Chapman Taylor completes contemporary Cat A+ fit-out at 5 Callaghan Square, Cardiff
Chapman Taylor has completed the transformation of an open-plan office suite at 5 Callaghan Square, Cardiff, into a vibrant, contemporary Cat A+ workplace designed to re-energise one of the city’s most prominent business addresses.
The 954m² (10,268ft²) space has been reimagined as a flexible show suite, demonstrating how creative and sustainable design can breathe new life into existing office environments. The refurbishment showcases how the entire floorplate can be adapted to future tenants’ needs, offering an inspiring, ready-to-use workplace that balances flexibility with character.
The design replaces the former maze of partitions with a light-filled, inclusive and adaptable environment that celebrates openness and collaboration. The arrival space dispenses with the formality of a traditional reception desk, instead offering a hospitality-inspired welcome area. Carefully defined zones provide spaces for meetings, focused work and social interaction, while a central teapoint acts as the social heart of the suite.
Sustainability was integral to the approach. The project reuses the existing structure and raised access floors, removes unnecessary suspended ceilings to improve daylight and spatial quality, and uses durable, renewable and recyclable materials such as Foresso wood-chip worktops. New energy-efficient lighting and adaptable layouts further enhance environmental performance and reduce future waste.
The Cat A+ fit-out has significantly enhanced the building’s market presence, allowing prospective tenants to easily envision their own identity within the space. Since completion, the scheme has attracted strong interest and has been described by the client as “the best in the Cardiff market.”
Chapman Taylor delivered the architectural design in collaboration with PAC 11 Ltd (Developer), Beacons Business Interiors Ltd (Contractor), Watts Group Limited (Engineer), and Wells Senior (Project Manager).
Completed in September 2025, 5 Callaghan Square sets a new benchmark for adaptable, people-centred workplaces in Cardiff’s commercial landscape.
