Well-known and long-established Brigg company Thomas Bell & Sons Ltd is seeking permission for a single-storey extension to its existing offices off Bigby Road, near the level crossing.
The firm has told local authority planners it wishes to provide an additional boardroom and extended kitchen due to continued expansion of the business.
Brigg Town Council's Planning & Environment Committee, meeting in the Angel Suite on Monday night (September 24) decided it was "in support" of this application.
Chairman Coun Mike Storey told his colleagues that the extension was required "because the business is expanding."
The Thomas Bell firm, which operates the popular Country Store, can trace its history back to 1878, making it one of the town's most long-established businesses.
The store stocks a wide range of country clothing and footwear, pet and animal food "and all you need for the horse & rider."
Brigg Town Council is also supporting an application to erect a single-storey extension to the side and rear and a two-storey extension to front at 40 Bigby High Road, Brigg.
Meanwhile, in neighbouring Wrawby, permission to erect eight dwellings, including garages and access, is being sought for land adjacent to Ridgeway House, Mill Lane.
North Lincolnshire Council, the local planning authority, is now considering both these applications.
