Actually Ecoworld is a developer, not a contractor. Quality of house depends hugely on the contractor, while the developer does the project coordination work & conceptual planning. Not many pple know this, but this is a fact. I repeat again, the quality of the house depends almost entirely on the quality of the chosen main con. In SG for example, some main cons are renowned for their built quality, and the developers would flock to them for atas projects.
Why was Setia Tropika or Bukit Indah house quality bad last time, compared to their KL projects? It was due to the quality of the chosen contractors, though it's true that Setia's project mgt team could have scrutinised the project more thoroughly back then.
