The “House of Tomorrow” opened to curious members of the public Saturday and transported them back to a not-so-distant and very retro past.

The Harold Hess Lustron House – a prefabricated 1,000-square-foot house made of maize yellow enamel steel – was opened to the public just four years after it was saved from the wrecking ball.

The Friends of the Lustron House and the Closter Historical Society showed off the two-bedroom, one-story house to a steady stream of visitors from the neighborhood and beyond.

The visitors were greeted by volunteers in period costume suitable to 1950, which is when the house was constructed after it arrived on a specially-designed truck.

The women wore pearls, white gloves and pill box hats. The men wore suits and Runyonesque fedoras.

They served up punch from a cut glass bowl in rooms stocked with vintage furniture, toys and magazines that looked like props from a 1950s sit-com.

“It’s like re-enactors,” said Jennifer Rothschild, chairwoman of the Friends of the Hess Lustron House. “Only we’re mid-century re-enactors re-enacting a punch bowl party.”

Neighbors like Ed and Rita Walsh, who had been curious about the house as they passed by, were impressed by what they saw inside.

“This is amazing,” Ed Walsh said. “I wouldn’t expect something like this to stand up as long as it has. It’s in amazing shape.”

His wife Rita added: “It’s so unique. How many people have this in their neighborhood?”

Very few as it turns out. There are only two Lustron houses remaining in Bergen County with the other in Alpine. There are nine left in New Jersey and about 1,500 nationwide, Rothschild said.

The name Lustron was derived from the term “luster on steel.” The homes were built from surplus steel and marketed specifically to returning World War II veterans looking for a simple and affordable house.

One of those veterans was Harold Hess, who saw a sample Lustron home on display at Palisades Amusement Park. He ordered a Westchester Deluxe model with a breezeway and an attached garage.

Hess originally wanted to build it in Fort Lee. But when he could not get a permit for the pre-fab house, he located instead in Closter.

The house has some interesting quirks. All the decorations are hung on magnets. Cleaning the steel panels involved polishing it with the same kind of wax used to polish cars.

Yet for all its mid-century design, the simple interior has a curiously modern feel.

“It was considered the house of tomorrow,” said Irene Stella, the president of the Closter Historical Society.

Hess purchased one of the last of the 2,498 homes manufactured by the Lustron Corporation before the company went out of business in 1950.

Hess died in 2004. A developer who later bought the house agreed to donate it to the borough as part of a deal that allowed him to purchase a neighboring property.

Sophie Heymann, who was Closter mayor during those negotiations, said she felt “a sense of pride and accomplishment” seeing people come through the house Saturday. Heymann said she also was grateful for the borough’s support of the project.

“It’s great to see people coming in and enjoying it,” she said.

Mike Pisano, the volunteer caretaker of the house, said the house is a special place.

“Sometimes I come here to do a little bit of work on the house and it just calms me down and brings me back to a much simpler time in life, which is very rewarding,” he said.

Volunteers hope to continue with public tours and other events. For more information, email them at LustronFriends@gmail.com or visit their Facebook page at “Friends of the Hess Lustron House.”
