New details have revealed the huge scale of Norfolk's first Costco store. 

The American discount retailer unveiled plans for a new warehouse at Broadland Business Park earlier this month.

While Costco is yet to submit a formal application to Broadland Council, it has shared initial designs for the site, which spans more than 13 acres and includes 625 car parking spaces.

The 13,342 sqm warehouse will stock bulk goods aimed at business owners in Norwich and operate on a membership-only basis.

The proposed development at Broadland Business Park, also home to a Premier Inn, Costa Coffee and the Broadland and South Norfolk Council offices, will include a petrol filling station and electric charging points, and is expected to create 250 new jobs. 

While locals have raised concerns about overdevelopment of the site and increased traffic in the area, Costco bosses say the morning rush hour would not be impacted by customers as the store does not open until 10am on weekdays.

"The employment opportunities associated with Costco will bring benefits to Norwich and will provide a broad range of quality jobs that reflect the unique nature of our operations."

Costco is carrying out a public consultation on the plans until 5pm on September 27 after which it will submit a formal planning application to Broadland District Council. 

Members of the public will have another chance to comment on the designs as part of the council's usual planning process.
