Delivering a high-quality CAT B office fit out requires more than just good design. It demands strong project leadership, clear client engagement, and robust contract administration to ensure the finished space performs as intended.
At One Trinity Gardens, Newcastle, Adept Building Consultancy successfully supported the delivery of a bespoke office fit out, tailored entirely to meet client requirements and workplace strategy.

From CAT A Shell to Bespoke Workplace
Following the CAT A provision, the 4th floor at One Trinity Gardens required full CAT B fit out works to transform them into a functional and high-performing workplace.
The scope included:
- New office fit out and full internal reconfiguration
- Meeting rooms and soundproof pods
- Kitchen facilities and breakout spaces
- Feature lighting and bespoke interior finishes
- Glazed partitions with acoustic performance
- Furniture integration and workplace technology
Rather than adopting a standard contractor-led layout, the scheme was developed around a bespoke design process, ensuring the final office reflected the client’s operational needs, branding, and long-term strategy.
Tailored Design to Client Requirements
A key part of the project was delivering a workplace that aligned with the client’s goals around:
- Hybrid working
- Staff wellbeing and retention
- Collaboration and productivity
- A professional and welcoming client environment
The design was carefully tailored to:
- Position meeting and client areas at the front of the suite
- Maximise natural light and views for core working areas
- Integrate breakout spaces to support collaboration
- Maintain a balance between brand identity and timeless design
This client-led, bespoke approach ensures the office is not only visually impressive, but commercially effective.
Employers Agent and Contract Administration
Adept Building Consultancy acted as Employers Agent, providing full oversight of the procurement and delivery stages.
Our role included:
- Preparing the client brief and tender documentation
- Managing the competitive tender process
- Carrying out detailed tender analysis
- Advising on contractor appointment and contract terms
- Administering the building contract through delivery
- Monitoring works on site for quality and compliance
This independent position is critical on CAT B office fit out projects, ensuring:
- Cost certainty and fair pricing
- Programme control
- Quality assurance
- Clear communication between all stakeholders

Managing the Fit Out Delivery
The project included mechanical and electrical alterations, coordinated alongside the architectural layout to minimise unnecessary disruption and cost.
A coordinated programme allowed for:
- Efficient design development with the contractor
- Early identification of risks
- Structured site audits and monitoring
- A clear pathway to practical completion
This proactive approach ensured that the works progressed efficiently while maintaining a high standard of finish.
Snagging and Quality Assurance
As with any CAT B office fit out, the final stage focused heavily on snagging and quality control.
Adept ensured:
- Detailed snagging inspections prior to completion
- Close-out of defects before occupation
- Coordination of certification and handover documentation
- A smooth transition for client move-in
This stage is critical in protecting the client’s investment and ensuring the space operates as intended from day one.

Delivering a High-Performance Workspace
The finished office space at One Trinity Gardens demonstrates how a well-managed CAT B fit out can deliver:
- A modern, professional working environment
- A strong “pull factor” for staff return to the office
- Enhanced collaboration and efficiency
- A high-quality client-facing space
By combining bespoke design with structured project delivery, the result is a workplace that supports both immediate operational needs and long-term business growth.
