Cullercoats Radio Station, Brown's Point

Cullercoats Radio Station, located at Brown's Point, is a wireless telegraphy station built in 1906 by the De Forest Company for Marconi. It was extended around 1930 with a new wireless station building for HM Coastguard. The original 1906 building is made of colourwashed brick and features a Welsh slate roof with cusped bargeboards. It has a rectangular plan and includes segmental arches over two horned six-over-six pane sash windows on the south elevation and one on the north elevation, located to the left of a later 20th-century door. The entrance is situated in the west gable wall.

To the west is the 1930 wireless station, which has rendered brick walls and Westmorland slate roofs, with a stack at the rear left. This building is designed with two end blocks, each topped with a hipped almost pyramidal roof, flanking a central spine wing. It is a single-storey structure. The west elevation features two eight-over-fourteen pane sashes in each end block, with transomed casement windows on the returns facing the central spine, which has the main entrance set in a hipped porch. The other elevations have similar fenestration, including a glazing-bar overlight above double doors in the north elevation and a projecting later 20th-century porch on the south.

This site is an exceptionally early and well-preserved example of a building associated with the initial development of radio telegraphy. The 1906 building represents the first phase of wireless telegraphy's significant contribution to the scientific and technical advancements of the 20th century. It stands in close proximity to the larger station from around 1930, which exemplifies the thoughtful architectural treatment of government-owned utility buildings during the inter-war period, particularly through its careful use of materials like Westmorland slate.
