Loft Conversion – Whitefield, Greater Manchester
This Whitefield home has been transformed with a dormer loft conversion, adding valuable extra space and increasing the property’s functionality and value. The homeowners wanted to make the most of their unused loft space, creating an additional bedroom and en-suite while ensuring the new structure was safe, efficient, and compliant with Building Control.
To bring this project to life, PorthouseDean provided expert structural calculations, ensuring the roof structure, floor loadings, and new dormer extension were fully supported. The project was delivered in partnership with JPL Design & Construct Building Services.
Maximising Space & Stability with Smart Structural Design
This loft conversion included:
✅ A dormer extension – Providing additional headroom and usable space
✅ A reinforced loft floor – Ensuring it could support the new living area
✅ Steel beam (RSJ) design – Strengthening structural openings and supporting the roof modifications
✅ Load-bearing wall assessments – Ensuring safe structural modifications
What we did
Our structural role included:
✔ Structural calculations for the dormer loft conversion – Ensuring compliance with Building Control
✔ RSJ & steel beam design – Supporting new load-bearing structures
✔ Roof and floor reinforcement – Strengthening the loft to safely accommodate living space
✔ Load distribution analysis – Ensuring weight was properly transferred through existing walls and foundations
Thanks to precise engineering and planning, the homeowners now enjoy a spacious, modern loft conversion, providing extra living space without needing a full extension.

Why Extend Your Home?
More Space, More Possibilities
Create an open-plan kitchen, a family hub, or a bright entertaining space.
A Date You Can Plan Around
You choose the delivery date, and the price follows the date.
More Natural Light
A wider opening to the garden needs a beam sized for the load above it. The calculations set that size.
Personalised Design
Every house is built differently. The calculations work from your drawings and the structure you already have.
