Seaspray

House, built around 1870 for the Grant-Thorold Estate, with later 19th and early 20th century extensions and subsequently subdivided into two houses. The building is constructed of red brick with a pantile roof and is designed in the 17th-century Dutch style. It has an L-shaped layout, comprising a two-room central lobby-entry front with a central entrance porch, and a single-room wing to the rear left.

The exterior is single-storey with an attic, featuring two windows. A chamfered brick plinth runs around the base. The enclosed porch has a blocked chamfered four-centred arch flanked by small 1/1 sash windows, with a single-pane window above the door set within a shaped gable containing moulded brick kneelers, an ovolo-moulded cornice, and coping. The left and right returns of the porch have two-pane windows. The main range to the right features a dummy window with markings indicating a intended three-light casement window with ten panes to each light. To the left is an inserted flush-panelled door with a chamfered wooden lintel, and a 20th-century casement window with glazing bars set within an original window opening. All windows are set within chamfered reveals, have chamfered brick sills, and are topped with hoodmoulds. There is a moulded brick eaves cornice. The shaped gables have moulded brick kneelers, cornices and copings, mirroring those of the porch. A corniced axial stack incorporates three octagonal shafts. The gable ends on the left and right each have a single three-light window to each floor with three panes to each light, within similar surrounds to those on the front. The rear wing has a similar single ground-floor window, a stepped and moulded brick eaves cornice, and an ogee-shaped gable with an end stack featuring a chamfered shaft.

The interior was not inspected during the listing process.

Seaspray is one of a series of estate houses built in Old Clee for Alexander Grant-Thorold of Weelsby Old Hall, designed in a style mirroring that of nearby Clee Hall Farmhouse.
