and stay. The pavilion in the tower square and the open space surrounding it create natural meeting spots for those arriving in the area.
In early October 2018, YIT’s Trigoni plan was nominated to win the Helsinki High-rise Design-Build Competition which was organized by the City of Helsinki and Senate Properties. In February 2019, an agreement was signed between YIT, the City of Helsinki and Senate Properties on the implementation of the first phase of the project (start-up area) and the purchase of the start-up area.
