"The fire is believed to have started in a property that was undergoing refurbishment work, at one end of a terrace of three properties in residential and office use. The upper storeys of the property collapsed during the fire. The neighbouring properties also suffered some fire and smoke damage.
"Firefighters will remain at the scene for some time yet and a fire investigation officer will begin looking into the cause of the fire later this morning."
