They have priced-in the mixed development, which is the right thing to do. Only issue is, the mixed development isn't a guaranteed success yet. But assuming it can deliver (the neighborhood mall is bustling, office towers occupied, the hotel has decent business), then yes, I would say it is justified.

Another similarly priced mixed development nearby would be The Millerz, much further up Old Klang Road.

The only property that is way overpriced, since the day it was launched many years back and remains so today is Verve Suites @ KL South. Absurd to be priced at close to RM1k/sqft and it is only a refurbished old building.
