Rotated Forms

Project: Troika, Kuala Lumpur

Architects: Foster + Partners, London

The project is a mixed-use scheme that brings together high-quality apartments, offices, shops and restaurants in the centre of Kuala Lumpur. The three interconnected residential towers—of 38, 44 and 50 storeys respectively—together form the tallest residential development in Malaysia. They are the first apartments designed by the architects to be completed in the city. The development is located within Kuala Lumpur City Centre—Kuala Lumpur’s ‘city within a city’—at the north-eastern corner of KLCC Park. The stepped form of the towers responds to the surrounding buildings and is designed to maximise views of the park and the nearby Petronas Towers. Slender concrete walls support a series of stacked residences. The internal planning of the units is subtly rotated, so that the glazed walls and balconies of the main living areas in each of the 230 apartments address the best possible view. The offset arrangement of the sheer walls generates a variety of plan sizes,
and the internal organisation of the apartments is fluid, to allow each to be individually planned.

Where possible, the towers are self-shading, as balconies are sheltered by the overhang of the apartment above. Sky bridges link the towers at level 24 to create a sky lobby with unrivalled views of the fast-changing skyline. At the ground level, a four-story perimeter building contains offices, shops and cafés, with a variety of recreational facilities for residents at its roof level, linked by shaded arcades and accessible throughout the day. The building frames a landscaped courtyard, which is entirely free from cars and provides an urban oasis at the heart of the development. Residents enter via a grand entrance on Jalan Binjai, which leads to lift banks on individual floors, shared by two apartments per floor. David Nelson, senior partner and joint Head of Design at Foster + Partners, commented: “The Troika’s rotated forms evolved through a unique design process, which included a detailed modelling analysis– the towers were literally sculpted to respond to the surrounding buildings and the specifics of the site and local climate. The result is a delicately crafted cluster of towers, centred on a landscaped plaza, that are an elegant addition to this prime location in the heart of Kuala Lumpur.”
