A home in a new Regina development was completely destroyed by a large fire Saturday morning. 

Emergency crews responded to Thauberger Road, in the northwest part of the city, at about 10:30 a.m. CST. 

Officials say the call came in from a neighbour across the street. 

"What we know at this time is premature as far as cause, origin and circumstance," says Randy Ryba, fire marshal for Regina Fire and Protective Services. 

Ryba says the home was still under construction and no one was living there. 

There was one man in the neighbouring home who managed to escape safely.

The inside of his house suffered extensive smoke damage though and there was some exterior damage as well, Ryba said. 

He also said it's very unlikely the man and his family would be able to return home before Sunday. 

"I'm assuming within a day or two for sure, " Ryba said. "There is no fire within their house but it is quite smoky in there so they're going to have to do some restoration." 

A fire investigator is on scene trying to figure out cause the blaze.
