Marina One, Singapore

“Marina One”, a highdensity, mixeduse building complex in the heart of Singapore’s new Marina Bay financial district, complements the Urban Redevelopment Authority’s (URA) vision of making Singapore a “City in a Garden”.

Singapore´s new Landmark has recently topped out and will be completed at the beginning of 2017. The highdensity, mixeduse building complex is green in both a literal and performative sense. Flanked by two large urban parks, it comprises two office towers, two residential towers and a retail podium set around lush greenery. While the outer face of the four towers strictly follows the city grid, the maximised inner space is a freeformed threedimensional biodiversity garden. This "Grean Heart" will be the largest public Plaza in the Central Business District. Openings between the highrises, sky gardens inbetween the podium, the elevated towers, as well as the shape itself, improve the air flow and create a comfortable microclimate within the multiple levels of the central garden that covers up to 125% of the site area.

Due to ingenhoven architects´ integral concept of supergreen®, a comprehensive and ambitious architectural approach, Marina One aims to regreen the city. Its office towers meet the “LEED Platinum Precertification” and the local “Green Mark Platinum” standards for their sustainable design. The 30storey towers, each with a floor area of 175,000 sq m, feature two sky gardens and two highdensity floors on levels 28 and 29. The highdensity floors will be the largest “GradeA” office floors in Singapore. The luxurious “Marina One Residences” are housed in the two 34storey towers with 1,042 city residences ranged in size from one to four bedroom units and penthouses. The building footprint is penetrated by air wells and slots to ensure natural ventilation for all of the units, thus meeting the stringent green mark platinum criteria.

In addition to a compact and efficient building layout, the environmentallysmart design also features energysaving ventilation systems, a highly effective external sunshading system and high performance glazing to reduce direct solar radiation into the building. NEWater (centrally provided recycled water) for toilet flushing and a rainwater harvesting system reduce water consumption. PV cells make use of the sun’s energy. Furthermore, the direct connection to four out of the six Singaporean MRT lines and bus stations as well as the provision of bicycle parking spaces and ecar loading lots significantly reduce emissions caused by individual traffic.

A variety of restaurants and cafes, a fitness club, a food court, a large supermarket and event spaces are located on the different public terraces, not only providing all the local resources and services required to serve the residents, office workers and visitors, but also creating a vibrant public destination. This multiple level green heart will be a civic sanctuary larger than any existing public plaza in the CBD of Singapore.
