Boat House Known As Water House

The Boat House known as Water House is a building that was originally constructed as part of the landscaping for Redgrave Park Estate, designed by Capability Brown for R Holt around 1766 to 1770. It later served as a gamekeeper's cottage. The structure is made of white brick and flint with stone dressings, and has later additions of red brick. It features a black glazed pantiled roof and has a rectangular shape with a lean-to added on one side.

The building stands two storeys tall, with the gable end facing the former Redgrave Hall, which has been demolished. This facade includes an entrance with a half-glazed door and a gauged brick flat arched head, above which is a string course and a blocked lunette set within a relieving arch. The exterior of this facade displays banded rustication, combining flint rubble with rendered bands, topped by a moulded pediment.

To the left, the early 19th-century lean-to also features rusticated flint. The symmetrical three-bay right return, facing the lake, is entirely made of white brick, with gauged brick flat arched heads on the ground floor, stone sills on the first floor, and dentilled timber eaves. The left return of the lean-to is constructed of flint and includes a ground floor two-light casement window and a first-floor two-light glazing bar horizontal sliding sash. The rear of the building is made of red and white brick, with a door leading into the lean-to, and features gauged brick heads on the ground floor, with original wallplates exposed. The roof was raised in the late 19th century, adding red brick above the original roof line.
