London-based architecture firm PLP has revealed plans for a mixed-use complex in China's Pearl River Delta. Nexus is an investigation for 'an alternative to the high-rise point tower typology', explain the architects.

The scheme comprises four different functions; a 600m office and hotel tower within the Nexus Building; the performing arts complex Platform for Contemporary Arts; the 300m-high Lizhi Park office tower; and the Concourse, a large scale retail and leisure facility that brings all the above together in a single sweep.

The team aimed for flexibility and variation in the overall form and function, so this complex is composed of different elements – there's three tall volumes of different heights, ranging from 44 to 124 storeys high. The way the structures are engineered also helps challenge the norm.

'The centre-core high-rise office is one of the most wide-spread and recognisable urban typologies. Yet in spite of this, their interior spaces are increasingly unsuitable for today's collaborative work. Their outer envelopes mask rather than broadcast inner life,' says PLP's Andrei Martin. 'Our Nexus building proposes a different typology where floorplates offer qualities unprecedented for a high-rise. Because there is no central core, everyone can see each other. And because each floorplate is shaped as a bar, there is light on both sides, cross-ventilation, and an overall atmosphere constantly shaped by the environment outside.'

Environmental measures include the buildings' broken down geometry, which is angled according to the area's sun and wind orientation in order to control heat, and a large water element on the base of the complex, which helps cool down the area, lowering the overall temperature.
