WARWICK — The Silvas are to unwrap the bandages today and view the results of a week of construction surgery on their property on Yucatan Drive.

The family has spent a week at Disney World while scores of volunteers ripped down their old house, which was contaminated with lead paint, and erected a new domicile three times the size in a project sponsored by the ABC show Extreme Makeover: Home Edition.

The family returned from Florida yesterday, but were immediately cloistered in a motel room, according to Cathy Seibold of Oldport Homes of Portsmouth, which is overseeing the work. To make sure they don’t see the results until they arrive at 2 p.m., the Silvas were cut off from communication with the outside world, Seibold said.

“No access to TV, no news and no cell phones,” Seibold said.

But will the house be ready in time?

“Absolutely,” she said. “It will be ready ahead of time.”

Paul Fleming of Fleming & Co., a design company in Newport, said the show’s Web site segment on the rebuild project has been visited by one million Internet surfers.

The ABC show selects a needy family for each episode. The Silvas, who have two children of their own, plus three adopted children, all with disabilities, and two foster infants, were picked as the first Rhode Islanders to have their house demolished and replaced.

Extreme Makeover arranged for 200 companies to donate materials and services, and found 200 volunteers willing to do the work.

Yesterday, formerly quiet Yucatan Drive, off Warwick Avenue near T. F. Green Airport, resembled a, well, construction site. The rain and melting snow of recent days had turned the street into a sea of mud, spread for hundreds of feet by construction vehicles. Flocks of volunteers in blue T-shirts and white safety helmets swarmed around doing a bewildering variety of chores, while others put the finishing touches on the house. Neighbors’ lawns bore the deep imprint of construction vehicles.

Electrical wires snaked unnervingly across wet, muddy lawns where hundreds of spectators viewed the work from behind barriers. They whooped and hollered from time to time.

A miniature bulldozer helped workers lay rolls of turf in front of the new house. Stacks of bricks stood nearby for a purpose no one seemed familiar with. A heavy construction Dumpster rattled with debris tipped into it. Dump trucks rumbled.

Seibold, of Oldport Homes, said the plan is to bring the Silvas to the house in a limousine, but to shield the new creation from the family with a bus until camera crews are ready.

Then the spectators will yell, “Move that bus!’ she said.
