Quick Recap

Units Specific to South India

Units used in Tamil Nadu Hill Station Real Estate
If you have interested to buy independent house, villa, apartment, commercial building or farm house in Ooty, Kodaikanal, Coonoor, Kotagiri, Gudalur, Yercaud, Yelagiri, Valparai, Kolli hills, Courtallam, Sirumalai, Manjolai and Top slip, Square feet is the unit predominantly used. Though ground is a terminology popularly used in cities like Chennai and in plains, they are not at all used in hill stations.
Whereas if you want to buy residential plots, commercial land in Ooty, Kodaikanal, Coonoor, Kotagiri, Gudalur, rest of Nilgiris, other Tamil Nadu hill stations in western and eastern ghat, they are defined in square feet or cents normally.
Similarly if you want to buy farm land, estate in Ooty, Kodaikanal and other TN hill stations, smaller piece of lands are specified in cents, acre and bigger estates are mentioned in acre and hectare. Hills & Wills is an online property-advertising platform dedicated exclusively to hill-station properties across India. Its hill-specific listing features enable advertisers to specify the advertised land extent and other relevant property particulars, while allowing interested users to search, view and compare the advertised information and connect directly with advertisers.
Measuring land on flat terrain in the plains is generally easier, whereas measurement in hill stations may be more complex because of uneven, sloping and rocky terrain. The measurement techniques used for hill-station land may therefore differ. If you intend to buy hill-station land, you should independently verify its measurements through an appropriately qualified surveyor or other authorised professional because the measured extent is directly related to the purchase price. Measuring a building generally does not involve the same terrain-related complications and may be similar to measurement in the plains.
