Public Parklet
Gray becomes green in the city
Hello, Public Parklet. How can we demonstrate, in a concrete way, how simple means can be used to create a greener, more sustainable and pleasant urban environment? This was the question posed by some of our landscape architects and urban planners in the spring of 2015. During a seminar at the Stockholm office, they were to present “Green Retrofits”, strategies for transforming grey infrastructure into green infrastructure, and wished to illustrate, in practical terms, how much such interventions can contribute to the public realm.
From these reflections, an idea emerged. What if we could create a prototype of a micro-park – a meeting place for people in the city that simultaneously purifies stormwater and contributes to increased biodiversity? One that improves air quality and offers citizens a place for recreation and rest?



Micro-park on a parking space – Public Parklet
The team worked intensely for a few but productive weeks. On the day of the seminar, it stood assembled outside the entrance to the office at Katarinavägen 15 – “10 smarta kvadrat 2.0”. A micro-park on a parking space – a so-called parklet. Our guests and passing Stockholmers shared the seating in the temporary park, enjoying the sun, each other’s company and the unexpected vegetation in an otherwise rather grey and underused streetscape.
Public Parklet with stormwater management – the first in the world?
By combining ambitions for a more ecologically and socially sustainable city, we can, with simple means, create green spaces that contribute both to increased biodiversity and to encounters between people. Our parklet prototype is also, as far as we know, the first in the world to offer a solution for stormwater management. The idea is based on the functionality of so-called green streets: a swale filled with vegetation along the pavement edge. The delay created within the swale reduces runoff volume, while the vegetation captures environmentally harmful particles, resulting in smaller and cleaner stormwater discharges.
“Many people don’t realise that much of the inner city still relies on a combined stormwater and sewage system. This causes untreated sewage to be released into Lake Mälaren during heavy rain,” says planning architect Fredrik Legeby. “By introducing fixed urban biotopes as a connected system, we could create real benefits. For both the environment and the people living in the city.”
In fact, solutions of this kind may be closer in time than we think



Fewer cars create opportunities
Parking areas that perform ecosystem services. Does it sound utopian? In fact, solutions of this kind may be closer in time than we think. The needs of our streetscapes are changing as attitudes and habits around car use shift. Car pools, “car-to-go” services, rental bicycles and other transport alternatives are increasing. At the same time, technological development is advancing towards smaller and self-driving cars. Fewer and smaller vehicles can reduce the pressure on the city’s parking spaces, which can therefore be given new functions.
Parklets, small public spaces and micro-parks built on parking areas were introduced as a concept in San Francisco in 2010. Today, there are hundreds of them. Several cities around the world have since developed manuals for anyone interested in building a parklet, with guidelines for design, safety and maintenance.
“Sweden is lagging behind when it comes to this kind of sustainable thinking. We believe that micro-parks of this kind are a fully viable idea for the City of Stockholm. We would be happy to carry out pilot projects”.

The landscape and urban design teams in Stockholm came together to prepare “10 smarta kvadrat 2.0”. They installed it at Katarinavägen 15 in June 2015, and later donated it to the City of Stockholm Traffic Administration.
