Bombay International School (BIS), Mumbai, designed by Mobile Offices.


The school is housed in a 100-year-old heritage residential building, which has evolved into a child-centred IB (International Baccalaureate) school over a span of fifty years. The design explores the idea of flexible and interactive learning environments. The space planning reflects the liberal pedagogy of an international education adopted by the school, by re-imagining the “traditional classroom model” by ensuring the heritage significance of the structure. A process of delayering and revealing the embedded features of the heritage structure is revived.

The shift is from a traditional classroom-based learning environment to creating subject rooms and shared common programs that offer a varied environment for learning and collaboration between students and teachers. The attempt was to make the existing divisions of classrooms porous, combine common shared spaces and create non-traditional collaborative learning spaces like courtyards, balconies, and chill-out spaces along the circulation.  

Special features

Design as a participatory process

There were workshops conducted by us, with the students, parent committees and teachers to understand their perception of ‘constants and change’ within the school which were extremely interactive and informative. Existing concerns of structure, services, environmental concerns, reusing residential scaled spaces, and retaining the character of a heritage building for accommodating spaces of flexible learning were very important considerations in the design process. 

Vision for learning environments

Earlier fragmented residential programs had to be overlaid with learning environments, which were more porous and flexible.  The need was to accommodate small group learning, outdoor learning, lectures, project-based learning, and distance learning, performance and music-based learning, independent study, one-on-one learning, learning with technology.

The Structure

The walls of the building are constructed out of load-bearing stone. The load-bearing structure disappears on the higher floor as trusses support the lighter roof above enabling large-span spaces for collective programs.  It comprises multipurpose rooms, which are used for performances, sports, yoga, seminars etc.

Original feature Flooring

The original flooring was retained and newer patterns by the use of repetitive motifs observed were designed bringing together the heritage character and a contemporary language.

Walls; certain walls were used as both storage and display within redundant doorways to maximize the use of the floor space. Ceiling; Dual source suspended lighting was designed across the rooms to highlight the rafters and jack arch ceilings to ensure the revival of the heritage value of the structure. Doors and windows; were retained but restored. Old teak was sourced to revive the unique character of the interior and exterior elevations and facades of the building.

The Good, the Bad and the Aesthetic - Bhopal

The Good, the Bad and the Aesthetic

This essay delves into how municipal corporations envision creating Western cities (instead of responding to the Indian context) and end up creating cities that only appear to work, instead of actually being more socially inclusive, dynamic and publicly active. The Smart Cities Mission then caters only to the rich and this becomes evident in not just the visuals they use, but also the manner in which they describe their vision of a World Class Infrastructure. This essay by Avani Mittal is amongst the shortlisted essays.
