Cardiff Bay (Cardiff Daily) January 26, 2026 – iungoworks has unveiled ambitious plans to expand West Bute House, transforming the historic Grade II-listed property into a comprehensive 20,000-square-foot commercial quarters hub for innovative businesses in Cardiff Bay. This next phase follows an exclusive private acquisition of 36-37 West Bute Street, introducing premium facilities amid the area’s rich industrial legacy. The development underscores a fusion of 18th-century heritage and contemporary workspace demands.

What is the History Behind West Bute House?

West Bute House, situated at 33-37 West Bute Street, comprises five terraced plots once integral to the Britannia Buildings Development. Originally constructed in 1783, these Grade II-listed structures served as the epicentre of Cardiff’s Industrial Revolution, functioning as a vital coal shipping hub. For over a century, the buildings remained separated until iungoworks reunited them through sympathetic redevelopment.​

As detailed in the announcement covered by Wales247, the site now forms an integrated four-storey workspace that preserves its 18th-century character. iungoworks, founded by Jessica Leigh Jones and Tom de Vall through their iungo Solutions venture specialising in digital and green skills training, acquired the former coal shipping company building in the Mount Stuart conservation area last year. This restoration, reported by Business News Wales, converted it into high-spec open-plan coworking with serviced suites and meeting rooms.

The building’s location in Cardiff Bay’s commercial district highlights its evolution from industrial past to modern professional venue.

What Expansion Plans are Set for 2026?

The 2026 expansion introduces ten new high-specification private offices accommodating two to ten desks, now available for securing. A Private Members’ Gym will open in July 2026, followed by a unique underground café-bar in the restored historic basement by December 2026, evoking the building’s industrial heritage.​

These upgrades, as announced via Wales247, cater to modern workstyles within the 20,000-square-foot complex. The café-bar pays direct homage to the site’s coal shipping history, enhancing the atmospheric appeal. Private offices blend seamlessly with existing facilities, prioritising flexibility for start-ups, SMEs, and larger operations.

What Amenities Does West Bute House Offer?

Tenants enjoy a fully inclusive community environment with superfast broadband, bicycle racks, showers, meeting rooms, rooftop event spaces, and unlimited bean-to-cup coffee. The property boasts 21 self-contained office suites, premium coworking spaces, and virtual office options.​

Earlier coverage by Business News Wales on the initial launch emphasised flexible solutions for remote workers, scale-ups, and satellite offices. Jessica Leigh Jones highlighted virtual memberships offering company addresses, mail forwarding, and day-pass discounts. Late-evening access supports non-traditional hours for creatives.​

How Much Do Workspaces Cost at iungoworks?

Private office suites commence at £650 per month on a fully inclusive basis, while coworking memberships start at £120. Group CFO Tom de Vall, as quoted in Wales247, confirmed these rates while inviting reputable organisations to join.​

This pricing supports forward-thinking businesses seeking value in a heritage setting. The waitlist for Phase II private offices is open, with viewings encouraged to showcase the blend of history and utility.​

What Do iungoworks Leaders Say About the Project?

Jessica Leigh Jones MBE, Group CEO for iungoworks, stated to Wales247: “West Bute House is more than just an office building, describing it as a commercial quarter designed to mirror the success of the organisations that call it home. By reuniting these historic plots, iungoworks is creating a workspace that respects Cardiff Bay’s heritage while providing the high-specification environment necessary for the businesses of tomorrow.”​

Tom de Vall, Group CFO, added: “iungoworks is currently seeking reputable, forward-thinking organisations to join its growing community… Interested parties are invited to book a viewing to experience the blending of historical charm and modern utility firsthand.”​

From the prior launch reported by Business News Wales, Jessica Leigh Jones said: “After years of working in bedrooms and at kitchen tables during Covid, people are craving structure, routine, and separation between work and home and coworking at iungoworks offers all that, minus the commute of a traditional office. We’ve designed iungoworks to be more than just a place to work, it’s a space where collaboration and creativity can be sparked and meaningful connections can be made. We’ve blended the historic character of the building with cutting-edge facilities and we are really proud to have created an environment that empowers individuals and businesses to grow together. One of the things that sets us apart from other coworking spaces is our flexible approach to working. We stay open late into the evenings to encourage creatives to use the space in ‘non-traditional’ working hours. We have also received interest in our virtual memberships, which provide people with a company registered address, mail forwarding and discounts on coworking day passes.”​

Tom de Vall remarked:

“Coworking is about more than shared desks. It’s about shared energy, ideas and ambition. This space isn’t just about where people work, it’s about how they work together. At iungoworks, we’re proud to build a community where people can inspire one another and turn bold ideas into real impact. Honouring the industrial legacy of the Grade II listed former coal shipping building we call home, we’ve crafted a sleek, contemporary approach to business, one that remains mindful of its historic surroundings in the heart of our capital’s commercial district.”​

Why is This Expansion Significant for Cardiff Bay?

This project revitalises a key heritage asset in Cardiff Bay’s Mount Stuart conservation area, fostering economic growth through premium workspaces. By accommodating diverse businesses, it bolsters the region’s status as a hub for innovation post-pandemic.

iungoworks’ vision, rooted in iungo Solutions’ skills focus, positions West Bute House as a model for heritage-led regeneration. The expansion arrives amid rising demand for flexible, community-oriented offices blending history and modernity.

When Will the New Facilities Open?

New private offices are available immediately for securing, ahead of the July 2026 gym launch and December 2026 café-bar reveal. This phased rollout ensures seamless integration into the existing operations.​

Business News Wales noted the initial coworking launch in June 2025, setting the stage for this growth.
