Cardiff (Wales Times) November 06, 2026 — County Hall has moved closer to delivery after the final design of the new council headquarters was settled, but the scheme has drawn a divided response from members of the public.
As reported by Kieran Molloy, Local Democracy Reporter for Nation.Cymru, the final decision has been made on what uk/local/cardiff/">Cardiff’s new £60m county hall will look like, although not everyone is happy with the outcome. The proposal is located at Atlantic Wharf in Cardiff Bay, close to the existing County Hall and the site of the city’s proposed indoor arena.
What Will the New County Hall Look Like?
The development has been described in planning documents as a “dual-use civic ensemble”. It would bring together a contemporary council office building and a cultural destination for Wales Millennium Centre known as Capella.
According to details reported by Yahoo News, drawing on the planning application submitted by Goldbeck Construction Ltd, the design is intended to create a deliberate contrast between the two main elements: a transparent, gridded office building and a solid, self-contained theatre. The application describes the pairing as reflecting “complementary modes of occupation”: productivity and focus alongside immersion and collective experience.
Cardiff Life reported that the proposed replacement is a six-storey building and forms part of a wider Atlantic Wharf scheme beside the new arena. The council’s own materials describe the new Core Office building as 120,000 sq ft, smaller than the existing County Hall and designed to support a more modern, hybrid model of working.
Why Is Cardiff Replacing County Hall?
The council argues that the existing County Hall, built in the late 1980s, has reached the end of its operational life. In a March 2026 report, Cardiff Council said the building had been assessed as a high-risk liability for several years because of mounting structural deterioration, spiralling maintenance backlogs and the increasing likelihood of building failure.
The authority estimated in 2023 that around £140m of work would be needed simply to keep the current County Hall operational because of its size and age. By March 2026, the council said refurbishment estimates for the existing building had grown to £180m and would require staff to relocate for an extended period.
Cardiff Council leader Cllr Huw Thomas said the condition of the existing core office estate had reached a point where the risks and costs of maintaining County Hall were “simply unsustainable”. He said the completed Pre-Contract Service Agreement stage gave the council a “clear, fixed-price route” to deliver a smaller and more energy-efficient building.
Cabinet Member for Investment and Development Cllr Russell Goodway said County Hall had “reached the end of its operational life”. He added that the longer the council remained in the building, the greater the £140m-plus maintenance backlog became, with the added risk that a failure of critical systems could force an emergency relocation at unplanned cost.
Why Are Some People Unhappy?
The design has attracted criticism from people commenting on the planning application. As reported by Yahoo News, one anonymous commenter said the building was “closer to a generic commercial office development than a building that should represent Cardiff and its public institutions”.
The same commenter described the proposal as “exceptionally bland, lacklustre and unimaginative”, and said they were “particularly disappointed by the apparent lack of ambition in the design”.
Another commenter said they had originally been “genuinely excited” by the regeneration, but believed the original ambition of the proposal had since been lost. They wrote that the current proposal appeared to move “considerably further towards an imposing, institutional and office-led building”, with surrounding open space becoming secondary to the building itself.
That commenter also raised concern about density in the area, saying that in a part of Cardiff already becoming increasingly dense, the approach was “precisely the wrong direction”.
These objections were reported in coverage of the planning application, including by Nation.Cymru’s Kieran Molloy, whose report framed the response to the finalised design as mixed rather than uniformly supportive or hostile.
What Has Cardiff Council Said?
Cardiff Council declined to comment in detail while the planning application was live. A council spokesperson said:
“As this is a live planning application that has been recently submitted to the Planning Authority, it would be inappropriate to comment until the application has been determined.”
The spokesperson added that comments could be submitted online or by email to the council’s Development Management team.
The council has previously said the replacement office is intended to reduce long-term costs, lower carbon impact and provide a modern workspace. It also says the scheme would support the wider regeneration of Atlantic Wharf by delivering modern infrastructure, shared public-realm improvements and a coordinated programme of remediation and redevelopment.
How Does Capella Fit Into the Scheme?
Capella is the proposed cultural element of the development, associated with Wales Millennium Centre. The planning application describes it as a “cultural destination”, while the council has referred to a Capella Production Studio partnership as part of the wider Atlantic Wharf regeneration.
The council has said the Agreement for Lease with Wales Millennium Centre for the Capella Production Studio would be finalised as the project progresses. The combined office-and-cultural proposal is therefore not solely a council headquarters scheme; it is also intended to contribute to Cardiff Bay’s cultural and visitor offer.
What Happens Next?
Cardiff Life reported on 5 November 2026 that the six-storey replacement County Hall and the Wales Millennium Centre’s Capella venue had been recommended for approval and were due to go before Cardiff’s planning committee that day.
The council had previously said that, if its Cabinet approved the recommendations, it would enter a Development Agreement for a turn-key 120,000 sq ft office building and submit a planning application. Detailed fit-out planning would then follow, ahead of a future Cabinet report.
The project is also linked to the proposed Indoor Arena. The council said maintaining alignment with the arena was essential because delays could remove opportunities to share costs for service diversions, groundworks and public-realm improvements. It also identified a cost-capped temporary link road solution of £1.9m to maintain arena access.
Background of the Development
County Hall has been Cardiff Council’s headquarters since the former South Glamorgan County Council building became the authority’s main office. The current building was designed by J.R.C. Bethell, the County Architect for South Glamorgan, and built between 1986 and 1987.
It was constructed on land beside the disused Bute East Dock in Atlantic Wharf, at a time when the surrounding area contained substantial post-industrial dereliction. The building was officially opened by Lord Callaghan in October 1988 and later won the National Eisteddfod of Wales Gold Medal for Architecture in 1991.
The Twentieth Century Society has recorded that the building was designed with a low-rise quadrangle form and was intended to be human in scale, welcoming to the public and possessing civic grandeur. The society also notes that Cardiff Council gave outline planning permission in March 2022 for the wider redevelopment of the Bute East Dock and Atlantic Wharf site as part of a masterplan including a new indoor entertainment arena.
Cardiff Council’s case for replacement intensified after the Covid-19 pandemic, when the authority reviewed its working practices and concluded that refurbishing County Hall was no longer financially viable. The council said a new building offered the cheapest long-term solution, the lowest carbon impact and a workspace better suited to modern service delivery.
Prediction: What Could This Mean for Cardiff Residents?
For Cardiff residents, the immediate effect is likely to be continued change around Atlantic Wharf. If approved and built, the scheme would replace a large, ageing civic office with a smaller headquarters while adding a cultural venue and contributing to the wider regeneration of Cardiff Bay.
Council taxpayers may pay particular attention to the financial case. The council says the new building is intended to reduce long-term maintenance exposure and avoid the estimated £140m-plus backlog associated with the existing County Hall, although the project itself carries a reported £60m cost.
For people who live, work or visit Cardiff Bay, the development could alter the character of Atlantic Wharf. Supporters of the project may see a more efficient civic building and new cultural facilities; critics have concerned themselves with the architectural quality, public space and increasing density in the area.
For council staff, the proposal points towards a smaller, modern office designed for hybrid working. For local businesses and creative organisations, the council argues that the scheme could support new activity through the Capella partnership, increased visitor numbers and employment opportunities connected to the wider arena and regeneration programme.
The most important next milestone is the planning committee’s decision. Its outcome will determine whether the finalised design can proceed, and whether the objections raised about the building’s appearance and impact on public space will influence any changes before construction.
