'Hanoi Lotus' in Vietnam by Decibel Architecture

Located in the Western district of Vietnam’s capital, the Hanoi Lotus by Decibel Architecture will become the newest cultural epicentre of an area with rapid urban growth. Positioned along one of Hanoi’s main arterial roads that connect the city with Noi Bai Airport it will be a gateway project that will provide a memorable sense of arrival into the city for locals and visitors alike. As per the request of the City of Hanoi, the Hanoi Lotus building will sit atop a lake which will act part of the city’s stormwater control system. The Hanoi Lotus Building will rise out of this 19ha lake as a symbol of growth and prosperity for the bustling city of Hanoi.

The Lotus Building owes it’s form to a pentagonal grid system. The pentagon has been chosen as a metaphor representing the five points of an out-stretched person (head, arms and legs). Ratios of five are also common in nature especially in the organisation of petals structures including the lotus flower.  This brings a nature and human focus to the ordering of the site.The grid is a pentagonal pattern with the Lotus Building as its central node. This allows it to expand across the site in a non-linear manner. This approach  provides flexibility to the design as based on this central node point the grid can be scaled up or down at any point in the design process without effecting the organisational principles of the site.

The ceiling to the main circulation space takes its inspiration from the colours and patterns of the underside of the lotus leaf. It has a sculpted form which blends into the central auditorium volume and consists of an intricate filigree of coloured skylights and light boxes. The dappled light created by this feature ceiling will create the experience of being under the lotus leaves. As one of the most striking features in the Lotus Building it will form  one of the main way finding devices guiding guests from the main foyer around to the lakeside foyer and auditorium entrance.

The petals employ a process of bio-mimicry of the lotus flower, the lotus’ natural structures have formed the framework for our structure. Each layer has been meticulously crafted and forms a complex culmination of fins, glazing, shells and support structure.As well as acting as the Hanoi Lotus’ facade, the petals provide shading to the restaurant and VIP areas, an internal tensegrity structure creating the support system and armature for the complex lighting feature.
