Boeri's studio Stefano Boeri Architetti won a competition to design Hawthorn Tower for a new district in the city's Jaarbeursboulevard area near Utrecht Central Station, which was recently completed by Bentham Crouwel Architects. It will be accompanied by a second tower designed by Dutch studio MVSA.
As with the earlier projects, the plants used on the mixed-use tower are intended to help absorb carbon dioxide and produce oxygen to improve the city's air quality. The vegetation covering Hawthorn Tower will amount to one hectare of woods, which the architect says will absorb 5.4 tonnes of carbon dioxide.
Hawthorn Tower will feature an urban forestation research centre on the ground floor called the Vertical Forest Hub to track Boeri's schemes, both in Europe and worldwide.
The upper floors of the building will be occupied by a mix of offices, fitness and yoga areas, bike parking places and a public leisure space.
Construction on Hawthorn Tower is slated to start in 2019 with completion expected in 2022.
Stefano Boeri Architetti also recently unveiled plans for a city near China's Liuzhou made entirely of vertical-forest towers. It forms part of the Forest City concept, which will see cities made up of plant-covered skyscrapers to eat up China's smog. Other projects in the scheme includes a design for city in Shijiazhuang and a pair of plant-covered skyscrapers in the centre of Nanjing.
