<a href="https://www.thenationalnews.com/tags/expo-city-dubai/" target="_blank">Expo City Dubai</a> has offered a first glimpse of two new housing developments promoting sustainable living due to launch this week. Striking renderings of Expo Central's Mangroves Residences and Expo Valley have been unveiled before the opening of a sales centre in the Sustainability District, on Wednesday. The major residential projects are central to the transformation of the sprawling world's fair site into a vibrant neighbourhood of apartments, townhouses and villas, as well as 10km of cycling tracks, a 5km running track, children’s playgrounds and 45,000 square metres of parks and gardens. Expo City Dubai districts are free of cars and single-use plastics. The design has retained 80 per cent of the original infrastructure, including 123 buildings. Approximately one third of the 4.38 square kilometre site has so far been built on. More details of the development are due to be announced this week. Expo chiefs said homes at Expo Valley will overlook a nature reserve, lake and wadi. The area will boast smart, sustainable villas and townhouses and feature car-free lanes, cycling trails, clubhouses and landscaped courtyards. Expo Central's Mangrove Residences will focus on sustainable, urban living and will feature views of the Expo City skyline. It will be home to retail and food and beverage outlets and aims to promote an "eco-friendly lifestyle". Ahmed Al Khatib, chief development and delivery officer, said the city “will serve as a blueprint for the way we live in the future — a best-in-class example of sustainable, regenerative, connected community living”. The current residential offering in the area is Expo Village which has 2,273 flats in 15 towers and accommodates about 3,500 residents. The development is owned and managed by Dubai World Trade Centre. Before the world's fair closed last year, Expo 2020 announced plans to transform the legacy site into the country's <a href="https://www.thenationalnews.com/uae/expo-2020/2022/02/03/expo-2020-dubai-legacy-site-to-become-uaes-first-15-minute-city/" target="_blank">first “15-minute city”</a>, meaning it will be possible to walk or cycle from end to end without the need of a car. In June, Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai, <a href="https://www.thenationalnews.com/uae/expo-2020/2022/06/20/ruler-of-dubai-unveils-expo-city/" target="_blank">set out his vision for the legacy site</a>, saying it would become a “hub of economic activity” and home to major companies and their headquarters. With a focus on technology and the environment, he said it will serve as a destination in its own right, served by the nearby Dubai World Central airport and the metro link to the city centre. The city started to open up in phases in October, with its key attractions remaining in place, including the Al Wasl Dome, the Garden in the Sky observation tower and the Expo waterfall. It also reopened Alif, the Mobility Pavilion, Terra, the Sustainability Pavilion, as well as the Vision and Women’s pavilions, which visitors can access with a Dh120 day pass. Businesses have also started to relocate to Expo City. <a href="https://www.thenationalnews.com/uae/2022/05/13/germanys-siemens-to-move-hundreds-of-staff-to-expo-2020-dubai-legacy-site/">Siemens</a>, DP World and China’s Terminus Technologies have taken offices in the Dubai South neighbourhood, alongside start-ups and other technology companies. Dubai Exhibition Centre, adjacent to the metro station, is a venue for major events such as international trade fairs. It recently hosted PopCon Middle East and GameExpo in Dubai and later this year will be part of the emirate's hosting of the <a href="https://www.thenationalnews.com/tags/cop28/" target="_blank">Cop28 Climate Change conference</a>.
