BETHLEHEM, Pa. -

Tucked into Historic Bethlehem, on an East Church Street plot once owned by the family of William Penn, sits a Federal-style mansion, the Society of the Arts 2014 Show House.

"Designers come in and do their work, make the magic happen," Mary Douglass of the Society for the Arts said.

Over the next month, 22 designers will transform the home.

The goal is to make the past come alive by incorporating the already extensive antique collection.

"Largest fund raiser we do on behalf of the art museum," Douglass went on to say.

Over the past 50 years, SOTA volunteers have raised over $1.1 million for the Allentown Art Museum.

Museum head David Mickenberg says the bi-annual show house event is a key fund raiser.

"It pays for educational programs in the museum that allows us to outreach in the community, partner with K-12 with the Allentown School District," Mickenberg said.

It's not only the art museum that gets a boost.

This is also a big opportunity for local designers working both outside and inside the home.

Macungie designer Jess Edgar figures she'll spend 25 to 30 hours transforming this guest bedroom.

It's all done for free, but Edgar says the exposure can lead to big business.

"A lot of people come to this. Even though they have to pay it's a good thing because they're serious about what's here," she said.
