TransformationsOver the years, transformations in urban areas have taken place in varied forms, includingthose pertaining to size of form, landuse, encroachments, structure heights, floor areacoverage in other words illegal constructions etc. This has also occurred in the formaldevelopments of the city very much outside the legal framework. Though, the growth maynot be in accordance with the planning norms of the city, but its very existence highlights itsmagnitude. Some of the key transformations occurring in urban areas in general and Delhi inparticular are summarized in subsequent paragraphs.3.1. Types of Transformations3.1.1. Use affiliationThis is a type of transformation that pertains to extent and nature of non-residential use inresidential areas and of other uses in areas meant for open spaces. This phenomenon is veryevident along the main transport routes and in the developments with smaller plot sizes/dwelling units. In other words it can be stated as invasion of stronger land use over weaker interms of prevailing demand, which is acting as an impetus for growth of a particular land use.For example at several places in Delhi, the residential buildings along the road or streets neara planned market or business areas are converted to commercial spaces, open areas are beingencroached upon for houses, shops etc. The prime reason of this type of transformation ispressure exerted by economic forces, where in the importance of economics prevails over thatof habitation.3.1.2. Built FormThe transformation is in terms of extent of consolidation, horizontal coverage,encroachments, condition of structures, streetscapes. To fulfill there need of space peopletend to increase the covered area of the plot. There are encroachments on the common openspaces or the road to accommodate their things. The dwelling units are converted tocommercial area for retail shops etc. and the residential activity is accommodated on theadditional floor which contributed to the height transformation occurring in the planneddevelopments. This type of informality is seen in formal settlements having very small areasof dwelling units which with passing time becomes difficult to manage with. Social pressureis the main reasons for this type of transformation where an increasing population needs to beaccommodated in the limited planned space.3.1.3. Time AffiliationThis type of transformation pertains to the changes that happen over a period of time. Interms of time relationship, the informal growth may be of temporary nature (which havebecome permanent over time), permanent nature or appearing before its envisaged time. Forexample, increasing area use by periodic markets, roadside petty sales, ‘teh bazari’ getsconverted into permanent markets etc. The permanent nature of informality refers to the7
