Cardiff's former Debenhams site still a building site

More than five years after Debenhams in Cardiff closed, the former flagship store remains an unrecognisable building site, with fresh pictures showing little progress since February 2026. The site, once one of the capital's busiest shopping destinations, has been reduced to little more than rubble since the store shut in 2021.

A flagship store reduced to rubble

The department store was built in 1981 and opened the following year as one of the cornerstones of the original St David's shopping arcade. The vast shopping area, spread over several floors, was open for 39 years before the 242-year-old chain went into administration in 2021.

Reflecting the struggles faced by retail in recent years, the site remained empty for several years before the owners of the St David's shopping centre, Land Securities, submitted plans in August 2024 to demolish the site and replace it with a public square.

Delays to the City Square development

Construction of the square was expected to begin in September 2025 and set to finish in June 2026. Landsec said this was "subject to approval and no delays" with the park then expected to open to the public in summer 2026. As of October 2026, fresh pictures reveal that the former store remains a building site.

A spokesperson for St David's Cardiff - which owns Land Securities - said: "We're currently taking the necessary steps to move into the last stages of demolition, including recently securing planning permission for these final works.

"The demolition process for the City Square development has taken longer than expected, as is common with sites of this scale and complexity, and we look forward to sharing more details on next steps for the space in due course."
