CAT B Fit outs

Bringing your workspace to life

Cat B fit outs that go beyond aesthetics. Ensuring your office feels as good as it looks.

A Cat B fit out is the stage where an office space is tailored to the needs of the occupier. It builds on the infrastructure provided in a Cat A space and adds the layout, finishes, furniture and technology needed for a fully operational workplace. 

At Design Tonic, we combine strategy, design and delivery to create workplaces that support both your business goals and your team experience.

Our Cat B fit out approach

Workplace strategy

We start by understanding how your team works. Through discovery workshops and research, we identify the right balance of collaboration spaces, focused areas and social environments.

Design that reflects your brand

Your workspace should tell your story. From colour palettes to materials and graphics, we design interiors that bring your brand identity into the physical environment.

Seamless delivery

Our team manages the process from concept through to completion, ensuring your project runs smoothly and is delivered on time.

Intelligent layouts

Smart spatial planning ensures your office supports productivity, movement and collaboration. Every square metre is designed with purpose.

Execution

A Cat B fit out is where a workspace truly comes to life. It takes the blank canvas of a Cat A space and transforms it into a fully functional, branded environment designed around how your team works. Whether you're moving into a new building or reimagining an existing space, we help you turn potential into a workspace your team will love.

How we deliver a Cat B fit out

Discovery

We begin with an in-depth consultation to understand your target tenants and the unique features of your space. 

Design & Development

We develop a tailored Cat B plan to refresh the interiors, focusing on elements that will maximise space and features. We refine the design based on your feedback and provide clear cost estimates and timelines for approval.

Delivery

Once the design is approved, we ensure that all work is completed to the highest standards. Our team coordinates trades and installations, maintaining clear communication throughout.
