JUDY WOODRUFF: But first: Discussions about affordable housing often focus on big, expensive

cities, like San Francisco and New York.

But what about rural America, home to about one-fifth of the U.S. population?

John Yang reports on a program improving housing in a remote town in Alabama.

It's part of our ongoing series on poverty and opportunity, Chasing the Dream.

MARGARET "REE" ZINNERMAN, Rural Studio Client: Welcome to my house.

JOHN YANG: Ree Zinnerman was born in this tiny West Alabama town of Newbern, and, for

her, it will always be home.

MARGARET "REE" ZINNERMAN: It's a peaceful place, and I just like sitting here watching

it and listening to the quiet.

JOHN YANG: Soon, for the first time, she will move into a real house of her own.

For more than 40 years, she lived in a mobile home.

MARGARET "REE" ZINNERMAN: That's what I was living in.

JOHN YANG: Zinnerman's house comes courtesy of architecture students in Auburn University's

Rural Studio program.

MARGARET "REE" ZINNERMAN: Words can't describe it.

I couldn't believe it.

After all these years, something I have always wanted was a house.

And I was going to be blessed with the house of my own.

JOHN YANG: Since 1993, Rural Studio students and faculty have been working, studying and

living in Hale County, Alabama.

Some call it a lesson in social design, using architecture to serve the greater good.

Rural Studio's director is Andrew Freear.

ANDREW FREEAR, Director, Rural Studio: There's this sort of feeling that everybody deserves

good design, and whether they're rich, poor, black, white, pink, or green.

JOHN YANG: Zinnerman's house is part of the studio's 20K Project, launched in 2005, with

the goal of producing residences that would cost $20,000 to build, 20K.

More than two dozen different homes have been designed, constructed and given to residents.

Most are one-bedroom, about 500 square feet.

Each design is named for the recipient.

There's Johnnie Mae's House, Buster's house, and next to Ree's House, Geraldine's House.

That's Zinnerman's younger sister, Geraldine Braxton.

GERALDINE BRAXTON, Rural Studio Client: The day he gave me the keys to the door, I couldn't

even open the door, I was shaking so.

I was happy.

JOHN YANG: Braxton has lived here for two years.

The retired school cafeteria worker loves her kitchen

GERALDINE BRAXTON: I like everything about it, the way it's set up.

I like my island in the center of the kitchen.

JOHN YANG: Braxton's new energy-efficient house puts less strain on her wallet.

Her previous home was poorly insulated, it cost her hundreds of dollars a month to keep

cool in the summer and warm in the winter.

GERALDINE BRAXTON: I was spending like about $350 on gas in the winter every month.

JOHN YANG: Three hundred fifty dollars a month?

GERALDINE BRAXTON: Every month for gas.

JOHN YANG: While Rural Studios is helping improve the lives of local residents, the

main focus is on training a new generation of architects whose social consciences are

as strong as their aesthetics.

ANDREW FREEAR: What we're trying to do is design a home that is easily built, and, again,

easily maintained.

You know, our goal is to offer it up at some scale down the road, but we're determined

to do it quietly and slowly and carefully.

JOHN YANG: The idea is to give students a hands-on experience working with an underserved

community in the heart of the South's Black Belt.

Hale County is one of the poorest in the state - - 24 percent of all residents live below

the poverty line, compared with about 13 percent nationwide.

For African-Americans in the county, the rate is even higher, more than 35 percent.

And in an area short on jobs, the population is dwindling, dropping 6 percent from 2010

to 2017.

Since the students live full-time in Newbern, some 140 miles from Auburn's main campus,

they're seen not as outsiders.

They're seen as neighbors.

MARGARET "REE" ZINNERMAN: I think it makes a difference by them being part of the community,

because they have really improved it.

JOHN YANG: And they ask their neighbors to suggest who could use a new house.

GWEN MELTON, Mail Carrier: And it was just sad for anybody to be living in those conditions

in these days and times.

JOHN YANG: Who better to ask than Gwen Melton, who delivers mail to 483 homes in the Newbern

area every day?

For 10 years, she's quietly suggested potential clients to Rural Studio.

And how does it make you feel when you go deliver the mail to that new house, knowing

what they had lived before?

GWEN MELTON: Makes me feel great.

JOHN YANG: The 20K Project began with lofty goals.

Rural Studio associate director Rusty Smith oversees the project.

RUSTY SMITH, Rural Studio: We thought we were going to work for a year or two or maybe three,

and it would solve all the problems of housing affordability in the United States.

JOHN YANG: It didn't take them long to realize the hurdles to doing it on a bigger scale.

RUSTY SMITH: We're in charge of the financing, and we're in this place where we live, and

we have got student labor to do it and the faculty oversight.

The challenges to scale, to kind of do this outside of our kind of operational footprint,

are many.

JOHN YANG: Still, they want the project to focus attention on the issues facing rural

areas, not just in America, but around the world.

ANDREW FREEAR: It's absolutely a Trojan horse for a whole bunch of issues about rural living

that we're very interested in challenging and being a voice for.

JOHN YANG: For instance, cell service in Newbern area is spotty.

The town's new library, designed by the Rural Studio, is the only place high-speed Internet

is available to the public.

BARBARA WILLIAMS, Librarian: It makes you feel real good to be able to say that we have

a library.

JOHN YANG: Librarian Barbara Williams says that when the nearby high school closed five

years ago, the town lost a community hub.

BARBARA WILLIAMS: What the library is trying to do is to try to meet some of the needs

of the community that are being left, I guess left unmet with the closing of the high school.

JOHN YANG: Across the street is Newbern's fire station.

Built by the Rural Studio in 2004, it was the first new public building in the town

in a century.

Pat Braxton lost his job in 2013 when the factory where he worked the next town over

went out of business.

Now he's a volunteer firefighter and Newbern's handyman.

Before, the nearest fire station was 15 minutes away.

PATRICK BRAXTON, Handyman: By having this truck right here in Newbern, we saved a lot

of houses.

We saved a lot of people's lives.

JOHN YANG: And saved Newbern homeowners a lot of money, reducing insurance premiums.

Like all of Rural Studio's projects, style also has function: There are no fire hydrants

in Newbern, so the fire trucks carry their own water, and have to be kept from freezing

in the winter.

ANDREW FREEAR: It's not just it looks funky and it look cool.

It's very much about making sure that those fire trucks don't freeze and that that space

is temperate throughout the year.

JOHN YANG: Ree Zinnerman gave students free rein to design her house, except for one detail.

MARGARET "REE" ZINNERMAN: A red door.

And my momma always loved red.

JOHN YANG: For Zinnerman, the greatest relief is simply having a well-designed, well-built

house to live in.

For Rural Studio, it's about more than just solving a housing problem.

RUSTY SMITH: Solving problems sort of imagines the future as broken and it needs to be fixed.

I don't think there's anything broken here.

But there's some really significant purposes that need to be served.

JOHN YANG: A lesson for students in helping an underserved community and helping the community

learn how to better serve itself.
