At DSP Interiors, we specialize in transforming spaces to boost productivity and enhance innovation. Recently, we had the opportunity to complete an exciting fit-out project for Promethean Particles, a leading chemical manufacturing company located in Nottingham. This project transformed a space, previously only used for storage, into a functional and efficient office space designed to meet the company’s evolving needs.


Promethean Particles Ltd, renowned for its innovative approach to chemical manufacturing, sought to upgrade its workspace to support its growing team and operations. The completed project reflects DSP Interiors’ commitment to creating efficient, stylish, and sustainable office spaces tailored to clients’ needs.
The project involved a comprehensive reconfiguration of the mezzanine area, starting with the installation of fire-rated partitions to define the office layout and ensure compliance with safety standards. To improve access and functionality, the existing staircase was removed and reconstructed, seamlessly integrating it into the new design.
From Vision to Reality
Our comprehensive fit-out project included:
- Space Planning & Design: Crafting an intelligent layout to maximize functionality.
- Partitioning for Structure and Safety: Fire-rated partitions and jumbo stud partitioning were installed to shape the mezzanine and staircase areas while adhering to strict safety standards.
- Structural Adjustments: Including the removal and reinstallation of the staircase for improved access.
- Mechanical and Electrical Work: A seamless integration of lighting, ventilation, air conditioning and connectivity services to support a productive environment.
- Ceiling & Acoustic Solutions: Insulated ceiling grids and quilt insulation were added for sound control and temperature regulation.
- Stylish Interiors: From ergonomic furniture to durable carpets, every detail was selected to create a cohesive, professional aesthetic.




Highlights of the Transformation:
- Safety and Accessibility: Careful planning ensured compliance with fire safety regulations.
- Optimized Space Usage: Utilising the mezzanine floor increased operational space significantly.
- A Polished Finish: Smooth surfaces and ergonomic furniture provided a refined, welcoming environment.
A big thank you to Promethean Particles for trusting us with this project. Their new workspace demonstrates how thoughtful design and skilled craftsmanship can completely transform a space.
