A neighbour, Maxine Lattimer, told him the blaze looked like a very large bonfire, then she saw a tree set alight. "Our whole back garden is covered in ash," she said, "It burnt a hole on our trampoline.
"[The flames] went right up through the tree."

Firefighters struggled to contain a ‘well developed and rapidly moving fire’ in Maidenhead last night.
At approximately 9pm, fire crews in Maidenhead received a call about a small shed fire at a property in Belmont Crescent.
However on their arrival it was apparent that was not the case and that two other sheds were involved as well.
Watch manager Steve Hogg said: “At that moment in time we were dealing with a well developed and rapidly moving fire which we struggled to contain as it was quite a big fire.
“Other residents were concerned about the fire spreading to their home so we had to protect them and prevent further damage.”
Four fire engines were used to tackle to blaze; two from Maidenhead, one from Slough and one from Windsor.
They used four jets, two hose reels and two sets of breathing apparatus.
The fire crews left the scene at 1.30am.
At present it is not know how the fire started but an investigation is underway.
Sinead Kiddle, who lives in Belmont Crescent, said: "It was really scary.
"I have got a canister of petol in my shed and I was thinking 'Oh my God that's going to go up'.
"Thankfully nobody was hurt and what an amazing job the firefighters did."
