When we wandered down to the build site of Extreme Makeover's project in Houston's Third Ward, we expected to see, well, a house. At least a frame. Maybe a foundation, at the very least?

But the Tuesday before the big reveal, which will happen Saturday, we saw a whole lot of mud, a whole lot of people, and as we got closer to the lot, a whole lotta nothin.' Volunteers are still waiting to assist as skilled workers race to put up the frame and whip the site into some semblance of a homestead. But no one seemed at all stressed.

They'd thrown up houses in breakneck speed all across the country, and even Extreme Makeover rookie, local builder HHN Homes partner Linda Stewart, seemed unfazed by the weather or the rush, calling the whole process "blessed" from inception — first phone call was mid-June — to fast-approaching finish.

However, organizers put out a call late Wednesday for additional skilled volunteers to get the house finished by the Saturday afternoon deadline. Torrential rains this week have put the team 15 hours behind schedule.

"We need framers. If anyone can help us frame we need to get them out here quickly because we still don't have a roof and the heavens are opening and it's raining down on us," carpenter/designer Paige Hemmis told Channel 13. "We need as much help as we can get."

The Houston episode is being touted as a "no tears show" for the irrepressibly upbeat family of seven (who had been living in a two bedroom, one bathroom house in serious disrepair) and comedic special guests. Even the door-knock took place at Houston's Improv Comedy Club.

Keep posted with CultureMap as the walls go up.

Channel 13, which broadcasts Extreme Makeover, has lots of photographs from the site, including Day 2 and Day 3 of the week-long construction.
