Description

Telford's Tower is a square tower with three storeys above a basement, accompanied by a single-storey rectangular range to the east, creating an overall L-plan. The building features stucco elevations and slate roofs, with the tower section having a pyramidal roof that includes feathered eaves and an urn finial. On the south side of the tower, which faces the village, there is a canted oriel on the ground floor with a sloped metal roof, containing a central 6-pane window flanked by 3-pane outer lights. Above this oriel, there is an 8-pane vertical window with external wooden slatted shutters and a shallow segmental arch above it. The upper storey is slightly recessed and has a 6-pane window, with similar windows on the side elevations.

The adjoining block features steps leading up to an arched entrance on the left, which has a multi-pane glazed door. To the right, there is a Venetian window, and on the eastern gable end, there is a blind recessed oculus above. To the right of this block, there is a rendered and tile-coped wall that steps up over two round-headed arches with volutes on the sides. To the right of these arches is a larger rusticated arch, which is topped with stone Royal arms featuring lion and unicorn supporters. A short link section connects this structure with the adjoining Unicorn.
