Stunned neighbours watched in horror as new build properties went up in smoke on a new housing estate.
The blaze was caught on video as it ripped through the partially constructed homes, causing £500,000 worth of damage.
The footage was shot on Friday night as fire crews were called to the scene, Renfrewshire Live reports.
Residents say the smoke could be seen for miles as the flames engulfed the houses.
Others feared flames could spread to the homes, and praised the firefighters for their swift response.
The drama unfolded at Merchiston Oval in Brookfield village, near Johnstone shortly after 7pm.
One neighbour told Renfrewshire Live: "It was pretty scary. You could see the fire ripping through they houses with more and more flames appearing through the scaffolding.
"You could probably see the smoke for miles as it just seemed to be getting bigger and bigger at first.
"It's just a good thing nobody was hurt and they new builds aren't occupied yet, but it was still a terrible thing to see."
Another explained how neighbours rushed out their homes to see what had happened. She added: "I had just walked into the living room and fire engines began speeding past the window with their sirens.
"I looked out and could see the smoke and went out after. Everybody looked pretty shocked. I think we were all just worrying who was living nearby.
"Within about an hour it was just some smoke and a few fire trucks parked on the street. You could see them hosing what was left from the fire from the roof. They must've been very prompt at dealing with it all."
Some neighbours could see the inferno from their gardens and driveways as they feared it spreading to other properties and surrounding fences.
Fire crews were seen dealing with the incident at the construction site - where scaffolding remains in place for the homes still being built.
They also taped off nearby Barrochan Lane with water pipes spotted trailing up the street to where the incident took place.
Other nearby residents took to social media to comment on what happened.
One local said: "Definitely a godsend that no-one was hurt", while another agreed, saying: "Thank goodness it was one of the houses that aren't inhabited yet."
A third resident stated: "The fire brigade also need our thanks for tackling the fire and it makes us appreciate the amazing job they do.
"We are upset for the people who are due to move into the houses but thankful that no-one was hurt."
Police launched an investigation on Friday evening over an alleged deliberate fire.
They have since confirmed two youths have been charged in connection.
A Police Scotland spokesperson said: "Two boys, aged 13 and 14, have been charged in connection with wilful fire raising at two properties in Brookfield, Johnstone.
"They will be reported to the Children's Reporter."
