Ugile said blacklisting means builders will not get any further civic projects and even their ongoing projects will suffer.

Welcoming the step, Sanjeevani Pandey, a civic activist, said many builders confuse consumers with construction jargons and extract more money from them. “Carpet area, built-up area, super built-up area — for an ordinary buyer, all of this becomes difficult to understand. They have little choice but to pay up as they are in a rush to buy a dream house.”

On the amenities front, Pandey pointed out that there was no uniformity on the amount charged by builders. “Different builders demand different amounts for club house, gardens, swimming pools. The amount should be reasonable and proportionate. The civic body should monitor this aspect and publicise it on its website.”

The PCMC chief said suggestions from citizens will be incorporated on its website. “The citizens should themselves cross-check facts before buying the flats. It is a direct deal between the builders and them.”
