A call to replace a Pembrokeshire village school classroom that had reached the end of its life with a modern facility has been given the go-ahead by county planners.

In an application to Pembrokeshire County Council, the local authority itself, through agent Williams-Architects Ltd, sought permission for the erection of a new modular classroom building at the site of Llandissilio’s Ysgol Brynconin Welsh Medium 3-11 school, along with the demolition of the existing modular classroom building.

A supporting statement said: “In addition to the main school building, some classroom and library facilities are located in a prefabricated hut within the school grounds constructed under the historical HORSA programme.

“Despite various upgrades over its lifespan including insulation and new windows, the building is no longer fit for purpose, and a replacement is required to ensure the school can continue to provide its pupils with modern, suitably equipped and compliant facilities that enable high quality education.”

HORSA buildings were originally designed as temporary structures, typically constructed using prefabricated concrete, timber, and steel to facilitate rapid assembly.

Although intended for short-term use, many HORSA buildings have remained in operation for decades. Over time, these structures have surpassed their intended lifespan, leading to significant structural issues, such as weakened frames, deteriorating roofs and external facades.

The statement added: “The primary use of the replacement building will remain as currently; it will include a single classroom alongside a multifunctional space which will be used as a library, staff and group room as required. It will also include an additional toilet, new accessible toilet, a cleaners’ store and formal classroom storage.

“The intention of the proposed building is to replace an existing classroom facility which is no longer fit for purpose, and whilst a simple replacement will significantly improve the day-to-day experience of the staff and pupils who currently use this building.”

An officer report recommending approval said that, while the proposed replacement building would not result in any greater impact on the visual amenity in terms of its design, scale and overall appearance, the proposal includes the demolition of an existing building which could have an impact on the local amenity during the demolition process.

It said that, since local concerns were raised, a Demolition and Construction statement has set out the proposed demolition methodology and construction process, including details of the sequence of works, hours, and anticipated timeframe, and it is considered that the proposed demolition and construction “will have no significant detrimental impact upon the locality amenity”.

The application was conditionally approved.

Back in July 2025, members of the council’s Cabinet backed approval for a new modular building at Ysgol Brynconin, members hearing that “the external structure has rapidly declined, with the render board failing and allowing water ingress into the areas of external wall insulation”.
