18 Main Street, Limavady, Co Londonderry, BT49 OEU

This is a four-storey Georgian townhouse with a shop on the ground floor, facing south-east onto Main Street in Limavady. It is located at the north-eastern end of a group of three similar houses and likely dates from the second half of the 18th century, although it was probably constructed between 1820 and 1839. It is shown on an Ordnance Survey map from 1831.

The building has a brick facade with a rendered ground floor. It features a slate roof, cast iron rainwater goods, and large brick chimneys situated on the apex over the gable and party wall. The windows are Georgian sash windows, two to each floor, diminishing slightly in height on each level. The first and second floors have twelve panes each, while the third floor windows have nine panes. A panelled door with a rectangular fanlight is located at the south-east corner of the ground floor, recessed within a plain plaster surround, with three concrete steps leading up to it. A large window extends across most of the ground floor facade, aligning with the top of the fanlight. Small applied timber pilasters flank the sides of the window, designed in proportion to the entablature above, which is modelled after that of number 16 Main Street (HB02/12/006A). There is a concrete cill to the window and three mullions. The north-east gable is rendered in sand cement, apart from the brick chimney. The rear elevation includes a projecting return and one remaining Georgian sash window. Behind the main building is a two-storey brick former stable block, which is currently vacant.

The shopfront is new, and the internal layout has been altered, along with the rear of the property. The amount of historic character that survives is now reduced. In 1973, the building was occupied by William J G Seeds and Company. A two-storey building adjacent was demolished in the early 1980s to provide vehicular access to the Roe Fold Sheltered Housing Scheme behind the Town Hall. The building was delisted on February 1st, 2001.
