Withersdale Street is a village in the civil parish of Mendham, in the East Suffolk district,[1] on the Norfolk/Suffolk border, in the Waveney Valley.

To the west of the village lies Mendham Priory, an early 19th century neo-classical mansion, with a Doric style porch, whilst to the east, the Red House, a later Georgian red brick building also mentioned by Pevsner, faces towards the new village hall and overlooks the playing field.

Mendham Priory also survived a nearby bomb blast during the Second World War which is said to have lifted the entire roof of the conservatory without breaking a single pane of glass.

Grange Lodge was the old police station, whilst the Old Post House originally had petrol pumps outside.

Two new storage buildings were added to the village hall site in 2015, together subsequently with two boules boulodromes or pitches.
