The pilot year of Puistokatu 4 in pictures – a Space of Science and Hope provided a meeting spot for presidents, toddlers, researchers, artists and more in 2023

In the pilot year of Puistokatu 4, the house hosted more than 50 events, with around 2000 people envisioning a good life within planetary boundaries. In the Puistokatu community, 29 researchers and 19 agents built a more ecologically sustainable future.

The events at Puistokatu 4 reached around 2000 people in 2023. Julia Thurén’s parents’ circle provided peer support for climate-anxious parents of young children.


The Puistokatu 4’s library was open to all throughout the year. The library also hosted the Sustainable City Reading Circle, led by Johanna Vuorelma, Riikka Suominen and Inari Virkkala.

Members of Puistokatu 4 created a community


In the pilot year, the Science Attic of Puistokatu 4 hosted 29 researchers representing almost as many disciplines i.e. economics, biology and architecture.


“My time at Puistokatu was full of interesting encounters, educational events and peer-support lunches,” says Roni Lappalainen, a researcher of the Science Attic.


Through our Researcher Lunch concept a total of 30 curious people came to learn about the work of our researchers over lunch at Restaurant Elm.

A total of 19 agent members worked at Puistokatu 4 during the year. The community included startups, activists and foundations.


“Puistokatu 4 has provided a unique opportunity to be part of a community where everything is tinged with meaning,” says Efe Evwaraye of Timeout-Foundation, a member of Puistokatu 4.


“The most important thing about Puistokatu 4 is the community that has formed here over the year. Everyone is interested in an ecologically sustainable future and comes together from different backgrounds,” says Terhi Vapola of Greencode Ventures.


Politicians and business leaders gathered in Puistokatu 4


In February, Climate Crisis Masterclass was held at Puistokatu 4, bringing together politicians, business leaders and environmental scientists. The event featured speakers such as Johan Rockström, John Kerry and President Sauli Niinistö.



In October, we organised a Biodiversity Leadership Course, which brought together 25 business leaders to learn about biodiversity. The course was led by ecologists Anna-Liisa Laine and Tomas Roslin.


At the Operation Arctic election panel in March, Atte Harjanne, Mai Kivelä, Nea Nättinen and Lauri Muranen were asked how climate policy fits into the constraints of physical reality.


Difficult themes approached through art


Art was also enjoyed at Puistokatu 4 during the pilot year. On the Night of the Arts on 25 August, Sonja Salomäki’s Planetbic brought planetary aerobic to our yard.
