Houston, Texas (CNN) -- Alexander Reyes' boyhood dream of a military career ended when he was hit by an improvised explosive device during a patrol two years ago in Baghdad. 

"Laying in that hospital bed ... sometimes I felt I'd rather [have] died," Reyes said. "My life came to a complete halt." 

Reyes sustained severe blast injuries that led to his medical discharge; he's on 100 percent medical disability. Like many soldiers wounded in Iraq and Afghanistan, Reyes, now 24, found the transition to civilian life difficult. 

But he and a handful of other injured veterans are getting help from what may seem an unlikely source: a custom home builder in Houston, Texas. 

Dan Wallrath recently presented Reyes and his wife with an unexpected gift: a home built especially for them, mortgage-free. 

"Thank you. That's all I can say," Elizabeth Reyes said, sobbing and clutching her stunned husband's arm as Wallrath surprised them with the house. 

For Wallrath, giving wounded veterans a place to call home is his way of saying thanks. Since 2005, his organization has built four houses. Five more are under construction, and he's expanding his idea into a national campaign called Operation Finally Home.

Wallrath spent 30 years making upscale clients' dream houses a reality. But he found a new mission in 2005 when he met with Steve Schulz about a very different type of project. 

Schulz's 20-year old son, a U.S. Marine, had been gravely injured in Iraq. Schulz desperately needed to remodel his house to accommodate his son's wheelchair.
