[1] In the early 20th century the local council was based at municipal offices in "Clattern House", a mansion which had originally been built as judges' lodgings in 1811.

[6][7] It is a neo-Georgian red brick building with Portland stone dressings and tiled roof, laid out to a semi-circular plan.

[1] To the centre of the semi-circular elevation is a massive square tower with a low octagonal spire and fluted corner pinnacles.

Above it is a two-storey, round headed window set in an open pedimented stone niche with simplified Corinthian columns rising from a corbelled balcony.

[1] Inside, there is a marble lined circular entrance hall, and a central staircase with original opaque glass semi-spherical lamps.
