Prime Cardiff office building up for sale with a £17m price tag

The property investment in One Kingsway is being marketed by JLL

A prime office building in the centre of Cardiff has been put for sale with a £17m-plus price tag.

The freehold interest in the One Kingsway building, which extends to just over 68,000 sq ft of grade A office space across seven floors, is being marketed by property advisory firm JLL on behalf of an undisclosed private charity.

The building, which recently underwent £3m of investment, has a range of occupiers including professional advisory firm PwC, NatWest, the British Council and Avison Young. It generates a rental income of just over £1m a year.

Justin Millett, lead director at JLL’s Cardiff office, said: “We have been very encouraged by the levels of interest for this high profile landmark building. The asset offers strong rental growth potential and an opportunity to drive investment returns through proactive asset management.”

JLL are also the marketing agents for the vacant office space in the building with part of the ground floor under offer and strong interest in part of the sixth floor.

JLL itself did occupy space on the ground floor of the building, but recently relocated to office space – shared with Grant Thornton – at the Callaghan Square development close to Cardiff Central Railway Station

One Kingsway’s biggest occupier in PwC, recently struck a new lease agreement until 2026 – with a break in late 2025.
