The company will begin moving from the Welsh Bridge, Shrewsbury rooms to their new site in the Battlefield area of the town in February.
The 20,000 sq ft building, next to Shrewsbury Auction Centre, will have two fine art salerooms, dedicated offices, storage space and 110 parking spaces.
David Giles, a director of Halls, who is managing the project, said: "Having outgrown our offices at Welsh Bridge, we are looking forward to moving into a modern building, which is much more accessible to our clients.
"The move will see a major expansion of our fine art department, with a sale calendar to match. Our agricultural and professional departments will also expand in 2013 and there will be a natural synergy by being located on the same site as the auction centre."
Halls' fine art directorJeremy Lamondadded: "The new facilities will allow the fine art department to expand and offer a greater sales programme, with more dedicated specialist sales."
