Corn Store, 11 Market Street, Moneymore, Magherafelt, Co Londonderry, BT45 7PE

This is a fine example of early Victorian ambitious industrial architecture. The corn store, erected between 1835 and 1839, was designed by William John Booth, the Draper's Company Architect, and built as part of a market complex completed in 1839. The contractor was Daniel Magee, acting on the proposal of George Bridger, Clerk of Works and builder. Contemporary records praised it as "a very handsome and capacious grain store" and "a magnificent new corn store", describing the whole complex as "extremely well executed" with "a most striking and ornamental appearance".

The building is a nine-bay, three-storey structure with basement, featuring a slated gabled roof with balcony access. It retains remarkable detail of construction and provides a striking functional contrast to the Neo-Classical design of the adjacent front building facing the High Street.

The west elevation overlooks the market yard. The ground floor has a central double timber-sheeted door positioned between two piers of ashlar sandstone, with two wide bays on each side divided by further wide ashlar sandstone piers. These piers support deep beams that span between them and carry an access balcony at first floor level. Set back the depth of the balcony, the rising walls feature a wide timber door and small window in red brickwork, each giving access to individual stores. At the south end, a shed abuts against two bays and two storeys. The first floor has two doors between ashlar sandstone piers providing access from the central stairway to the balcony. To north and south, there are two single segmental-arched doors and two likewise-arched windows each serving four separate stores of equal size. This arrangement is repeated on the second floor. The balconies appear to be supported by cantilever beams trimmed at the outer edge with iron angle. The open balustrade is formed with angle iron creating a series of saltires with a metal handrail. The inner wall is faced with coursed white limestone. The access balconies terminate against the gable wall. The roof overhang with deep fascia extends to provide cover to the balcony. The balcony construction is now almost ruinous, as are the gutter and end downpipes. The roof is covered in natural slates. The north gable is faced with coursed white limestone and sandstone quoins, whilst the south gable is smooth rendered, presumably over coursed white limestone.

The east elevation has a central arched timber doorway with a smooth wide sandstone surround and peacock-tail fanlight, over two small shuttered windows at first and second floor. The next bay to north and south has a single small shuttered window at each floor. The next two bays in both directions have double timber-sheeted doors at first and second floor with a high-level shuttered window beneath. In the end bays there are again small shuttered windows at first and second floor, with a blank larger opening at ground level. This wall is built of coursed white limestone with sandstone quoins and shallow sandstone segmental lintels over windows. Grills at ground level ventilate the basement area. The building has a natural slated roof and stone plinth.

The corn store is situated to the east side of the market yard with additional road access to the east from Market Street. The market yard formerly contained a weighbridge at its centre, now demolished. The building has survived many years of comparative disuse. It is now the property of John Glover Ltd and forms part of a Townscape Heritage Initiative under the Moneymore Heritage Trust Ltd, with proposals for conversion into apartments.
