这座前UIC大楼位于新加坡中央商务区的中心地带，自1973年建成以来一直作为新加坡的最高建筑，并成为珊顿大道重要的塔楼之一。最近，该地区经历了一次复兴和改造，而新UIC建筑V on Shenton成为这次重建的一部分，同时该综合体是区内独有的。
‘V on Shenton’的双塔由23层高的办公楼和53层高的住宅楼组成，其体量也可反映其建筑的双重用途。 办公大楼响应周围建筑物的规模和街道，而住宅大楼则被设计得更高耸以区别于邻近的建筑物。 沿着空中大厅向上攀登，住宅大楼的单元组合随之改变，低调地展示其分裂核心。 这种分离状态同时表现塔楼的自然通风概念，并通过核芯旁的通风槽进一步实现效能。 V on Shenton的独特设计，这些通风槽由外立面覆层覆盖，带有开口使空气流通，在住宅大楼上形成连续、不间断的六边形立面图案。
每个塔楼都由 “倒角” 框架，这是一条连结住宅楼、办公楼和底座的线。在白天，倒角看起来平滑，与塔楼的纹理表面形成对比。在晚上，倒角照亮了塔楼、停车场和空中花园，形成连续线条。办公大楼北端的倒角也形成开口，饱览滨海湾、武吉知马山和中央商务区的景色。
Singapore is currently one of the most densely populated countries in the world. Although land reclamation has boosted the island’s size over the years, Singapore still faces significant density challenges.
Vertical expansion has for some time proved to be a solution for the efficient use of valuable urban land. However, it has recently become clear that such expansion can be further maximised through the introduction of large scale, holistic, mixed-use developments that offer round-the-clock programmes. In these developments working, living and leisure activities are catered for within single plots, ensuring maximal use of scarce land.
Located in the heart of Singapore’s Central Business District, the former UIC Building dominated the city skyline as Singapore’s tallest building for many years following its completion in 1973 and formed part of an important collection of towers located along Shenton Way. Recently the area has undergone a rejuvenation and transformation and V on Shenton – the new UIC building – forms part of this redevelopment. The mixed-use programming of V on Shenton presents a unique situation in this area of the city.
A response to context
The twin tower of ‘V on Shenton’ is comprised of a 23-storey office building and a 53-storey residential tower, with the dual programming of the building is highlighted through its massing.?The office tower responds to the scale of the surrounding buildings and to the street, while the residential tower rises up to distinguish itself from the neighbouring buildings. Above the upper sky lobby the unit mix of the residential tower changes with a subtle display of its split core. This separation also exhibits the natural ventilation concept of the tower which is further effected through ventilation slots next to the cores. Distinctive to V on Shenton, these slots are covered by facade cladding with openings for air circulation, resulting in a continuous, uninterrupted hexagonal facade pattern on the residential tower.
In addition to the office and residential programmes, the dual tower building houses a number of fully integrated sky gardens which provide panoramic 360 degree views of Singapore and house a variety of amenities – such as a fitness area, swimming pools and a children’s play area, with lush green vegetation providing fresher, cleaner air. These areas provide spaces for shared communal activities, or for the residents to entertain guests.
The most ample and diverse of the three sky gardens covers the entire 8th storey of the development. At the two sky lobbies in the heart of the residential tower, residents are given even greater privacy, combined with views of the city or the ocean from both the 24th and the 34th floors. The residents of the penthouse levels also have exclusive access to the outdoor roof terraces on the 53rd and 54th storeys.
On the ground floor of the development stainless steel lines are inlaid into the floor, lines of light in the ceilings emphasise common areas, vertical lamellas clad the car ramps and together these form the guiding principles for pedestrians to their destination.?On ground level, next to the office tower lobby, a large café forms the central meeting point for the public areas.
A family of patterns
Just as the office and residential towers are of the same family of forms, so do their facades originate from the same family of patterns. The basic shape of the hexagon is used to create patterns that increase the performance of the facades with angles and shading devices that are responsive to the climatic conditions of Singapore.
The office tower is based on a curtain wall module and an optimised number of panel types, recombined to create a signature pattern. In contrast, the residential facade is based on the stacks of unit types. The pattern of the residential facade is created by the incorporation of the residential programme (balcony, bay window, planter and a/c ledge) and the combination of one and two storey high modules with systematic material variations. These geometric panels add texture and cohesion to the building, whilst reflecting light and pocketing shade. The texture and volume of the facade are important to maintaining the comfort of those living and working in the residential and office buildings. Shading devices and high-performance glass are important for developing a sustainable and liveable facade.
Each tower is framed by ‘chamfers’; a line that unifies the composition of the residential tower, the office tower and the plinth. During daytime the chamfer appears smooth in contrast to the textured surfaces of the towers. At night the chamfer lights up as a continuous line framing the towers, car park and sky gardens. The chamfers at the North end of the office tower also open up the corners to views of Marina Bay, Buket Timah Hill and the Central Business District.
