The showground, which is set in the 140 acre leisure venue, has space for up to 100 traders and will be launched on Monday, May 10, running from 6am to 2pm.
Former pub landlady Mrs Lewis said fulfilling their dream to turn their hobby into a business began two years ago.
“In 2019, after a spell in the pub trade where we ran Framlingham’s Castle Inn for five years, Alan and I opened an antiques centre in Diss. We are both keen antique and vintage collectors and thought we would pursue a long-held dream to turn our hobby into a profession.
“We were thoroughly enjoying helping customers to find the perfect pieces for their collections and home interior refurbishments when the pandemic arrived in the UK.”
