The New Transit Camp in Dharavi provides specific conditions as it has planned, fixed, parcelling of the land. This is rather unique in Dharavi. The plots are about 10 by 20 feet. The long side of a plot is to the adjacent plot. The short 10 feet side is open to an alley.

As a result, the main direction of incremental development is vertical here. Horizontal extension is only possible on the first floor. A cantilever over the alley is common practice. Stairs are put outside of the ground floor, in the alley, with access to the first floor through a floor hatch. The image is almost like the stacking of containers, due to the fixed dimensions of the property. Roof shapes are often pitched, as that is the economic way of draining the roof towards the alleys. Due to incremental development, the alleys tend to be fully built over.
