Factory Extension – Portbury
Project Overview
This major industrial development focused on expanding gypsum production capabilities within the UK. Delivered in collaboration with McLaughlin & Harvey, the project represented a significant investment of £7.9 million and spanned a construction timeline from 2022 to 2024.
Project Scale & Design
The extension was a substantial undertaking, measuring approximately 40 metres in height and extending 520 metres in length. To meet all performance and compliance requirements, a team of four designers was tasked with developing comprehensive construction drawings. The design process was a collaborative effort involving:
- Architectural design
- Structural steelwork
- Mechanical & electrical coordination
Working to a structured BIM Execution Plan (BEP), the design team produced a total of 364 drawings to support accurate and efficient delivery of the project.
Construction & Materials
A range of high-performance materials and systems were installed to ensure the durability, safety, and efficiency of the extension:
- Roof and wall cladding systems provided a robust and weather-resistant external envelope.
- Insulated gutter systems contributed to effective water management.
- Rooflights enhanced natural lighting to support energy efficiency and internal working conditions.

Supply Chain
A broad and experienced supply chain was key to the successful delivery of this project. Key contributors included:
- King Lifting – Crane and lifting services
- Euroclad – External cladding systems
- AKV – Specialist support services
- Gravity Solutions Ltd – Installation works
