Larkhill Gardens Lake improvement is a collaborative project between the City Council, the Environment Agency and the local community. It is part of the long-term project, Liverpool Park Lakes Project, whose aim is to tackle many problems faced by shallow park lakes. Larkhill Gardens Lake (4936m2) a circular shaped, steep, vertical hard-banked lake, situated in a small estates garden in the city. Like many lakes, Larkhill Gardens Lake experienced problems linked to structural decline, lack of water, poor water quality, poor habitat quality, loss of management of the user and lack of proactive management by the City Council. The improvement of the lake included changing its structure to create a deep-water fishing area, shallow water area and wetland.
The project was funded by a partnership between Liverpool City Council and the Environment Agency (Reference 1).

The present intervention is about the rehabilitation of the freedom square (Námestie hraničiarov) (formerly Gottwald square) in the city district of Petržalka of the city of Bratislava (9, 11). The area of the intervention is about 1 ha. The pavement was replaced by grass areas, trees, and flower beds in the square’s alleys. A water capturing and irrigation system was also installed to ensure resilience to drought. The project was implemented by the city district of Petržalka, which is - with 100,000 inhabitants - one of the larger and most densely populated districts of Bratislava. (1)

The intervention was planned to revitalize and clean a derelict area close to the university hospital in Blato. Before the project was implemented, the area was an informal waste disposal site for the locals. The area was neglected for more than 30 years. Initially, Mayor Milan Bandić planned a large urban park with a thermal spa in the spot. The area was cleaned and some of the constructions had begun, but later it stopped due to some political hurdles (Ref 1, 2).
The first phase, cleaning the shrubs and waste from the area has been completed in 2015, but the use of the area has not been determined yet, therefore the project has not been completed (Ref 1).

The rooftop garden of Nádor 15 was implemented as part of the sustainable campus development strategy of the Central European University. It contains a community garden that is managed by the CEU community, intensive green roofs and green walls as well. The rooftop garden also collects water for it's automatic irrigation system and supports biodiversity with bat shelters, bee hotels and birdhouses. (Reference 1)

The project refers to the development of a vacant plot to create a social garden. Activities and plans implemented included: planting greenery, creating flower meadows and flowerbeds, common flowers planting by citizens, common vegetable growing area and a greenhouse, recreational area (hammock, trampolines, field games, sun loungers and sofas for recreation), cultural zone (outdoor cinema, exhibition space), workshop area (for artistic, ecological and sports workshops), canteen area (open-air kitchen, outdoor bar, communal dining space). The garden was open for the public between 2016 and 2018.(1)(4)

In 2013, architecture firm BIG's design was chosen for a proposed Museum of the Human Body in Montpellier (Ref. 1). The plan was "An ambitious scenographic project resulting from a simple and clear spatial design. The alliance of its architectural, environmental, and functional qualities". "The gentle slopes of its roofs transform into a landscape intertwining vegetable and mineral terraces that provide direct access to pedestrians on the urban sidewalk and the park" (Ref. 2). It would have involved a "park of eight hectares" (Ref. 12, page 4). The project has not yet become a reality (as of August 2, 2020).

CityTree is a four-meter high freestanding installation that is able to purify city air of harmful pollutants by using a special moss culture. (Reference 1) The local government of the 3rd district tested the technology under a 6 month trial from September 2017 to March 2018. The CityTree pilot project in Budapest was concluded, once the district administration decided not to continue the project further due to technical reasons. The irrigation system started to malfunction very early in the trial period, which caused the mosses to dry out and thus producing no quantifiable results. (Reference 9)

Developer company Helix plant systems built a facade for the restaurant at the Kasselbrink pavilion located at one of the central squares of Bielefeld. According to the preliminary expectations, the green facade will release 760 kg of oxygen per year and absorb 1070 kg of CO2, having a positive effect on the ecosystem, reduce the building's energy use for heating and cooling while also has aesthetic value by breaking the grey tone of the square (Ref. 1, 7, 8).

The Svoradova small park is an NBS site of the Bratislava zelenaj project. The newly renovated park (once part of the historical Pálffy Garden) on Svoradova Street in Old Town was previously abandoned and neglected. (14) It is part of the citywide Bratislava zelenaj project aimed at protecting and promoting the welfare of the city’s vulnerable citizens from the effects of climate change, (1) providing a safe recreational space for children (with a small playground for playing and swings). The park also has new lighting, and the whole space is home to new flowers, bridges and trees. (10, 12, 18)

Agora Budapest is a large scale urban redevelopment project initiated by private investors. Besides implementing five high-quality office buildings, the investors aim at creating green public spaces the size of 7000 square metres in order to provide a healthy and vivid working environment. The green surface involves green roofs, parks and tree lines, all which will be irrigated using collected rainwater. The solar panels on the roofs of the buildings are also part of the sustainability plans of the investors. (Ref 1. and Ref 4.)
