Even as this year’s Rockefeller Center Christmas tree twinkles away for millions of delighted visitors, last year’s tree is still bringing joy — as the beams and flooring for two Habitat for Humanity homes in upstate New York.

“Knowing that our walls contain the lumber from the Rockefeller tree will make the season even more special,” said Keith, a single father of three who will be moving into one of the homes in time to celebrate Christmas.

“For my family, celebrating Christmas in our new home for the first time is something that we are already looking foward too,” said Keith, who asked to be identified by only his first name.

Both of the homes are in Newburgh, and were gut-rehabbed by Habitat using wood from the 78-foot Norway spruce that graced Rockefeller Center last year.

In a way, it’s a homecoming for the stately tree.

The spruce had been cut from the front yard of Nancy Puchalski and Al Asendorf in upstate Gardiner just 16 miles away.

The tree was loved for four generations before its round trip to New York, said Puchalski, who grew up in Newburgh.

“Now it is going into homes for families that will hopefully have generations of love and family in their home, too,” she told Habitat for Humanity.

“It is beautiful to see it come full circle.”

It’s a nine-year tradition for the Rockefeller trees to be processed into lumber for Habitat for Humanity.

The current tree is a 94-foot Norway spruce that also hails from upstate, donated from the yard of a family in Oneonta.

It will sparkle until Jan. 7 — and then it, too, will be cut into transportable pieces right in the plaza.

The pieces will be trucked to a mill in New Jersey that does the initial rough sawing, according to the Rockefeller Center Web site.

From there, the lumber is dried in a kiln and then milled into finished beams.

The two newly rehabbed homes using 2015 Christmas tree lumber were dedicated at a celebration Saturday.

“We are grateful to be part of this tradition that takes this special tree from symbol, to lumber, to home,” said Cathy Collins, Habitat’s Newburgh executive.

The trees are donated to Habitat for Humanity by Tishman Speyer, the owner and manager of Rockefeller Center.

Volunteers from Tishman Speyer had joined Habitat in helping to frame the walls with the 2015 tree’s lumber.

To date, 97 low-income families have become Habitat homeowners in Newburgh after a lengthy process of sweat equity and homeownership classes.
