If you calculate by the basic construction cost (if you are from Development/Construction Industry)

Persqft is approximately RM200-RM250 (Put it at RM250 due to the quality of Eco World)

2400 sqft x RM250 = RM600,000 (Construction Cost)

1400 sqft x RM100 (Land Cost) = RM140,000 (Land Cost)

Total RM740,000 (Costing Only)

You can't blame the upper-end people from Penang/Mainland, when they have excessive money, they just want to put it somewhere solid.

And the project just gotten the CCC this year only.
