Firefighters put out the fire in the double garage after being called to property in Narona Park on Casey Crescent at about 11pm.

There were no vehicles inside the garage but other contents were damaged.

The garage remains structurally sound, however the adjoining three-bedroom house sustained smoke and heat damage.

Intensive care paramedics took a 50-year-old man to the Canberra Hospital in a stable condition following smoke inhalation.

An electrical fault caused the fire.
