Lyndsey Pearson, who lives near the scene, said people in the community had been left “devastated” by what had happened.
Ms Pearson said she was alerted to the blaze in the early hours of the morning by blue flashing lights, while her daughter had said she could smell smoke.
Speaking to the BBC, she said: “At first we thought it was a car on fire. We came out, but [the emergency services] wouldn’t let us past.
“They said it was a house fire and there were people inside. We could hear shouting.
“I just feel sick. It’s horrible. I just wanted to help, but what can you do? I’ve got grandchildren myself, so you think about them.”
