Plans for a new gym, sauna and study, to replace dilapidated existing buildings at a ‘landmark’ listed Victorian clifftop house, overlooking Tenby’s North Beach, have been given the go-ahead.

In an application to the Pembrokeshire Coast National Park Authority, Andrew Lewis, through agent Acanthus Holden Architects, sought permission for the erection of three outbuildings at the Grade-II-listed Nyth Aderyn, North Cliffe, Tenby.

The applicant seeks to replace a semi-derelict timber ‘pavilion’ with a gym on the upper terrace, a ‘treehouse’ study on the mid terrace, again replacing an outbuilding in serious disrepair, and a sauna on the lower terrace, also replacing a building in disrepair.

The application, in the town’s conservation area, was supported by both Tenby Town Council and Tenby Civic Society.

An officer report recommending approval said: “Nyth Aderyn was designed in 1883 by the prominent London architect Ernest Newton in the fashionable ‘Queen Anne’ or ‘domestic’ Revival.

“Extended under Newton in 1893, the house is characterised by red clay tiled roofs and walls, bay windows with small-paned casements and (prior to listing) fine tall brick chimney stacks.”

It added: “The proposal is regarded as improving the setting of Nyth Aderyn, replacing poor buildings in varying states of repair. The terraced garden occupies a prominent section of the North Cliff, readily visible from the south, including the harbour area. The siting, scale, design and finishes of the buildings acknowledge their fine setting.”

It went on to say: “Nyth Aderyn is noted as a landmark building in the Tenby Conservation Area SPG, the house and its cliff-top grounds prominently visible from the harbour area.

“The proposal is regarded to both preserve and enhance the appearance of Tenby Conservation Area. The proposed buildings are modest, well-screened by existing trees, replacing existing structures of no intrinsic interest.”

The application was conditionally approved by park planners.
