Staff at the Original Factory Shop in Fakenham have been praised for leaving the building so quickly once the fire alarm sounded.
Marketing Director Colin Leggatt said workers got shoppers out and left immediately without going back for their possessions. Phones, car keys and bags were all burned.
Mr Leggatt said the company was trying to find work for the 12 employees at its other branches in Dereham and Snettisham while it looks for other premises in Fakenham. It'll hold a staff meeting tomorrow.
Staff are also being offered counselling to help them come to terms with Sunday's blaze. The company says work to find out what started the fire may take some days.
A store destroyed in a blaze over the weekend continued to smoulder today as fire fighters said the building was unlikely to be saved.
Firefighters who spent all weekend tackling a blaze in Fakenham town centre have released photographs showing what they had to deal with.
