A new kind of modular green wall by Parkly and Innogreen is part of an experiment run by the city of Helsinki to examine how a green wall can serve as a barrier against traffic noise. The purpose of the wall is to create an oasis with a pleasant soundscape and seating. The vegetation and the shade provided by the wall also offers a cooler place to sit down on a hot day. Most of the various plants are pollinator friendly. 

The modular green wall has been developed to bring more greenery and comfort to the urban environment. Research has shown that greenery increases well-being and multi-species vegetation increases biodiversity in cities.

WSP consultancy is responsible for the acoustic design of the wall and will study the impact of the structure and vegetation on the reduction of traffic noise during the summer. WSP has also been involved in consulting the wall’s compatibility with the square’s cityscape.

​​We are collecting information from users and developing different variations of the modular wall for different spaces. The modular green wall is available in various sizes and fits perfectly for street implementations, roof terraces, work and study environments and various other public spaces.
