Calisen required a new office environment in Wigan to support a growing workforce and reflect the organisation’s focus on smarter energy solutions.

The brief was to create a modern workplace that balanced collaboration, focused work and staff wellbeing within an existing building shell.

The project involved a full office design and fit-out, transforming the space into a functional, people-focused working environment.

The layout was organised around a mix of open-plan work areas, enclosed meeting rooms and informal collaboration spaces.
Clear zoning allows teams to move easily between focused work, meetings and social areas throughout the day.

Design choices draw on the building’s industrial character, with exposed brickwork, visible services and a restrained material palette providing a robust backdrop for daily use.

Acoustic baffles and ceiling rafts are used throughout open areas to manage sound and improve comfort without enclosing the space.
Large meeting rooms feature suspended feature lighting and timber ceiling elements to visually define spaces and support longer periods of use.
Glazed partitions allow natural light to pass through the floorplate while maintaining privacy in meeting rooms and quiet spaces.
Breakout and lounge areas introduce softer furniture, planting and textured finishes, creating contrast with the more functional work zones.
Branding is integrated through signage, wall graphics and colour accents, reinforcing identity without dominating the workspace.

The key challenge was accommodating multiple work settings within a single open floorplan while maintaining clarity and ease of movement. This was addressed through straightforward circulation routes, consistent furniture layouts and clear visual cues between different zones.
Respecting the mill’s original architectural features while delivering effective acoustic performance, particularly within spaces with 4m-high ceilings and large original windows, required detailed acoustic analysis to control reverberation and reduce unnecessary noise without compromising the character of the building.

The completed office provides Calisen with a flexible, modern working environment that supports a range of work styles.
Teams benefit from improved acoustic comfort, better access to natural light, and a clearer distinction between collaborative and focused spaces.
The workplace supports day-to-day efficiency while offering spaces that contribute positively to staff experience and wellbeing.
