KIRKLAND, Wash. -- After a week and one day of working under extreme conditions, the crew "Extreme Makeover: Home Edition" has finally finished work on the Chapin family's new home.

The Chapins will get their first look inside their new home on Thursday morning, but dozens of anxious onlookers began filling the street outside the house on Wednesday evening.

The house was supposed to be revealed on Wednesday, but problems and wet weather at the site forced the show's producers to delay the family's return.

The popular show in which a new house is built in just a week has to scramble with every project, but this is only the third time in the show's history that they've needed extra time.

The project to build a home for the Chapin family began last Wednesday when the show's bus rolled up to the front door and host Ty Pennington informed the Chapins that they'd be getting a new house.

The home was made with toxic paint and insulation, which prevented the construction crew from just knocking it down like they usually do. The house had to be taken apart piece by piece.

Then, several days of wet weather put the construction effort way behind schedule. And on Monday, a fire at a nearby hotel left the show's landscapers being treated for smoke inhalation.

So, the call went out for help online, on TV and on the radio, and hundreds of extra volunteers showed up to work on the home.

But even with the extra workers, construction crews weren't able to finish in time for the family's scheduled return Wednesday evening.

The show's producers now plan to unveil the home on Thursday.

"Well, you know, we pull off miracles every week. We build a house in a week, every week. But uh..." said Johnny Littlefield, a member of the show's design team, of the setback.

After fighting wet and muddy conditions all weekend, one of the show's designers told KOMO 4 News the next time the show visits a home in Western Washington, it will be in July, not October.

Volunteers from around the state are working to help finish the home for Connie Chapin, who supported her four children after her divorce by teaching kids to swim in her old backyard pool.

"They'll be very happy with what they see," said Nancy Allen, a volunteer.

Those who want to attend the unveiling should head to Totem Lake Mall and catch a shuttle to the Chapins' home. That shuttle is scheduled to leave no later than 7 a.m.

Others who want to see the Chapins' new home on their own can find the home at 10203 116th Street in Kirkland.

The show's crew is also sending out a call for volunteers to work on Thursday and Friday to help clean up the neighbors' yards.
