Across this multi-site project area, our client required a series of reliable and compliant rooftop entry system to safely house critical equipment. Every location was different - varying roof layouts, equipment footprints, and operational needs - which made TopBox the ideal solution.

TopBox is our fully customisable GRP roof entry system, developed to give facilities teams the flexibility, safety, and durability they need… without disruption to ongoing operations.

The Challenge

Our client needed:

✅ Multiple roof access points across the facility

✅ Each unit tailored to specific spatial constraints

✅ Protection for electrical and mechanical equipment

✅ Long-term durability in exposed rooftop conditions

✅ Fast, efficient installation with minimal downtime

Traditional on-site construction wasn’t viable due to time restrictions and space limitations. A pre-engineered GRP system was the smarter, safer option.

Our Solution: Bespoke TopBox Configurations

We designed, manufactured, and delivered several completely bespoke TopBox units - each one created to suit the exact requirements of its rooftop location.

Key design features included:

Custom sizing and footprint optimisation
GRP construction for strong weather resistance
Secure and compliant access routes
Internal layouts designed around equipment
Delivered prefabricated for smooth installation

Because installation could be carried out quickly and cleanly, disruption to operations on site was kept to an absolute minimum - a key requirement for the client.

Benefits Delivered

TopBox provided immediate value by ensuring:

✅ Safer working access for maintenance teams

✅ Secure housing for sensitive rooftop equipment

✅ High durability with low maintenance requirements

✅ Fully compliant installation approach

✅ A future-proof solution for expansion or upgrades

The client now has confidence knowing each roof access location is protected and operational - regardless of environmental conditions.

Built for Every Roof, Designed for Your Needs

This project is a strong example of how flexible and adaptable TopBox can be. Whether it’s one unit or a large multi-site rollout - we shape each TopBox to fit the project, not the other way around.
