India demolishes luxury high-rises for violating environmental norms

Two luxury waterfront high-rises in southern India were reduced to rubble in controlled explosions on Saturday in a rare example of authorities getting tough on builders who break environmental rules.

The 19-floor H2O Holy Faith complex of 90 flats — overlooking Kerala state's famous lush backwaters — was the first to go down, collapsing in just a matter of few seconds.

A thick grey cloud of dust and debris cascaded down after officials detonated explosives drilled into the walls of the building, which had been occupied for several years until the Supreme Court ruled last May that it was constructed in violation of coastal regulations.

Minutes later, the twin towers of Alfa Serene tumbled down with an ear-splitting noise. The remaining two complexes will be razed on Sunday.

A crowd of onlookers who flocked to nearby terraces and roads watched the demolition, after officials in helicopters conducted aerial surveys.

India has seen a construction boom in recent years but developers have often ridden roughshod over safety and other regulations, with the connivance of local officials.

The inhabitants of the apartment blocks in the well-off Maradu district of Kochi city had bought their 343 flats in good faith and now face a lengthy legal fight to recoup their money. Some had invested their life savings.

Sirens went off on Saturday warning people gathered for the demolition to remain at a safe distance while ambulances and fire engines stood on standby.

Ahead of the work, nearby residents told AFP they were worried about the impact of the demolition on their homes.

"When they were demolishing the swimming pool, some of the houses in our neighbourhood developed cracks, we are really worried," said Divya, who has moved into temporary accommodation.

Over 2,000 residents living in the neighbourhood were evacuated as a part of safety measures.
