Retrofit Expertise in a Complex Change‑of‑Use Development
Aran has successfully delivered a large‑scale cavity wall insulation package at Plantation Wharf, Battersea, supporting a complex commercial‑to‑residential conversion for Sulhill Limited.
Appointed to treat approximately 5,200m² of cavity wall area, Aran was responsible for navigating a range of technical, regulatory and site‑specific challenges, including change‑of‑use compliance, height waiver considerations, and strict thermal performance requirements - all within a constrained urban environment.
Aran’s ability to anticipate challenges and provide clear, confident guidance ensured the project progressed without delay. This approach enabled the client to move forward with certainty, knowing performance and compliance were fully achieved.
Project Overview
The project ran from November 2025 through to February 2026 and formed a critical part of a wider redevelopment programme at Plantation Wharf.
By taking a fully integrated approach, Aran ensured compliance and performance targets were met without disrupting the wider build schedule. The use of Knauf Supafil 40 enabled Aran to achieve required thermal standards while maintaining programme certainty on a technically constrained site.
Key Outcomes
- Approximately 5,200m² of cavity wall insulation delivered
- Full compliance with change‑of‑use and height waiver requirements
- Thermal performance targets achieved using Knauf Supafil 40
- Seamless integration with the wider construction programme
- Smooth, well‑managed installation across a dense urban site
Client Testimonial
“Aran Insulation provided an exceptional service during our commercial‑to‑domestic conversion at Plantation Wharf, utilising Knauf Supafil 40 to meet the project’s thermal specifications whilst covering approximately 5,200m² of cavity wall area.
The process was seamless from the start, with expert technical oversight that navigated the complexity of height waiver and material requirements. This high standard continued through to the installation phase, where the works were executed with precision and full regulatory compliance.
