Purely residential locatlity, temples, churches, shops,fish market, P.bunk, 2 banks etc for all living needs in a KM. CMDA approval and less power cut < 1 hr.
Limited Population growth hope it continues, due to height restrictions & river boundary.
Less pollution air, water & noise (Flight noise literally equal to guindy - from my exp)
Centralised location 15 to 20 kms to many ends of chennai in all directions - Mountroad, Adyar, OMR, Sriperumpudur, Avadi, poonamallee, Guduvancherry.
<4kms for connectivity train,Air,Metro (Upcoming), GOK - Mono in pammal ?
Economical price comparatively lower to other areas & good opps for Middle class.
-ves No drainage facility,Not corporation limit, Connectivity road to porur, DLF manapakam is poor < 7kms. Fear of 2006 plan of Airport expansion
Note : its a personal view point & to my limited knowledge.
To demonstrate how Pozhichalur is value for money, I've picked up some areas in Chennai suburb where 1Gr land is available for 30Lakhs.
Following are the areas I've selected:
1.Sankarapuram, Sithalapakkam - Distance from Madya Kailash 20KM
2.Erumaiyur (Tambaram Kundrathur road) - Distance from Madya Kailash 27KM
3.Padappai (Tambaram Oragadam road) - Distance from Madya Kailash 32KM
4.Pozhichalur - Distance from Madya Kailash 16KM
I measured the distance using iphone "map" app and picked the shortest route.
Of course each of the above areas have their own USP, For eg, Sankarapuram is close to Siruseri, Erumaiyur is close to ORR and Padappai is close to Oragadam SIPCOT. Still IMO, the greatest USP of all is proximity to various places within core city.
Had I selected Teynampet or Koyambedu or Central station as reference point to measure distance, the difference will be much more acute.
I don't know current rate for Erumaiyur, but around June-July 2012, asking rate was close to 900-1200 psf. I'm referring to CMDA and DTCP approved plots. It can't be cheaper than that now, must be atleast 1500-2000 psf.
