Dr Patil assembled his own construction team to work on the project, alongside a number of local craftspeople. For over a decade the team refined manufacturing and construction techniques by mocking-up components of the building on, and in close proximity to, the site. This iterative and experimental process allowed the design team to constantly refine their ideas during construction through continuous prototyping. As a result, the design of the building and its components developed and changed over several years, generating a solution that greatly improved on the initial proposals.

The new building has been designed to minimise the environmental impact associated with water and energy use, material choices and operation. The extensive use of shading minimises the energy used in mechanical cooling and the building’s envelope allows in daylight while controlling glare. Wind tower assisted ventilation cools the key spaces, including the auditorium and concourse areas. Ultra-low water consumption is also implemented across the project. The programmatic elements of the School of Business are grouped around communal covered courtyards and carefully orientated to optimise natural daylight and space on the triangular site.

The grand entrance canopy is four storeys high, with a glass roof that casts multi-coloured shadows across the building’s façade. An open plan reception area, exhibition space, café and informal workspace encourage social interactions between students. At the heart of the building, four large auditoria are arranged around a sunken amphitheatre for graduation ceremonies, performances and sporting events. The auditoria have been flexibly designed to be opened up or closed down, depending on the scale of the event.

The library promotes the exchange of ideas and knowledge across four floors of the building. A sequence of tiers, balconies and stairs create a dramatic internal environment. The scheme incorporates a palette of high-quality materials, including travertine, timber, glass reinforced concrete, aluminium and sealed concrete. Ground-granulated blast-furnace slag, or GGBS, has been added to the concrete mix in lieu of some cement, resulting in a paler concrete with a lower embodied carbon footprint. State-of-the-art furniture, designed by Foster + Partners’ own industrial design team, aids comfortable and efficient study.

The first four storeys of the building house the academic activities of the school and the five upper levels provide residential accommodation for students and faculty members. This change in function is articulated through the cladding, which is robust and solid in appearance towards the base, visually grounding the faculty levels. Four different types of panels have been developed to clad the canteen, library, lecture theatres and administrative offices. Concrete was cast around Perspex and wooden moulds to create perforated GRC screens which push light deeper into the façade, while shading the front part of the building.

In contrast, the upper residential units are clad in lightweight cast and extruded aluminium. The corridors are naturally ventilated and offer glimpses of the spectacular two-acre sky garden which spans the full length of the building, between the academic and residential volumes.
