Nobody was in the property on Bank Edge Road, Ovenden, when the blaze broke out at around 1am on Wedenesday morning.
However, a neighbour, his wife and eight-month-old daughter were grateful for their smoke detectors which woke them after their house became smoke logged.
He said: “I had just put our eight-month-old to bed when I heard a bang but I thought it was just the wife getting out of bed.
“I went outside for a smoke and there was nothing I could see so I went to bed. Next thing I know I was being woken up by smoke alarms.
“The house was full of smoke - I was panicking but trying to stay calm for my wife and daughter.
“At first I thought it was our house on fire and I saw a lot of smoke passing the front door like a big cloud.
“I didn’t want to open the front room door in case the fire was in there but then I saw it was next door and we just rushed to get outside.
“It was only a few minutes but it felt like a lifetime.”
The family waited on the other side of the road as they watched the house next to theirs engulfed by flames.
“It was like an inferno,” he said. “I was worried about our house but just so focussed on making sure my family were alright.”
Firefighters from Illingworth and Halifax attended at the scene and found the house engulfed in flames.
It took them 20 minutes to bring the blaze under control but they were at the scene for three hours in total.
Craig Horsfall, 26, who lives nearby, said: “I was just eating a takeaway when I heard something going on outside.
“The fire was going all through the house. It started downstairs and you could see it moving round.
“There were flames coming out of the back window and the front window had just melted.
“The next door neighbours have a nine-month-old baby which they had to take over to the other side of the road.
“It was so hot - I’ve never felt anything like it.”
The house was empty but was just being refurbished for new tenants to move in.
The cause of the fire is still being investigated.
