Gram Panchayat is a local revenue authority where as DTCP HMDA will come under town planning agencies. Gram Panchayat is a governing body which manages panchayat limits.town planning agencies are responsible to develop and update master plans. Town planning agencies have exclusive control over specified areas. for example if certain village is under control of HMDA, then DTCP authorities have no right to verify any work related to that village. similarly if certain village falls under the control of DTCP, then DTCP has no right to handle any matter related to that village. .
As the time passes town planning agencies will update master plans and bring more areas in residential zone. If the land is in agricultural zone and if anyone want to construct on that land or do layout, then they need to apply for conversion (from agriculture to non agriculture ) to planning agencies by paying conversion fees. Once the conversion is done survey numbers are marked ?residential under master plan? .
GP Layout : when a layout is made in agriculture land without conversion from agriculture to residential zone in revenue records you can call it as Gram Panchayat Layout. In case if anyone want to construct on that land first they need to apply for conversion then only they will get permissions from local authority for construction. .
Agri farm plots : farm plots will be sold as agri farm plots for which there is no conversion is required. since no conversion is required for farm plots as of now approval for town planning agencies are not required. .
* One can go for construction of farm house in farm plot as per prevailing regulations. .
