Studio Emergence undertakes the design of a metro station, a commercial complex, and a railway station
The design team at Studio Emergence undertake the design of three different projects: a metro staɵon, a commercial complex, and a railway staɵon, with a focus on their aestheɵcs, user-friendliness, and funcɵonality
MMRDA Andheri Metro Design for Line7
The Andheri Station presented several challenges: it is considered a hub for transportation due to the several linkages it provides and its strategic position. Adding a metro station would only add to its high footfall. Since the metro is an elevated system, it is imperative to have a design that merges with the city fabric. Such massive structures need to be treated as positive interventions. The structure of the Metro station is a rational response to a series of programmatic requirements and constraints, and the result is a steel-and-glass canopy. The stunning oculus form creates a new structure that is functional, contemporary, and contextual; a new grand civic space for Mumbai. The structural steel is not only super-strong and durable but can be used in innovative ways, turning the ordinary into something quite transformational, even though the main structural system is mainly of steel. The façade is a parametrically designed jaali with the apertures increasing in size proportional to the distance from a high-rise building next to it and giving privacy to the residents in the vicinity. The result is a rhythmic pattern on the façade, creating dramatic shadows on the platform and concourse level. Wayfinding was integral to the design with unobstructed views across the public spaces, a visual connection to the central circulation spine, and ample outdoor views. The use of exposed structural steel enhances the unique architectural expression and its use, prominent throughout the public areas, and achieves the desired visual quality and texture. Achieving a roof structure reminiscent of a jaali involved use of curved tapered steel plate girders that dynamically intersect in the middle of the structure. The flooring pattern also resonates with the same jaali pattern to allow synergy and continuity in design. The primary structural system consists of (16) steel arch trusses spanning nearly 17m. Though the overall geometry of the metro station is a complex, seemingly free-form series of curves, the realization of this geometry was achieved by using only members curved to one circular radius. This rationalized approach allowed the geometry to be conveyed in simple 2D plans and elevations, without the need for 3D work point
schedules. For the terminal’s central spine, field erection was sequenced to utilize the rigidity of the X-girders to minimize movements and the need for extensive temporary bracing. Additionally, the joints provided improved thermal expansion characteristics for the concourse, which is nearly one quarter of a mile long. Because much of the steel framing was exposed, the design team worked closely to develop details that achieved the architectural vision and were also efficient to fabricate. The fabricators can make extensive use of custom jigs and fixtures to position the members in the shop to minimize welding distortion in the cruciform columns and in the architecturally exposed structural steel curved roof girders.

The apertures, which create the pattern, are a series of open, opaque and transparent panels to enable the station to be well lit and ventilated. The roof panels have been given openings in the polycarbonate sheet so as to ensure the station is naturally lit. The platform level has ample openings to help ventilate the non-air-conditioned space, whereas, the roof will have lesser openings which will enable light but also prohibit excess heat in the Mumbai weather. To keep the design within budget, the exposed connections were engineered to use only conventional structural steel fabrication techniques and materials, and great care was taken to shape the connections to be aesthetically minimal and consistent. All exposed structural steel is painted white/grey with a highperformance coating system consisting of a shopapplied zinc-rich primer and a finish coat.
Seeja Sudhakaran MMRDA had, for the first Ɵme, invited architects from all over India to design the new Metro staɵons coming up in Line 7 in the western suburbs. Aōer the iniɵal site visits, the architects were given a brief on the scope of work. Studio Emergence was shortlisted amongst the top 10 architects and subsequently bagged the project along with another firm.
