NEW YORK — J.C. Penney is honing in on its home department as part of a bigger plan to turn its stores into mini-malls, of sorts.

The struggling department-store chain is unveiling revamped home areas within its stores that feature 20 boutiques and 50 new brands. The areas will include an eclectic mix of items, from $60 Michael Graves’ stainless steel tea kettles to $1,850 Jonathan Adler “Happy Chic” sofas.

The home areas, which Penney will begin to roll out Friday at 500 of its 1,100 stores, will test CEO Ron Johnson’s plan to open separate shops-within-stores for popular designers. The format, which gives department stores more of a mini-mall feel, have been popular at higher-end rivals such as Macy’s and Bloomingdale’s for years.

Penney, which already has rolled out mini shops-within-stores for popular clothing designers like Joe Fresh, hopes the new home areas will help it woo back shoppers. The chain is struggling to rebound its business after losing a quarter of its revenue and amassing nearly $1 billion in losses in the past year since it began tweaking everything from its pricing to its stores. The revamp of the home areas presents a big opportunity for the retailer to regain its footing.

While home sections typically are among the least profitable of a department store, they help to drive customers into the store. And demand for home furnishings is rebounding along with the U.S. housing market: Sales of furniture and home decor reached $92.9 billion last year, up 7.8 percent from the low of $86.2 billion in 2009 during the recession, according to spending tracker MasterCard Advisors’ SpendingPulse.

“It’s going to be a struggle, but the home area could generate some momentum,” said Walter Loeb, a New York-based independent retail consultant.

But Penney, based in Plano, Texas, has its work cut out for it. Penney was planning to anchor its home areas with the Martha Stewart lifestyle brand. But the company is fighting in court with Macy’s over whether Macy’s has exclusive rights to sell certain Martha Stewart products such as bedding, cookware and bath items.

Adding to that, Penney’s home business has lost considerable cache from its heyday. The business once accounted for nearly 20 percent of Penney’s total store sales, but that number has dropped to 12 percent as the assortments have failed to attract the younger customers who update their homes more often than their older counterparts. In fact, Penney said that its home department, which had attracted an average age of 45, has the oldest shopper compared with rivals like Target Corp. and Macy’s.

Penney executives say the new sections will appeal to a broader group of customers. About 70 percent of the merchandise in the new home area will be new or retooled brands. To make room for the new labels, Penney got rid of long-standing names, including traditional home furnishing brand Chris Madden.

Each shop-within-a-store will have its own distinct look and will range in size from 300 to about 800 square feet. Among the new shops within the stores will be Bodum, a Denmark-based kitchenware company. Jonathan Adler, known for his whimsical designs in home decor, also will have a shop. And Michael Graves, the architect-turned-home designer, will showcase his minimalist style in kitchen and home accessories in mini boutiques.

“There’s something for everyone at any stage of their lives,” said Paul Rutenis, senior vice president and general merchandise manager for Penney’s home business.

The Graves shops for Penney will have about 150 items, ranging from $8 wooden spatulas to $190 standing lamps.

Graves said the quality of his items in Penney’s stores is higher than the items he once sold at Target: A teakettle at Target, for instance, sold for $39 and was plastic, but Graves said the $60 Penney version is stainless steel.

As for Penney’s future, Graves said he’s focusing on what Penney will become.

“I’m not at all worried,” he said. “The change is going on. People will have to be patient.”
