Transformation of previously derelict areas

A formerly derelict area, part of a 19th-century estate, the Zurich Square is a park, whose whereabouts are relatively new, and whose main function is to serve as the only park for the 700 children of the neighbourhood. Its location makes it also valuable, meaning that this park is situated in an industrial area and it contains trees planted in the 19th century (1).

The OrtoCollettivo project focuses on the creation of common spaces to grow local sustainable food while raising awareness about environmental challenges in cities. The project is based on teamwork: if there is work planned for today and someone cannot come to do that job, someone else will do it, with the ultimate benefit of everyone. It, therefore, stimulates common values about well-being, sustainable food production, and sharing time and activities collectively as a group (2). The initiative is ongoing and expanding, however in 2020 there were voices from the people living in the area that the poor maintenance of the terraces caused landslides and disturbed traffic. Nevertheless the NGO that initiated the intervention defended the project and suggested that the issue is caused by the lack of canals for the rain water to flow in. (8)

The association Initial Karlsruhe initiated the "social garden" in 2009 with the objective to facilitate access to the labour market for disadvantaged individuals by providing employment for long-term unemployed individuals with gaps in their CV. (Ref. 1) The participants can work on a 6000 sqm large former agriculture area up to six hours per day under the supervision of an agrarian engineer and a professional gardener. Harvested products are delivered by bicycle to charitable organizations free of charge. (Ref. 2, 9, 10)

Craigmillar Town Centre Temporary Greening project transformed a vacant development site in Craigmillar which is reserved for a new high school, not scheduled to be built until late 2020, into a temporary green space. The site is at the centre of the wider Craigmillar regeneration area, adjacent to the newly-built Community Hub and neighbouring plots at varying stages of development. EDI's PARC Craigmillar Ltd is responsible for the regeneration in Craigmilar, working in partnership with Edinburgh & Lothians Greenspace Trust (ELGT) and the City of Edinburgh Council. The initiative will create a meanwhile space for community use, while works begin on the town centre development. The greening will allow the area to become an active space for the local community to enjoy and ease the construction process. Craigmillar Town Centre Temporary Greening forms part of a wider plan for the redevelopment of Craigmillar Town Centre. The masterplan, which was approved in December 2014, includes 330 homes, a retail centre, restaurant, community play area and high school – where the temporary greenspace will be situated until building commences.

Love Square is a combination of nature and wildlife with a social space for residents and workers. The area has wildflower meadows, lawns and a mini wetland lined with bird-friendly trees (ref 2). Love Square is one of the examples of a new type of ‘smart’ -urban eco-park, combining nature and wildlife with artworks, social and activity spaces. It has a ‘Rain Garden’ and mini wetland that will soak up excess rainwater. It is a prime example of ‘water-sensitive Urban Design (ref1). The rain garden is designed to provide essential urban “greening”; increased soil and vegetation coverage will be able to soak up extra rainfall after a storm, will help to reduce the danger of flash flooding (ref 5).

"Pending the creation of housing and new walks by 2020, the association Carton Plein and the EPA (Public Building Institution) of Saint-Etienne have created a temporary public space on the site known as "la Cartonnerie". A place for exchange and conviviality, the site hosts artistic installations, ephemeral installations and events. It is a laboratory conducive to imagining new ways of doing the city" (Ref. 1). The citizens also created shared gardens in this area called "Le Jardin Experimental"(Experimental garden) (Ref. 4).

This intervention is about the restoration of the riverbanks of the Janon River along a street in the Terrenoire District of Saint Etienne. This area was abandoned for more than 10 years, without maintenance and cleaning. Therefore, this intervention was mandatory for clean up to avoid flood as well as bringing back vegetation and offering some quality walking areas for citizens (Ref. 1).

The Leonardo Garden was a community garden in an empty building site of 8th district of Budapest, that implementation was initiated by KÉK, the Contemporary Architectural Centre. (Reference 3)
The recultivation of two neglected, empty plots of land created one of the earliest community gardens in Hungary. Plants for consumption, spices, herbs and ornamental plants were planted. The 95 plots in the Garden were cultivated by young people, families and pensioners, but the Garden also served educational purposes, as it frequently received school groups. The Garden has hosted a number of public community and cultural, gastronomic and musical events, which were well attended by both the neighbourhood and the general public. The community garden was closed in March 2018 because the company that owns the land wanted to start construction on it. (Reference 5)

Hellenikon Metropolitan Park will be a large urban park located in Hellinikon, Athens, Greece. The park will be the central attraction of the Hellinikon project. It will provide Athens with a much needed ecological boost. When finished the park will be the largest in Europe. It will be approximately 200 hectares spanning the site of the former Hellenikon International Airport (Ref 4). The project will follow an integrated approach to sustainability. The objective is to boost greenery and create high-quality spaces while minimizing the natural resources used, protecting and enhancing the ecosystems in the region, and also raising awareness and educating the public on sustainability issues (Ref 1). Initially, the project was planned to start in 2008 and to be completed by 2013, but with the unfortunate and unseeing financial crisis worldwide, was shelved. A part of the project has been completed in the first 5 years. In 2013, a new design strategy for the project was submitted as part of The Hellinikon Project. The team included Foster & Partners, Charles Anderson Landscape Architecture, ARUP and a group of Greek design consultants. The design was revised and resubmitted to the Greek government in 2018 (Ref 3). The project is now under the consideration of the Greek Ministry of Culture for infrastructure and monuments (Ref 1).

Collaboration between the City of Aarhus and private property developer DOMIS Ejendomme has been recognised by the award of a silver certificate for sustainable urban planning for the Bryggervej project. The aim of the project is to try out various sustainability principles. Green and blue solutions are included in the project, e.g. green roofs, green facades, green open spaces and blue elements/water in the park areas to increase recreational values and add moisture to the dry urban air. (Ref. 1, 2, 3)
By 2020, the first residential project was built called Risskov Brynet (Ref 8). Information in the project since 2017 is about this project. The project is certified according to DGNB Gold because it is based on a high standard for both social, economic, and environmental sustainability. An important part of this project is a 'highly insulated climate screen', a technology of the project that is incorporated into the project to address climate change (Ref 8, 9, 10).
