There has been no application to have the Oasis centre delisted, the organisation which operates the list has said.

Historic England confirmed that it has not received a request to delist the iconic dome, after it was confirmed that councillor would attempt to do this to get the former leisure facility back up and running.

The Conservative councillors who run Swindon Borough Council announced last month that the administration would attempt to have the Oasis delisted despite it only being granted the protections at the start of the year.

They say it’s necessary to make renovation easier and prevent the 1976 building from becoming a “modern-day Mechanics’ Institute”.

Although the decision on listing and de-listing will be taken by the secretary of state for digital, culture, media and sport, currently Chippenham MP Michelle Donelan, the Swindon-based heritage organisation said: “We would only take an application forward for de-listing if substantial new information about the lack of special architectural or historic interest came to light to justify a reassessment."

In a post on its website Historic England gave reasons why the building had been listed for its architectural importance and distinctiveness: “The swimming pool is the best and earliest example of the newly developed building type, which went on to gain huge popularity in the 1970s and ‘80s, marking the cultural shift from swimming for fitness to swimming for fun. Most of the early examples of these buildings have now been lost to redevelopment.

“The 45-metre swimming pool dome is an architecturally striking and technically accomplished structure. Externally, it rises from a grassy bank, while internally, the aluminium spaceframe provides a dramatic setting for the pool and is well-suited to its use, having withstood the corrosive pool environment.

“While the glazing has been replaced, the architectural concept remains apparent. It was carefully planned by the architects to create a fun and attractive leisure space, and the key features of the concept survive, including the free-form lagoon pool with its sloping, beach-like approach, and the infrastructure for a tropical planting scheme. Its design remains synonymous with the early development of the leisure pool.

“The listing has been limited to include only the domed pool. The dry-sports side of the building; the waterslides, their launch tower and splash pool; the linking entrance block; and the service structures are not included in the listing.”
