I know a project in Jalahalli. They quoted Rs 00 for a bulk purchase
of 50 sites.
The cost in HRBR ranges between 7100 (1st block )to 7500 ( ring road
facing plots ). In kalyan Nagar / Hennur, you should get it for 4500
psft.
A villa on a 50X80 plot can cost upto 4 Crores in HRBR. In
kasturinagar, just before ram murthy nagar, a normal house 3000 sq ft
on a 30x40 can cost upto 1.6 Crores.
Hope this Helps
