Firefighters worked throughout the night on Thursday (16) to put out a suspected arson attack on a thatched cottage in Shenley.
A fire broke out just before 6pm and six pumps, including two from St Albans, were sent to the property, in Silver Hill, Shenley.
The roof of the cottage has since collapsed, and a garage and two cars are heavily damaged.
Fire investigations are ongoing to establish what happened, as the cause of the fire is still unknown.
There were no people injured during the incident.
A spokesperson for St Albans Fire said that he believed the property was formerly owned by elderly man and has been vacant for six years.
Silver Hill Road, High Cannons Road, Well End Road, London Road, and Woodhall Lane were all closed until the Saturday afternoon.
If you have any information about what happened please contact Herts Police via the non-emergency number 101.
