The E-shaped palace building is located on the east bank of the River Medway close to its meeting with the River Len.
The two-storey central section is constructed of ashlar stonework with a main entrance through a central projecting porch in the north-east façade.
Timber framed wings are at each side.
The roof is clay tiled and two projecting stone-built dormer windows at attic level on the entrance façade are capped with finials.
The south-west façade has windows in a variety of sizes, many stone-framed, and includes a large corbelled and three-tiered and oriel window.

Close to the palace on the south side is the dungeon, a 14th-century stone building with small windows and an early Norman undercroft.
To the north-east of the palace, adjacent to Mill Street and the River Len is the 13th and 14th century gatehouse, a two-storey building constructed of roughly-coursed rubble and timber framing on the east end.
The roof is tiled and a garderobe projects on the north side.

The palace is a Grade I listed building, the dungeon is listed Grade II*, and the gatehouse is listed Grade II and a scheduled monument.
The buildings are surrounded by walls which are Grade II listed.
The Dungeon is on the Historic England Heritage at Risk Register.
