Keene Planning Board members, from left, Gary Spykman, Douglas Barrett and Nathaniel Stout listen Tuesday to Jeffrey Taylor of Taylor Associates Architects explain plans to convert a vacant retail space in the Riverside Plaza into three storefronts.

A large and vacant retail space in Keene will be split into three units, according to representatives from the company that owns it. They also say tenants have committed to two of the three spaces.

HomeGoods and Harbor Freight stores are expected to open next year in the former Shaw’s space next to the Walmart in the Riverside Plaza on Winchester Street, DLC Management Corp. personnel said Tuesday at a Keene Planning Board meeting.

DLC, an Elmsford, N.Y., company that owns and operates shopping centers, is also close to leasing the third space to “another national tenant,” according to Glenn Wilson, its director of construction.

The planning board approved the project Tuesday night, conditional on adding a bike rack to the plans and completing a few other administrative steps.

The proposed work involves renovating the space’s interior, building three distinct entrances and facades for the new units and adding three new loading docks and a receiving ramp behind the building, according to application materials.

“It’ll tie in with the existing shopping center, and it’ll look like a new facility,” Jeffrey Taylor of Taylor Associates Architects in White Plains, N.Y., said Tuesday while presenting the renovation plans. Noting the extended vacancy in the building, he added, “I think it’s a welcome improvement.”

Shaw’s supermarket, which previously filled the space, left in 2013, citing a lack of profitability. The 66,000-square-foot space has sat vacant since, except for brief periods of occupancy by a pop-up Halloween store.

With the board’s approval, DLC can now apply for the administrative permits it needs to begin construction.

After the meeting, Wilson said he expects construction to take six months. The stores could open in fall 2019, he said.

HomeGoods operates more than 500 stores around the country, according to its website. The chain — owned by the same parent company as T.J. Maxx and Marshalls — sells home decor, kitchenware, bedding, bathroom accessories, outdoor furnishings and other home products.

Its New Hampshire locations include Bedford, Nashua and Lebanon.

A spokeswoman for the retailer declined to comment, writing in an email that “HomeGoods has not announced a new store for Keene.”

Harbor Freight, a retailer advertising “quality tools at ridiculously low prices,” has more than 1,000 locations nationwide, according to its website. The company did not immediately respond to a media inquiry sent after business hours Tuesday.
