New Build Development – Whitefield, Greater Manchester
This stunning new build in Whitefield showcases modern architectural design with a striking floating roof effect, achieved through precise structural engineering and innovative steelwork solutions. The homeowners wanted a contemporary, spacious, and structurally unique home, with the standout feature being a 3m cantilevered flat roof, creating a visually impressive overhanging structure.
To turn this ambitious design into reality, PorthouseDean provided expert structural calculations, ensuring that the roof, support system, and overall structure were designed for stability, durability, and compliance with Building Control regulations.
Engineering the Floating Roof Effect
Key design elements included:
✅ A 3m cantilevered flat roof – Creating a bold, modern architectural statement
✅ Spliced steel beam section – Supporting the overhanging structure with precision
✅ Galvanized steel CHS post – Providing strength while maintaining a sleek, minimalist aesthetic
✅ Strong yet lightweight materials – Ensuring long-term stability without overloading the structure
What we did
Our contributions to the project included:
✔ Structural calculations for the new build – Ensuring stability and compliance
✔ Cantilever beam analysis – Designing a safe and effective overhanging roof system
✔ Steel beam & RSJ integration – Supporting large spans for open-plan and contemporary aesthetics
✔ Foundation design – Reinforcing the base for the cantilevered section
With expert engineering in place, this Whitefield new build now features a stunning, high-end design, blending architectural innovation with structural excellence.
