The following text is from the original listed building designation:
LYDD
TR01NE DUNGENESS 845/6/10005 Dungeness 26-MAR-03 Lighthouse
GV II* Lighthouse. Designed 1957, built 1959-60. Architects: Ronald Ward and Partners in association with Trinity House. Builders: Taylor Woodrow Construction. The construction comprises 21 concrete drums, each 5ft high, surrounded by a white concrete spiral ramp enclosing the machine room and lifted into position by a specially designed crane. High tensile steel wires were then run through the walls from top to bottom and post-tensioned using the Freyssinet system to provide the strength required to resist 80 mph gales. There is extra strength towards the base of the tower by having extra prestressing cables rather than the traditional taper, giving it a more sophisticated and elegant form. The old lighthouse was originally banded black and white (now black to show that is no longer an active Aid to Navigation), and this design was repeated in the new one by making the drums in black and white coloured cement and special aggregates, although it is now also painted black and white. The tower is 130ft high and 12 feet in diameter, with walls only 6 inches thick. The six bands of perforations towards the top contain the loudspeaker units of the fog signal (no longer functioning since a new system was provided in 2000), and give a rich textural contrast. The interior contains an elegant cantilevered spiral staircase, slightly kinked on plan and with a steel handrail, which leads to the miniaturised 134,000 candlepower lantern (installed 2000, and with a range of 21 miles). There is no need at Dungeness for living accommodation, and all the machinery and electronics are housed within the spiral ramp at the base. The new equipment installed in 2000 has updated the building sympathetically, but is not itself of special interest.
`The first major new lighthouse to be built in Britain for fifty years' (Architects' Journal, 18 August 1960), it replaced the old Dungeness lighthouse, the light from which was to be obscured by the atomic power station built nearby. It cost c.£35,000. The lighthouse was officially opened by the Duke of Gloucester on 29 June 1960, within a year of construction work beginning. `The new Dungeness lighthouse offers a high degree of sophistication with a degree of visual appropriateness comparable to the best work of the past' (Architectural Review, September 1960).

Description from record TR 01 NE 204 :
The construction of Dungeness A power station in the 1950s obscured the old (1904) lighthouse and the new one, sited closer to the shore, was completed in 1961. Constructed of 21 pre-cast concrete ring sections and held by tension cables running vertically. This construction gave a slenderprofile to the 140' tower, set on a 2-stage base with external spiral acces stair. The light was the first to use a xenon arc lamp but this was later replaced by a more effective sealed beam unit with a range of 27 miles. For horn loud speakers are set into the upper part of the tower in a grid pattern of indetations just below the slightlt flared upper section. (1)
