Fire services have reassured residents there is no danger.
The dream is over for X Factor finalist Jake Sims from Warmley in South Gloucestershire.
His boy band Stereo Kicks were voted off the ITV competition in the quarter finals, leaving only four acts remaining.
They fell foul of the public vote after the judges were split between the eight-strong band and 17-year-old Lauren Platt.
Simon Cowell had the critical vote to either save the group or force a deadlock and defer to the public vote.
He said: "The act that sang the best on the sing off was Lauren," voting to keep her in the competition.
Cheryl Fernandez-Versini stood by her act, Lauren Platt but told the boy band they had talent and could still grow.
Louis Walsh also stood by his act, Stereo Kicks.
Mel B voted in favour of the boys too, apologising to Fernandez-Versini before she said she had to vote for Lauren Platt to leave.
Some members of the boy band wept as their X Factor stint came to an end but said they were thankful to have been on the show.
Speaking on the Xtra Factor afterwards, Simon Cowell told Louis Walsh his poor song choice was to blame. But Walsh insisted: "I did 100% the best I could and they know that. They'll tell you that later."
But Jake Sims will still have a shot of the limelight - Stereo Kicks will be taking part in the X Factor Live Tour in 2015.
Jake Sims from Warmley in South Gloucestershire is in the final five of the X Factor. His band, the eight-strong Stereo Kicks, were voted through without a hitch this weekend after performing Sir Elton John's "Don't Let The Sun Go Down On Me".

The eight-piece boy band was in the bottom two last weekend, staying only when Chloe-Jasmine Whichello lost the sing-off.
But the boys turned it around on Saturday’s show, performing a medley of The Beatles classics “Let It Be” and “Hey Jude”, which was enough to see them, straight through to next week.
Their success comes after rumours that at least one of the boys would be made to leave the competition after their mentor Louis Walsh admitted that he never wanted the group to have eight members.
But as he introduced them last night he said “Eight boys, and I did say eight – the ultimate octoband.”
Their performance impressed Simon Cowell, who praised the boys for sticking together and added "Any time you want to leave Louis, and come and join me, I'll mentor you."
It was the battle of the boy bands on this weekend's X Factor. Both bands had members from Bristol.
But it was the end of the road for 19-year-old Ollie Garland from Warmley and his band Overload Generation. Their X Factor journey came to an end on Sunday night when they were voted off the show.
Judges Simon Cowell and Cheryl Fernandez-Versini described their performance in a sing-off with Stephanie Nala as "shockingly bad".
Meanwhile Bristol teenager Jake Sims's band Stereo Kicks is through to the next round of the show.
Both bands, mentored by Louis Walsh, sang hits by Katy Perry. Judge Simon Cowell said they blew Overload Generation off the stage with the performance.
Former Wells Cathedral School pupil Chloe-Jasmine Whichello is also through to the next round after she pulled off a fantastic jazz rendition of Britney Spears’ hit ‘Toxic’.
