位于尼日利亚拉各斯Ikoyi的金斯威大厦(Kingsway Tower)是一座地标性的建筑综合体,坐落在Alfred Rewane路一个显眼的角落,这条干道将城市一分为二,北至机场,南至维多利亚岛。大厦由南非建筑公司SAOTA设计,高15层,有一个地下室,一座二层零售裙楼,一个停车裙楼和12层的办公楼。金斯威大厦不仅为拉各斯这座尼日利亚的经济中心,同时也是世界上发展最快的城市之一,引入了新的设计理念,并且在建筑质量和执行管理方面体现着这个新兴市场在全球范围内的重要地位。

Kingsway Tower in Ikoyi, Lagos, Nigeria is a landmark mixed-use building set on a prominent corner on Alfred Rewane Road, an arterial road that bisects the city leading north towards the airport and south to the Victoria Island. Designed by South African architects SAOTA, Kingsway Tower is 15 storeys high. It has a basement, a two-level retail podium, a parking podium and 12 office floor levels.

Not only does the design of Kingsway Tower introduce new architectural ideas to Lagos – the economic centre of Nigeria and one of the fastest growing cities in the world – but it is also uncompromisingly world-class in its quality and execution, reflecting the importance of this emerging market in a global context.

Alfred Rewane路位于著名的Ikoyi住宅区,周边地带经过重新规划已经形成了一个多功能区域走廊,也唤起了办公建筑和酒店的蓬勃发展。然而,拉各斯的许多开发项目都具有相当程度的匿名性,它们大都遵循统一模式,采用混凝土板和制式外墙。\"我们希望设计出一栋针对拉各斯独有特点的,能够用外立面回应气候的建筑。\"项目首席建筑师,SAOTA总监Greg Truen如是说。

Located in Ikoyi, a prestigious residential neighbourhood, Alfred Rewane Road and its surrounds have been rezoned to create a mixed-use corridor, resulting in a boom in office and hotel developments. Much of the development in Lagos, however, has a fairly anonymous character, generally following a standard commercial model with concrete slab and curtain wall facades.

“We wanted to design a building that made direct references to the fact that it was in Lagos, with a façade that responded to the local climatic conditions,” says SAOTA Director Greg Truen, lead architect on the project.

The distinctively swollen, billowing form of the tower subtly references the square sails of the traditional boats on Lagos Lagoon while conveying the effect of the gentle breeze that characterises the climatic conditions of the city. The tower rises above a wavy canopy with a “woven” pattern on its underside, reminiscent of fabric caught in the breeze. The canopy sweeps around a two-level retail podium, providing shelter at street level and lifting invitingly towards the entrance at the most prominent corner.

The folded, perforated aluminium screens on the tower’s outer façade are primarily responsible for the building’s iconic identity. SAOTA was, however, careful to avoid direct or literal metaphorical equivalencies. They preferred to abstract the inspiration for its patterning – tropical vegetation, especially palm trees, along the tropical lagoons in and around the city – so that they seem simply “of their place”, appropriate to the climate and economy in their aesthetics, practicalities and performance rather than asserting overt cultural references.

The screens on the outer façade are arranged in multiple layers, creating a porous, permeable façade with depth and a sculptural quality, that, as Truen puts it, casts “interesting shadows internally as the layers shift against each other”.

Unlike typical European and American towers in the modernist tradition, the façade treatment is configured more like a shopfront than a curtain wall. “The slab projects past the glass face,” says Truen. The aluminium screen is positioned at the end of the slab, which not only improves the passive performance of the building by reducing the solar load, but it also allows access around the perimeter for easy cleaning and maintenance.

“The other climatic response was to position the building with the short facades facing east-west, and the long facades north and south,” says Truen. “The sun gets into the sky very quickly in Lagos, so you’re dealing with a heat load that is coming from a fairly vertical angle. The combination of the overhangs, the shading devices and the north-south elevations is very effective.”

弧形顶棚下大量的公共区域使大厦与周边环境连接紧密,并呈现出与街道和人行道之间高度开放的视觉联系,这一点尤其体现在Glover和Alfred Rewane路的突出角落。LED照明不但增强了大厦的夜间开放性,更保证了气派的视觉效果。”激活街角的生命力非常重要,”Truen说。这种观点在拉各斯是罕见的,大多数当地建筑都试图独立于周围的环境,因此仅把空白的墙壁和围栏呈现给街道,几乎不考虑如何提高街景和公共空间的质量。SAOTA希望本次设计所提供的干预措施能够促进打破这一传统观念,同时为周边的城市结构做出积极贡献。

The street level facade below the curved canopy is populated with publicly accessible spaces, tying it meaningfully to its context and presenting a highly open visual connection to the street and sidewalk, particularly on the prominent corner of Glover and Alfred Rewane Roads. At night, LED lighting enhances the impression of openness and accessibility, not to mention its visual impact. “It was important to activate the street corner and give it a presence,” says Truen.

This approach is unusual in Lagos, where most buildings present blank walls and fences to the street, severing them from their surroundings and doing little or nothing to enhance the quality of the streetscape and shared public space around them. SAOTA hopes that this intervention will catalyse positive change while making a contribution to the urban fabric immediately around it.

The interior architecture and design of the lobby picks up on the diagonal grid-like element of the canopy, expressed in the panelling as faceted timber triangular elements folded around a diagonal axis. This sculptural approach and simple patterning, along with the use of readily available materials, allowed for all of the joinery to be sourced and built locally.

The bold cone-shaped canopy over the reception desk has an impact from beyond the building, creating interest from the street outside. Like the façade, the interior lobby treatment renders more detail and interest as you approach it.

The power supply in Lagos is erratic and municipal services such as water and sewage are limited or absent. As a result, in addition to passive energy solutions that significantly reduce the requirement for air-conditioning and providing ample natural lighting, all servicing – water supply and treatment, backup power generation and sewage treatment – is provided on site.

The rapid growth of Lagos, with a population upward of 20-million people and climbing, places unique demands on the city and its architecture. “It’s a place that doesn’t have any time for nostalgia,” says Truen. “It’s constantly renewing itself to cope with the capacity that’s required.”

In this context, Kingsway Tower aims to inaugurate a new design narrative, addressing the city’s unique demands and challenges while reflecting both local and global confidence, an approach affirmed by Kingsway Towers’ first tenant, international computer software and technology company Microsoft.
