The first stall has opened inside Great Yarmouth's new £4.7m market space.
Since the beginning of last April, the town centre has been dominated by the sight of the ongoing marketplace development.
On Tuesday, Sal and Sandra Nowman's business - Extra Essentials - was the first of the stalls to open inside the new build.
Among other things, Mr and Mrs Nowman sell watches, straps and batteries.
Mr Nowman, 59, said it was nice to be the first business inside the new market, but added: "it will be even nicer when the other traders are in and the market is fully operational".
Essential Extras had previously been on the old market site for 12 years. Mr and Mrs Nowman closed their old stall last week and took three-and-a-half days to move their stock and set up their new premises.
Mr Nowman said: "This new stall is more than double than what I had previously.
"Now we can add more lines and customers can browse around.
"I’m very happy here."
Mr Nowman said he is excited for the future of the town, especially as more of his fellow market traders will be setting up in their new units over the next few weeks.
"It's great to see the market being done," Mr Nowman added.
"And we have the new Marina Centre to look forward to as well. It's great to see all this investment being spent on making the town a better place for everyone."
As well as watches, straps and batteries, Extra Essentials also sell fashion jewellery, hair accessories, scarves and sunglasses. The new stall is open Monday to Saturday, 9am until 4pm.
Other businesses that will be making the move include Unique Sweets, Market Cards and Sean and Lucy Dearn's new chips, pies and peas stall.
Earlier this month, a borough council spokesperson said: “We look forward to the gradual opening of the new building in early May."
