Marina One is a high-density, mixed-use building complex with a “Green Heart”. Located right at the centre of Singapore’s new Marina Bay financial district, the scheme is intended to “regreen the city” of Singapore, according to German architecture firm Ingenhoven who designed it. The building has recently topped out ahead of its completion date scheduled for early 2017.
Flanked by two large urban parks, the development comprises two office towers, two residential towers and a retail podium. The project’s most outstanding feature is its “Green Heart”, a central garden among the towers which is expected to be the largest public plaza in the Central Business District of Singapore.
Marina One is green both in a literal and figurative sense. While the towers’ outer face strictly follows the city grid, the inner space forms a three-dimensional void, where the multi level biodiversity garden will be planted. Openings between the high-rises, as well as the shape of the structure itself, improve air flow and create a comfortable internal microclimate.
The two 30-storey office towers meet the “LEED Platinum Pre-certification” and the local “Green Mark Platinum” standards for their sustainable design. Both of them feature sky gardens and high-density occupancy floors on levels 28 and 29, which will be the largest “Grade-A” office floors in Singapore, according to Ingenhoven. Each tower has a floor area of 175,000 sq m.
The other two 34-storey towers house 1,042 luxury residences, ranging 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 units.
The building complex also features energy-saving ventilation systems, an external sun-shading system, and high performance glazing to reduce direct solar radiation into the building. Centrally provided recycled water – used for toilet flushing – and a rainwater harvesting system contribute to reduce water consumption, while photovoltaic cells make use of the sun’s energy.
Direct connections to four out of the six Singaporean MRT lines and bus stations, as well as the provision of bicycle parking spaces and e-car loading lots, significantly reduce emissions caused by car traffic.
Restaurants and cafes, a fitness club, a food court, a large supermarket and event spaces located on the different public terraces, will be available not only for residents and office workers, but also for visitors, thus creating a vibrant public destination.
