Commercial Unit Conversion
We provided structural designs for the development of two new commercial units formed by modifying a disused commercial unit.
Project Overview
This project involved the development of two new commercial units by modifying a disused commercial property in Sunderland.
The existing building was a steel portal frame, and the proposals required the removal of the end two portal frames on the south-west facing elevation to allow for the introduction of a drive-thru function.
Rather than discarding the removed steelwork, it was reused for bracing and gable posts. By repurposing the existing steel structure, the development achieved a much lower embodied carbon footprint compared to constructing a new frame from scratch.
This sustainable approach not only supported environmental goals but also prevented the structure from deteriorating further, which could have negatively impacted the surrounding area.

Project Challenges
The main challenge was ensuring structural stability during the removal of the end portal frames while keeping the building safe and functional throughout the works.
In addition, the new design had to provide long-term structural performance suitable for its permanent use as a drive-thru facility.
The Solution
We developed a structural design strategy that allowed for the safe removal of the end portal frames without compromising stability.
The steelwork that was taken out was carefully repurposed as bracing and gable posts, maximising efficiency and reducing material waste.
By reusing the existing steel frame, the design preserved the embodied carbon within the original structure while achieving the new layout requirements.
This approach balanced sustainability with safety and performance, ensuring the building could serve its new commercial purpose.
The Outcome
The project successfully transformed a disused commercial building into two vibrant new units, including a Starbucks drive-thru.
The reuse of the steel frame minimised the carbon footprint and extended the life of the existing structure, while the structural alterations ensured a safe and durable long-term solution.
