Builder floors in Nangal Dewat: what to understand first
Nangal Dewat sits beside Vasant Kunj, close to the airport corridor, and is one of South Delhi's notified urban villages. That status matters more here than in a regular colony, because the land and building rules that apply are not the same as those in a planned residential area.
Where the paperwork carries more weight than usual
Establish the property's land status and how it is recorded before anything else. In an urban village this is the single thing that determines what can be built, sold and registered.
Check whether the building works were sanctioned under the applicable urban village rules, and confirm the chain of ownership — including any succession or partition history, which is common in village-descended land.
Then get the registry position confirmed rather than assumed. This is the area where assumptions cost the most.
