The first phase of the research saw them studying all types of small houses in the city, including chawls, wadas, and Slum Rehabilitation Authority and MHADA projects. These were compared across criteria ranging from circulation and ventilation space to room for socialising and leisure. “We started looking into the history of building codes in Mumbai, which took us to 1896, where the first codes were formulated during the plague,” he recalls. The exhibition begins with this historic event, exploring how it was instrumental in changing the urban form and geography of Mumbai. The primary motivation at the time was to create better light and ventilation for people within their homes, since data revealed that the plague spread between compact spaces and unsanitary living conditions. “From this origin point, we started following the rules that were populated around it. Coincidentally, in 2018, IIT Bombay and an NGO called Doctors For You studied settlements built by the state, where buildings stood as close as 10 feet apart from each other. Every fifth member in these colonies suffered from tuberculosis or some other respiratory illness. Their report attributed this to the nature of the architecture and lack of lighting and ventilation in the space. In a sense, the byelaws have allowed these structures to be built. This brings us back to square one because the first laws were to improve these conditions, while the current ones enable the spread of disease.”

During his research Padora discovered how distances between buildings were mandated. “The Bombay Improvement Trust [BIT] enforced a law stating that the angle formed between the base of one building and the top of the building next to it should not be more than 63.5 degrees. If the buildings were closer [or if the angle was higher] the homes wouldn’t get enough light and ventilation within. This was replicated from Glasgow, where the angle enforced is 45 degrees because they’re further up from the tropics.”

Padora says they’ve highlighted architectural differences a common citizen would sense and notice. “For example, in Dadar Parsi Colony, there were regulations written, stating [that] a boundary wall can only be solid till four feet, after which it has to be porous. This lets people look out and brings about a sense of safety for someone walking on the street. However, these days, the first few floors of a building comprise parking after which habitation begins. Since no programme opens out into the street, it renders it dead and unsafe. So you’ll sense the difference walking on the streets at night in old neighbourhoods in South Bombay or Dadar Parsi Colony compared to newer developments in Khar or Lokhandwala.”

One of the arguments this research opens is that Mumbai creates the infrastructure it needs. There are certain dwellings that exist here that cannot be explained through development plans, such as night shelter for children created in a space under the foot over-bridge at Marine Lines. It doesn’t show up in any architectural plans, yet it exists because the city needs it. Similarly, in Dadar, a person owns a shop where he sells his wares in the day and has made a home behind the hoarding above it. “Our next step is to study these anomalies to see if they indicate a means to look at development through the lens that isn’t a Western planning model, but instead reactive to what already exists on ground.”

Perhaps, the most symbolic for the common citizen is the last section of the exhibit that displays diagrams of the city in 1896, 2015 and 2050, where a majority of the city has inevitably sunk below sea level due to climate change. While we’ve read about this over the past few years, visually seeing parts of the city, especially your own home, under water makes you pause and think. “Byelaws operate keeping in mind land as you see it today, not what will happen to Mumbai in 2050 because of rising sea levels. With a lot of land submerged, where will the population go? If they have to move, where’s the space to house them? How will that development take place? The byelaws have to consider not just the way the city is today, but [take into account] the scenario 30 to 50 years down the line.”
