The warehouse space in the Murray Street precinct, next to the Australia Post branch, is filled with thousands of antique furniture and collectibles.

The pop-up shop has been opened for more than a year and its impending closure signals Mr Gilfillan's desire to move on and focus on his passion.

"I've got too many projects and this has to go ... I can't manage a shop and I can't really focus on what I want to do," he said.

"I bought the hall in Uranquinty about five years ago and I wanted a studio for painting ... and so what's not sold and what I don't donate, I'll open up my shop back there."

Mr Gilfillan plans to turn the area into a function or venue space, with a Japanese tea house, painting studio and historical stables for the shop.

The antique dealer said the retail environment has become increasingly challenging, especially with the multiple forms of advertising.

"There's a lot of things against us ... the drought, money is really tightening, there's no spending," he said.

"There's too many forms of advertising and that's half the issue ... TV, radio, newspaper then, it's Facebook, Etsy, Ebay and Gumtree - even Instagram is big now.

"My problem is, I like to think young but my brain won't work in that sphere now ... I don't have time to do multimedia."

Mr Gilfillan said in order to make the business more viable, he would have to put at least half of his stock online.

Among the online retailing challenges, it has also been hard to compete with the charity op-shops.

"We find that we don't sell anything good; it's very hard to sell nice quality things," he said. "

We compete in Wagga with about 10 op-shops ... I'm not an op-shop, I'm a private shop, I pay for my stock - they get their stock for free.

"People are more welcoming to give money to a charity rather than a shop."

The Morgan, Murray, Docker and Forsyth streets vicinity has been thrust into the spotlight in recent weeks following a planning proposal to amend the Wagga Local Environmental Plan.

The proposal, led by property firm Damasa, has copped intense public scrutiny with Central residents arguing this could potentially lay the foundation for future development.

Mr Gilfillan said his exit from the area has nothing to do with the future plans.

"Everyone says I'm moving because [the Donebus family] is doing the development," he said.

"All development is good ... I'm just worn out. The Donebus' have been absolutely fantastic to me."
