Firefighters arrived to find the home engulfed in flames with heavy smoke conditions.

It took crews several hours to knock down the blaze at the two-storey home.

Large plumes of smoke could be seen from parts of the lower city.

Four adults and three children managed to get out unharmed. Police say they have found alternate accommodations with family.

Damage is estimated at $1.2 million.

The house had been undergoing extensive renovations since last spring.

The Office of the Fire Marshal was on scene but the cause is still undetermined.
