LONG BEACH - A Long Beach family who lost their home to Superstorm Sandy got the surprise of a lifetime today.

The crew from HGTV's "Spontaneous Construction" and dozens of friends and neighbors surprised the Enright family with a flash mob outside their Long Beach home. Show executives say they plan to completely renovate the house, which was destroyed when Sandy hit in October.

The family of eight has been living on the second floor of their home since Sandy flooded the first floor with 6 feet of water. They have been sharing three bedrooms, and their bathroom has been doubling as a kitchen.

The Enrights were overwhelmed and thrilled by the news.

"It's unbelievable," John Enright said. "I'm speechless right now. I just can't believe what everyone is doing for us."

The new home will be revealed to them next Saturday.
