The Sello shopping centre in Espoo attracts thousands of visitors daily. The shopping centre has turned into more of a meeting place rather than just a concentration of shops. People come to spend time and enjoy themselves with friends and family. This makes the cosiness of both the inside and outside spaces more important than it used to be. We have been cooperating with the Sello shopping centre for a long time. This time around, our mutual goal was to create a unique eye-catcher.
In Europe, green walls and surprising green decor solutions are a bit more common than in Finland, but change is clearly in the air. “It is noticeable that the traditional pot planting isn’t enough anymore. People want something more special, something to create experiences,” says Jaakko Pesonen, one of the founders of InnoGreen and wizards behind the green tower.
The idea to build a green tower came from Sello’s passion for environmental issues. With the green tower, Sello wanted to highlight important values concerning recycling and the environment in celebration of being the first European shopping centre to receive a Leed certificate, and of course to further improve the cosiness of the shopping centre. The 900 plants in the tower wer planted, or bagged, into SACK growing bags together with Sello customers.
Tornia varten rakennettiin automaattinen altakastelujärjestelmä sekä alumiinikehikko, jota ympäröi kasviosat. Kuhunkin hyllyä muistuttavaan kasviosaan mahtuu neljä kasvia, ja jokaiseen tornin kerrokseen yhteensä 12 kasvia. Tornin altakastelujärjestelmä takaa sen, että kasvit kautta tornin saavat juuri oikean määrän vettä ja ravinteita pysyäkseen kukoistavina. (Lue lisää kasviseiniemme teknisestä toteutuksesta.)
The plants in Sello’s green tower are regularly maintained. We also place seasonal plants in the tower to make sure it stays marvellous.
“We are expecting a “wow” effect. And for news to travel by word of mouth that there’s something new and amazing to see in Sello again,” explains Sanna Kouvalainen, the marketing director of the Sello shopping centre.
The Circular Green Wall, piloted during summer 2025, utilizes deconstructed facade panels and soil rescued from construction sites.
How to choose green interior solutions and plant care more sustainably? At first glance, choosing indoor greenery might seem straightforward. Which plants should we pick, and where should we place them? And where can we get them at the lowest cost? A low price can be tempting, and comparing quotes is always worthwhile. But when an interior green solution is viewed as a long-term investment, the cheapest option can quickly generate unexpected costs. Here’s what truly goes into the price of high-quality, sustainable green interiors.
In the spring of 2025, Finland’s largest outdoor green wall was completed on the façade of Turun Teknologiakiinteistöt’s property in Turku. The 16-meter-high vertical garden is the first in the country to utilize stormwater for irrigation. It has attracted attention for both its impressive scale and innovative technology. But how are the wall, its plants, and its irrigation system doing after their first growing season?
