The shopping center itself opened in 2008 on site of the former Home Depot. The former 128,000 sq.ft. store was demolished and replaced by a 111,800 sf. plaza with a smaller parking lot. 

Christmas Tree Shops and Bed, Bath & Beyond opened in the new plaza. A third retailer could have joined the two stores later but the remaining lot stayed vacant. This site is located alongside the Spaulding Turnpike, at the end of Durgin Lane after passing by the Durgin Square and PepBoys. It is connected to Gosling Avenue via a small private roadway leading to a Motel 6.

In April 2023, Bed Bath & Beyond filed for bankruptcy and confirmed it would close all remaining stores, so the Portsmouth location likely closed in 2023. As of 2025, the property is vacant.  Early in 2026, the former Christmas Tree Shops plaza was razed. A residential project called The Residences at Durgin Lane will be built on the property.

Back to Costco, there were some rumors that it could make a comeback to the NH Seacoast. A warehouse club was proposed for the former Fox Run Mall in 2025 and was confirmed in 2026.
