IKEA opened its doors in Budapest in 1990. This was the very first store in Hungary. Twelve years later, the store announced that it would install a green roof. The main purpose of the green roof was to compensate the locals for the loss of green space. The green roof was intended to create a biologically active surface that fits in aesthetically into the suburban landscape and provide a home for animals such as pollinators. The green roof, built in 2002, was covered with a Sedum carpet. In 2014, when the original Sedum vegetation died out, the green roof was completely removed. Then, during the autumn 2014 planting, four types of Sedum shoots were seeded. This was followed in the spring of 2015 by the seeding of herbaceous dicots seed mixes, which contained seeds of roughly 50 plant species. The vegetation is regularly monitored by ecologists: in 2021, more than 160 different taxa were recorded, including spontaneously occurring species. The green roof is closed, not accessible to the public, however tours are occasionally organized for professionals [3] [6] [8] [9] [10] [11].

Sky Park One Islamabad is an innovative high-rise apartment building project, located in the heart of the prestigious Gulberg Greens in Islamabad (2). The building has been designed with a unique concept that features a rooftop level garden with ample plantation. It aims to enhance the quality of life for the residents and provide them with facilities for relaxation within the apartment building (3). The rooftop garden spans an area of 9 Kanals (about 650sq.m) and features 7 green courtyards in the building. The 152 residential apartments are all connected to the joint courtyards (2, 3). Rooftop garden are still very rare in Pakistan (5) and as such, the project provides an example for the green vertical housing in Pakistan with a focus on energy efficiency (1).

Jin wellbeing is a senior-oriented lifestyle complex in Bangkok, Thailand, which comprises residences, commercial units and hospitals. The first phase of the development has been completed in 2020. This phase included five residential buildings with senior hospitals, wellness centres and green spaces that cover over 40% of the site. The project aims to create a sustainable living environment while enhancing both the physical and mental health of the people through nature with the “Community of Revine Forest” concept. The main interventions include an urban forest, a therapeutic garden, a community farm, an outdoor exercise area, and a multipurpose area. Ecologically sustainable design has been integrated into the planting strategies and water management to create a resilient ecosystem, mitigate flood and improve water retention capabilities of the area for irrigation purposes.

Iloilo River Esplanade is a promenade and linear park along the Iloilo River, created as part of the Iloilo River Rehabilitation Project. It is the largest linear park in the Philippines and was designed by the landscape architect Paulo Alcazaren. The esplanade is one of a kind in the country that aims to foster biodiversity, store carbon by mangroves and provide protection from possible flood damages. Furthermore, the project aspires to build a lifestyle hub for the locals and promotes educational eco-tourism. The site was an existing dike road devoid of shade and originally built just as a flood control measure. The redesign has showcased its effect on public amenities, received several recognitions and has become a magnet for tourists in this city. [1, 3, 6, 7]

The Sustainable Residential Complex project was a measure taken by the city of Dubai, one of the largest city ecological footprints, with a goal to reduce it to the smallest ecological footprint by 2050. For the past two decades, the UAE government has made an effort to lower its own dependency on fossil fuels, shifting toward more environmentally-friendly sources to power its cities. The sustainable residential complex development project is one of the few initiatives taken by the city administration of Dubai under Vision 2021. Located just outside Dubai the area is the first operational net-zero energy residential complex in Dubai. [1, 2]

In 2018, a new annexe building to the Parliament of Victoria was built to host the increased number of municipal employees. The new building is located in the heritage garden that surrounds the parliament precinct of which one hundred per cent of the footprint has been crowned with two new flourishing rooftop gardens that merge the building into its extraordinary landscape setting (1). The new garden is one of the biggest rooftop gardens in Melbourne and accommodates 300 mostly native plant species that characterise the Australian meadows with wildflowers, grasses and shrubs (2). During the construction of the annexe building and the landscaping of the rooftop garden and the connected sunken courtyard key elements of the heritage garden were protected as touchstones for example a Federal Oak planted in 1890, a Norfolk Island Pine and a camphor laurel ( 7). The garden encourages greater biodiversity within the dense urban context, provides thermal insulation to the new building and creates social spaces for events, announcements and contemplation (2).

The Urban Forest Fund (UFF) was launched in May 2017 by the City of Melbourne to provide financial support to new greening projects that otherwise would not be able to be funded. Such projects include green spaces, tree planting, vertical greening or green roofs on private land" (1 p20). The City of Melbourne has multiple strategies and programs in place to increase the quantity and quality of green space in the city. The UFF aims to support such sustainability lead initiatives by providing match-funding grants to green projects in the private realm. The UFF is a key initiative in tackling sustainability challenges in the entire city, as 75% of its land is privately owned (1)

Parc Marianne is an ecodistrict that aims to address multiple challenges such as climate action for adaptation, environmental quality, flooding, and in response to the high population growth in Montpellier. Parc Marianne is connected to public transportation, has bicycle lanes and car parks, and the sidewalk is shared between pedestrians and bicyclists and structured with trees and other greenery. The park was certified with the ecodistrict label in 2015 following requirements like environmental sustainability, thermal performance, quality of life, nature and biodiversity, and mobility (Ref. 1). Parc Marianne is a mixed neighbourhood with an ability to combine city and nature, quality of life and centrality (Ref. 2).

Revitalization of a large urban park in the Walle and Gröpelingen districts of Bremen. The current park constitutes a neglected area of the former port and shipyards sites with around 4,000 small garden parcels.The local government consulted with numerous societal actors the envisioned project, which aims at the revitalization of the park's both green and blue infrastructure. The goal of the intervention is to create a large recreational park for the districts of Walle and Gröpelingen, which will improve the image of the districts, help with their economic revitalization and provide sustainable practices for urban green care and community gardening (Ref. 2, 3). "Between September 2017 and September 2020, the Green West of Bremen was the focus of the federally funded project "Green Urban Labs" (Ref. 5). As of 2020, "Several of these building blocks have already been started or implemented and have led to an improvement in the cooperation between the actors on site, to an upgrading of the infrastructure and biotopes as well as to an increase in the popularity of the previously rather unknown area" (Ref. 5).

A private investment project that aimed to create a new building complex in the Findorff district of Bremen and build two large residential buildings "Münchner Bogen" and "Findorffer Tor" with green roofs on top. The green roofing of the buildings was influenced by the local actors - the alliance "Green Bremen" and the advisory board of the Findorff Council. The initiative aimed to contribute to sustainable urban development by the positive impact on biodiversity, rainwater retention, improved local air quality and provision of natural thermoregulation for the buildings (Ref. 1, 2, 3).
