The damage to one of Windsor's Victorian-era is severe after a fire early Monday morning on Victoria Avenue.
Firefighters were called to the home near Elliott Street West around 2 a.m.
No one was hurt, but the home's roof collapsed.
Damage is estimated at $700,000.
Investigators listed the cause of the fire as undetermined.
Meanwhile, crews have begun demolishing a home that went up in flames last week on Ouellette Avenue.
The so-called "Rainbow House" was destroyed in the fire on May 2.
The Windsor Police Service Arson Unit is investigating that fire.
