One family are grateful to be alive after a massive sinkhole opened up in their back garden stopping just three feet from their home.

Lou and Denise Lambros and their four children were immediately evacuated from their Florida home after the huge hole, that measures 100 feet across and nearly 50 feet deep, suddenly appeared overnight.

A few days after the 'unreal' incident, Lou Lambros says it has sunk in that his family narrowly escaped potential tragedy and spoke of his relief that none of the neighbourhood children, who often came to play in the garden, were hurt.

Unbelievable: It took Denise Lambros a few moments to comprehend what she was witnessing when she first saw the sinkhole.
'It is almost frightening for me. I know that my kids played back there...neighborhood children used to come over to play,' he told MSNBC Today.

The cause of the sinkhole is unknown, but officials believe the dry weather conditions experienced in parts of the south could have contributed to the hole.

Lambros admitted that it finds it hard to look at the hole, which is getting bigger, adding, 'We feel that God saved us from a tragedy.'

Close call: Although they are temporarily homeless the Lambros family spoke of their relief that no one was hurt in the freak accident.
The hole ends a mere three feet from the family's two-storey house, which they had only moved into two months earlier.

Denise Lambros discovered the pit in their backyard around 7am on Saturday morning when she let the dog out.

'The earth open huge and huge chunks of dirt fall in. I witnessed a tree slide down into it,' she told Msnbc.

Deep and wide: The hole measures around 50-ft deep.
She admits that it took her a few moments for what was happening to sink in then rushed back indoors to wake up her husband.

When the Orange County Fire Department arrived, they told the young family to gather as many personal belongings as they could and evacuate, along with their pet cat and dog.

The house was deemed unsafe to live in.

According to clickorlando.com, the family is relying on help from friends and relatives and are living in temporary housing.

They are moving all their possessions out of their home into the garage, which is further from the hole.

'The ground was just falling into the hole, and the trees were gone,' Lou said on Saturday. 'It was happening very rapidly, too.'

According to WESH, geological experts are currently evaluating the hole.
