Urban Design and Development

A growing share of urban trips now begins with a question typed into a phone. Navigation apps choose routes, and recommendation engines decide which cafés, temples, markets and viewpoints appear first. This article examines how far those systems may be shaping movement in cities, a question long treated as a matter of street geometry and human purpose. It draws on space syntax, the new science of cities, critical work on data-driven urbanism and studies of routing and recommendation. It argues that algorithms should inform spatial decisions without determining human choices, and it sets out five dimensions that Indian planning could use when thinking about movement to 2046. Introduction: a new author of movement Urban design has traditionally asked how the form of streets and spaces shapes the way people move. A newer question sits beside it: as digital platforms such as Google Maps, Apple Maps and Waze, together with the recommendation engines built into travel and food apps, becom...

Abstract Extreme heat has become one of the most consequential hazards for city dwellers, yet urban design responses remain fragmented between tree-planting campaigns, reflective materials and building codes. This article reviews a small, purposively selected body of peer-reviewed evidence on the urban heat island and on design-based cooling, and asks which levers lie within the reach of the street and the block. The review suggests that the most robust cooling at pedestrian level comes from continuous tree canopy combined with reduced impervious cover, that the effect depends on scale and threshold, and that reflective and green roofs act mainly at roof level. Health impact modelling for European cities indicates that raising canopy cover could avert a substantial share of heat-related deaths. The article argues that shade should be planned as public infrastructure rather than as ornament, and outlines implications for Indian streets, where heat, informality and limited footpath widt...

Abstract Form-based codes regulate the physical form of buildings and their relation to the street, rather than land use and density alone. They emerged from New Urbanist practice in the United States and have since been adopted by cities such as Miami. Indian cities have not adopted form-based codes as such, but several instruments point the same way: transit-oriented development (TOD) zones, Gujarat's town planning schemes and design controls in planned capitals. This article compares these traditions through a short review of peer-reviewed literature and official instruments. The evidence suggests that form-based codes can produce more walkable street environments on paper, but outcome studies remain few and mostly American. The article argues that India is better served by a hybrid: a thin form-based layer, limited to street-facing rules, attached to existing land-readjustment and TOD tools, rather than a wholesale imported code. Keywords: form-based codes; comparative plan...

Most Indian bus stops are treated as street furniture: a pole, a sign and, if riders are lucky, a shelter set down on whatever footpath is left. Yet the stop is where the bus network meets the street, and where people stand, often in heat, crowds or darkness, for several minutes a day. This article reviews research on waiting, safety and access at stops, together with recent audits from Delhi and Chennai. It argues that the bus stop should be designed and appraised as a small public room, and proposes a five-part field diagnostic, STOP-5, for designers, ward engineers and transport agencies. Why the bus stop deserves attention now Indian cities are investing in buses again, through new electric fleets, route rationalisation and metro feeder services. Most of the effort goes to vehicles, depots and fares. The place where a rider actually meets the system, the stop on the street, is usually left to a standard shelter drawing and whatever space remains between the carriageway and the co...

Walk down almost any new residential street in an Indian city and the pattern repeats: a two-metre compound wall, a gate, a row of parked cars under a building lifted on stilts, and upper floors that step back as they rise. None of this was designed by anyone in particular. It is what a set of numbers produces when it is applied plot by plot. This article follows one ordinary plot through the rules that shape it, shows how floor area ratio, setbacks, ground coverage and parking minimums each leave a mark on the street, and sets out what a form-based code would ask instead. It argues that the street is the missing unit in Indian development control. Introduction: the architect nobody hired Every Indian street has an author who never visits it. That author is the building bye-law, the set of plot-level rules that a municipal authority applies when it sanctions a building plan. An earlier article on this blog argued, at the level of the system, that Indian cities need a form-based laye...

Many Indian streets that are crowded at noon fall quiet soon after the main shops pull down their shutters. The usual response is more and brighter poles. This article examines why a street that works by day can fail at night, drawing on research on street lighting and crime, women's safety audits in Indian cities and laboratory work on how pedestrians read one another after dark. It argues that the night-time street is a question of urban form as much as illumination, and proposes a five-part field diagnostic, NIGHT-5, that ward engineers, designers and community audits can apply on foot. Why the street after dark matters now For many urban Indians the working day does not end at sunset. Shift workers, students, domestic workers, nurses and shop staff walk home and wait for buses well after 9 pm. Yet a familiar pattern repeats across cities: a market street that is dense with people, signs and goods in the afternoon becomes a corridor of shutters by night, with light concentrate...

Across Indian metros, the podium–tower has become the default for large plots: parking and amenities stacked into a plate, residences or offices lifted above. Residents often gain a safer, greener deck. The street below frequently loses active frontage, continuous walking and human-scale enclosure. Drawing on walkability research, national building guidance and urban-design street literature, this article argues that a podium should be appraised at the kerb as well as on the deck, and offers a five-part field diagnostic for the street interface. Why the podium matters now Large Indian plots increasingly host a single morphological type: a multi-storey podium plate carrying parking, services and sometimes amenity gardens, with one or more slender towers above. Marketing language celebrates the vehicle-free podium as a community amenity. At street level, the same plate often presents long blank walls, vehicle ramps, exhaust shafts and setback leftovers that peel pedestrians away from t...

Two neighbourhoods can hold the same buildings and still produce very different daily lives. What changes is the block: how far apart the streets are, whether buildings hold the street edge, where the public street ends and private ground begins, and whether several uses share one structure. This article compares eight block types on four measures, reads four Indian fabrics from OpenStreetMap at one scale, and argues that Indian plot-by-plot setback rules and gated layouts are quietly choosing block form, and with it behaviour, by default. Introduction: the block as a behavioural system Urban design debates in India usually start with the building (its height, its floor area ratio, its facade) or with the road (its width and its traffic). The unit in between, the block, gets far less attention. Yet the block decides how often a walker meets a corner, whether the building edge makes a street or a compound wall, and how many steps lie between a front door and a shop. This post builds o...
