Cat B Fitout
We take your Cat A space and transform it into a workplace that reflects your organisation, your culture and the people who will use it every day.
A Cat A space provides the foundation. A Cat B fitout is where it becomes yours. We manage the full process of transforming a developer-finished space into a fully functioning, distinctly personalised workplace, from spatial planning and interior design through to mechanical and electrical fit out, furniture specification and technology integration.
The most effective Cat B fitouts begin with a genuine understanding of the organisation moving in. Before a layout is drawn or a finish selected, we invest time in understanding your culture, your people and your ways of working, ensuring the space is designed for how your organisation truly operates rather than how a generic occupier might.
Our progressive budgeting approach runs alongside the design process from the earliest stages, continuously validating cost so there are no surprises at contract stage. Full contractor governance, programme control and statutory compliance are managed throughout, ensuring your Cat B fitout is delivered on time, within budget and to the standard your organisation deserves.
A Cat B fitout is an opportunity to get it right.
Moving into a new Cat A space presents a genuine opportunity to create a workplace that truly reflects your organisation. The shell is clean, the possibilities are open and the decisions made at this stage will shape how your people work for years to come. Organisations that approach their Cat B fitout with a clear brief, engaged stakeholders and a structured delivery plan consistently achieve better outcomes than those that begin with a layout and work backwards. At Spectrum, we help organisations make the most of that opportunity, bringing the same rigour and people-first thinking to every Cat B fitout that we bring to every other stage of workplace transformation.
Workplaces built around people.
Every project we deliver starts with understanding your organisation, your culture, your people. The spaces we create are well-designed, well-used and still working well years after handover.
“Partnering with Spectrum Workplace was a game-changer for us. Being based in New York, delivering projects abroad can be challenging, but the Spectrum team made the process seamless. Their designers guided us through every aspect of the design, and their project manager provided consistent weekly updates, and even delivered the project a week ahead of schedule!”

Frequently Asked Questions
What is a Cat B fitout?
A Cat B fitout is the process of transforming a Cat A shell into a fully functioning, occupier-specific workplace. It covers design, partitioning, furniture, technology and all the elements that make a space distinctly yours.
What is the difference between Cat A and Cat B fitout?

How long does a Cat B fitout take?
Timescales vary by scale and complexity. Spectrum offers a clear, structured programme with full visibility at every stage and cost validated continuously throughout.
How do you ensure the fitout reflects our brand and culture?
Through our strategy and brief building process, we develop a deep understanding of your organisation before any design decision is made, ensuring the finished space feels distinctly yours.
Do you manage the full Cat B fitout process?
Yes, Spectrum manages the full Cat B fitout process. From initial strategy and brief building through to interior design, technical coordination, construction delivery and workplace onboarding, all under one roof.
