There was no report of any casualty, officials said.
Thick smoke was seen billowing out of the building engulfing the entire area.
The ceiling and wooden staircase of the building have collapsed. Fearing that the building may collapse, the police had evacuated the building, when the fire broke out at around 9.35 PM yesterday, and adjacent houses.
Traffic movement around Rabindra Sarani and nearby roads has been controlled as a precautionary measure.

"The fire is still not under control but we are fighting hard to douse it. As the building is located inside a narrow lane, it is difficult to reach there quickly," the officer said.
State Fire Minister and city Mayor Sovan Chatterjee was present at the scene for almost the entire night.
On the reason for the fire, the official said that it was yet to be ascertained but storage of inflammable materials quickened the spread of fire.
