Sleaford Railway Station

Sleaford Railway Station was built in 1857 for the Boston, Sleaford and Midland Counties Railway, and extended in 1882 for the Great Northern and Great Eastern Joint Railway. It is constructed of coursed rubble and brick with ashlar and brick dressings, and has slate roofs.

The entrance front features a central, recessed, four-bay, 1 1/2-storey building in stone, with ashlar coped gables, kneelers, an ashlar gable, a brick gable, and an ashlar ridge stack. Ashlar quoins and a plinth are present. The former off-centre entrance bay is slightly advanced, with a plain sash window in a chamfered surround with a Tudor hood, and a two-light chamfered mullion window below with original patterned glazing, set within a through eaves gabled dormer decorated with three ornate finials. Either side of this are single, two-light chamfered mullion windows with original patterned glazing, each above a single, similar two-light window in a through eaves gabled dormer. To the right is a slightly advanced bay with a large square bay window with plain sashes, and above, a two-light chamfered mullion window with plain sashes in a through eaves gabled dormer. Single-storey brick additions, with shallow pitched roofs and deeply overhanging eaves, are located either side of this, each consisting of eight irregular bays. The right-hand addition is topped by a square wooden lantern, while the left-hand addition incorporates a single, 1 1/2-storey staircase block leading to the footbridge. Both wings are articulated with irregularly spaced glazing bar sashes and plank doors with glazing bar over-lights.

The platform front has a similar earlier and taller stone central section with later brick wings, and a deep wooden canopy supported on ornate columns and brackets. This is joined by an enclosed wood and iron footbridge to the waiting rooms on the western platform, which are of panelled wooden construction with all-round wooden canopies supported on ornate iron columns and brackets.
