Managing director Jonathan Pratt opened the new location last month and will host the first auction at 10am on September 10.
Notable lots in the Antiques and Interiors sale, which is also being hosted online at thesaleroom.com, will include a collection of travelling trunks by French luxury brands Louis Vuitton and Goyard. Estimates on these trunks that are being sold by a noble family, are between £1500 -3000.
Bellmans have been based in Wisborough Green in West Sussex for the past 25 years and Pratt has been managing director for the past 11 years.
They employ around 20 staff as well as a small team at the new auction room in Winchester which they plan to grow.
The company hold regular antiques and interiors auctions offering items including silver, jewellery, Oriental works of art, furniture and garden statuary. They expect to host monthly auctions in the first week of every month at Wisborough Green and in the second week of every month in Winchester.
The two locations will work in close collaboration.
Pratt also works out of a central London office where valuations can take place by appointment.
