Two nontraditional retailers, QVC and HSN’s Cornerstone division, along with Target, are scouring the West 34th Street area for new spaces to ply their wares, sources say. And Amazon wants something right on West 34th Street, sources add.

Both multichannel home-shopping retailers have independently decided the teeming shopping area is ripe for a brick-and-mortar store to complement their TV shows and online retail.

The shopping networks already have scattered outlets but none in New York City.

QVC has outlets at its studio in West Chester, along with Frazer and Lancaster, all in Pennsylvania, and at the Tanger Outlets in Myrtle Beach, SC, and perhaps others.

HSN’s only outlets are in Florida — in Brandon, Largo, New Port Richey, Sarasota and Tampa. HSN’s Cornerstone division operates 14 outlets for its Frontgate, Ballard Designs, Garnet Hill, Grandin Road and Improvements catalogs.

Target, which has just opened its 45,000-square-foot Financial District store at 255 Greenwich St., is now focusing on a 5,000- to 10,000-square-foot space along West 34th Street.

It is also trying to capitalize on the Nordstrom effect and looking for storefronts in the Billionaires’ Row area.

That online all-category killer is spreading out from its offices at 7 W. 34th St. but is also seeking a retail location on the infamous shopping strips found around West 34th Street and Fifth Avenue.

“Everyone wants to touch the customer,” said Faith Hope Consolo, chairman of Douglas Elliman Retail, who has high hopes one of the lookers will cut a deal for her 22,000 square feet at 345 Fifth Ave. across from the Empire State Building. With two floors and a lower-level frontage area — amassed from a former McDonald’s and two tourist stores — the ground asking rent is $400 per square foot, lower than others in the area.

Representatives from the retailers did not immediately respond to requests for comment.

As The Post reported last week, the world’s No. 1 investment sales broker, Douglas Harmon, has just joined Cushman & Wakefield and brought along former Eastdil Secured colleagues Adam Spies and Kevin Donner , who became chairman and executive managing director, respectively.

In his first interview, Harmon, who completed $50 billion in sales in just the last two years, told us he can now provide clients the full global reach and transaction depth afforded by Cushman & Wakefield.

“At Cushman & Wakefield, we uniquely combine capital market and global and local real estate, along with leasing expertise that will provide clients with outstanding execution and advice in almost all markets, property types, transaction shapes and sizes,” Harmon says.

Bungalow 5 is relocating its to-the-trade interiors showroom to 5,000 square feet on the entire second floor of 45 E. 20th St.

Elie Reiss of Skylight Leasing represented the tenant in the expansion and relocation from the Garment Center at 251 W. 30th St. The new building not only sits between Union Square and Flatiron but also has oversized windows for natural light.

John D. Goodkind of Koeppel Rosen represented this Rosen family building, which has an asking rent of $62 per square foot.
