Ty and the "Extreme Makeover: Home Edition" designers will be visiting both St. Louis and Ballwin, Missouri to give Dawn Martirez a safer home for her special-needs children, and to remodel Sam Malek's coffee shop that employs disabled individuals and donates a portion of its earnings to charity.

"Extreme Makeover: Home Edition" will be traveling to Holt, Michigan, to help the Nickless family rebuild their lives after the tragic loss of their husband, Tim Nickless, which left Arlene and her three sons to fend for themselves in an 1860s dilapidated home.
