[3] The new building was designed by Owen Browne Carter in the Italianate style, built in yellow brick with stone dressings at a cost of £4,000 and was completed in 1838.

The central section of three bays featured a portico formed by four Tuscan order columns supporting an entablature, a cornice with wide eaves and a modillioned pediment.

[4] Describing the front of the building, The Gentleman's Magazine said that Carter had "endeavored to avoid the flimsy effect of the modern Grecian school, and to keep in view the more legitimate style of design inculcated by Palladio in Italy, and at home by our own countrymen, Jones and Wren.

"[5] The use of the building as a corn exchange declined significantly in the wake of the Great Depression of British Agriculture in the late 19th century.

[4] A major programme of works, costing £7 million, to convert the building into a "Discovery Centre" was completed in February 2008.
