NEW YORK — The massive round metal mirror in the foyer was one of the first purchases Christian Siriano made after winning the fourth season of “Project Runway.”

The two small framed Victorian paintings in the living room were passed down from his mother.

And a turquoise-patterned pillow is Siriano’s own creation. He offers it at his newly opened namesake store, a 1,000-square-foot boutique where he sells his frocks, shoes and purses.

He seems to have a story about every one of the furnishings and accessories in his Manhattan apartment. They, in turn, tell a tale of a designer rising in his field yet finding refuge where he lives.

“Home is the escape from the formality of the world,” Siriano says on a visit during New York Fashion Week. “There are no boundaries. It’s all yours, and you can be creative with no outside limitations. It’s about comfort and love and living happily.”

That means, for instance, “I have about 50 pillows throughout my home,” he says. “I’m obsessed with chairs and pillows.”

Perhaps that seems excessive. But they help create the retreat Siriano seeks. After all, he admits that he spends much of his weekend lounging around his apartment, recuperating from his fast-paced weeks.

Brick walls and skylights

An in-demand designer and businessman, Siriano lives with his boyfriend of five years, Brad Walsh, and their two dogs, Bear and Topper. The 2,000-square-foot space is in Chelsea, in the heart of the bustling Fashion Avenue.

Blond wood floors and exposed brick walls set the stage. The one-bedroom apartment features two large skylights, while an oversized bedroom window casts bright cheer. The natural light also showcases the treasures the pair have amassed in four years of living together.

Each room, nook and wall tells a story.

For example, Siriano sees a large mirror with a gold frame and recalls the pain of moving.

“It was so stupid to get it here from our old Brooklyn brownstone,” he says, recalling the workers of his favorite moving company hauling that monster up five flights without an elevator to an apartment that was not yet fully furnished.

Still, “There were eight of them, and all they wanted was to break for lunch and eat chicken and broccoli. So there we all were, me and Brad, and the eight guys sitting on the floor eating chicken and broccoli. I was thinking to myself, ‘This is so nice.’ ”

Near the mirror is a large open space, where a tree typically stands at Christmastime. “During the holidays, there’s garland everywhere,” he says. “And it’s the best fake tree you’ve ever seen.”

Favorite funky antiques

A rustic-looking wooden tomato sign in the kitchen takes Siriano back to the time he and Walsh were antique shopping with actress Kristen Johnson of “3rd Rock From the Sun” fame.

“She came over to us and said, ‘Don’t you need this?’ ” Then she bought it for us.”

Most pieces in the apartment result from the couple’s favorite weekend activity: antiquing. They regularly hit up spots in New York and the surrounding area.

They’ve had plenty of success.

The kitchen contains several of the couple’s favorite pieces.

Walsh, a DJ, music producer and photographer, points out a red metal bread box, which they purchased online from an antique store. He saves his absolute favorite – a yellow 1970s Syndicate Manufacturing recipe box – for last.

“It’s from ‘Grey Gardens,’” Walsh says, revealing the couple’s love of the documentary about eccentric Jackie Kennedy relations on Long Island. “It’s the same one that Edie Beale gives her mother that contains the wedding jewels.”

“It’s really hard to find. But I found this on Etsy for $8.”
