Real estate development

Belfast is located within the River Lagan Catchment and is at risk from flash floods caused by storm water unable to drain away into the combined storm and sewerage network. The Local Development Plan will facilitate the development of green infrastructure resource or ecosystem services such as the green wedges in Lagan Valley Regional Park (ref 2). Lagan Canal is one of the emerging partnership projects to produce plans to restore and revitalise the Lagan Canal corridor. The river Lagan and the canal is an asset for the city, and for the wider region (Ref 1).

Grangetown is the site for a flagship environmental programme to tackle flood risk and water waste (ref 5). This scheme catches, cleans and diverts rainwater directly into the River Taff instead of pumping it over 8 kilometres to the sea. It will make Grangetown a greener, cleaner place and enhance local biodiversity (ref 2). Every year more than 40,000m³ of rainwater is diverted from entering the combined sewer network (ref 1). Interventions include planters, swales, bio-retention ponds, permeable paving and curb drainage, making use of the existing streetscape. 108 rain gardens have been created, and 130 trees have been planted; the area has been deemed the 1st "bicycle street" in Wales (ref 8). Wider benefits include education, health, well-being (ref 1).

The Malmo Office Tower is a building of offices built having in mind the example of the Swedish city of Malmo. The building is the only green building in Craiova and it has as a starting point the development of sustainable infrastructure and the use of alternative energy sources. It contains green balconies and it aims to become an example for other cities throughout Romania, bearing as a goal to transform in reality "the dream of a green city, where our children can breathe without worry" (1) It is located near the major 2 parks of the city.

The largest park that Craiova has (third in Europe and second in Romania), the Nicolae Romanescu park is a historical area which includes green space, a hippodrome, a lake and a zoo. In 2015 the park went into rehabilitation with money allocated by the EU (1).

The 40-storey mixed-use skyscraper will serve as an economic catalyst for the French city’s central business district and comprise offices, a hotel, a restaurant, and residences. The tree-covered areas of the tower will give the building its iconic appearance and a portion of that green space will be open to public use (Ref. 1). Trees will line the platform of the building and a ribbon of gardens will curl around the glass facade to its full height (Ref. 2).

The garden was designed by landscapers Michèle Orliac and Miquel Battle and realized for a cost of 3 million euros. This "new green lung", as presented by the City Hall of Toulouse, is part of a major urban project that provides for the creation of 500 housing units in the Niel District (Ref. 1). The project involved creating vegetation enmeshed benches (Ref. 7) and using permeable flooring materials that prevent water loss and reduce the potential of flooding (Ref. 8).

Derelict flats are replaced by an oasis (including flowers and fine art) on the Aysgarth estate, creating a "long-waited community haven". A community garden was officially opened to "create an area of much-needed green space". (Ref. 1) The project aimed to create a garden that the whole community could enjoy. (Ref. 1)

Due to the challenges caused by climate change, Hamburg decided to become greener and developed a comprehensive, pioneering green roof strategy. The strategy aims at creating 100 hectares of new green walls by 2019 by providing grants for building owners for greening roofs and offering them rain water fee reduction owing to the rain water retention of the green roofs. (Reference 1) The financial support offered until the end of 2019 is 3 million EUR. (Reference 2) The services offered by the city in this plan consist of four pillars: promotion (financial incentive), dialogue, regulation, and scientific support. (Reference 7)

With the relocation of the railways between the Hauptbahnhof and Pasing a large area became available for an infill development strategy. The redevelopment of central railway areas of Munich is in line with the city's guidelines for sustainable development (Perspective München) referred to as compact - urban - green. The initiative is aimed at implementing 7500 new flats and creating 15000 new workplaces in total, which are supported by green recreational areas. (Reference 1) The project consists of six separately planned parts, some are already partially finished. (Reference 2) This NBS discusses Birketweg, one of these parts, which is 60 hectares large.

Arcosur is a new residential neighbourhood project approved for construction in 2008 after the hosting of the Zaragoza Expo 2008. In its structure, it seeks to develop a space of 4 500 000 m2 into around 21 000 new homes, and out of which around 1 500 000 m2 will be squares, parks, and other green spaces. These green spaces would connect the neighbourhood and ensure all residents have access to green areas. (Ref. 1)
