Teams saved several people trapped in the level as the fire ripped on Sunday evening.
The blaze broke out and then locals said they heard an explosion also it rapidly spread to the flats upstairs as well as adjoining stores.
Countless people shed on to the road below as fires ripped through heavy, black smoke billowed to the sky and the old building.
Families, some with little kids as well as in tears, given blankets by ambulance teams and were evacuated from their houses.
An administrator whose level is across the road, Sarah Pheby, 28, said in the time: ‘The fire seems apocalyptic.
She said fire fighters in cherry pickers were sent as much as individuals trapped in the flats above.
Approximately 15 fire engines and tons of crew ran to town centre to attack the blaze, that they fought for hours.
There are not any reports of harm that is serious.
