Loft Conversion – Enfield, North London
This Enfield home has been transformed with a loft conversion, adding valuable extra space and enhancing the property’s functionality. The homeowners wanted to maximise their unused loft area, creating a modern, well-structured living space that integrates seamlessly with the existing home.
To ensure structural stability, safety, and full compliance with Building Control, PorthouseDean provided expert structural calculations, supporting the roof modifications, floor reinforcements, and load-bearing wall assessments to ensure a safe and efficient build.
Maximising Space & Light with Smart Structural Design
This loft conversion included:
✅ A fully reinforced loft floor – Supporting the weight of the new living space
✅ RSJ beam & steel support design – Strengthening structural openings
✅ Load-bearing wall modifications – Ensuring a seamless integration with the home
✅ Maximised natural light – Skylights and dormer windows for an open, airy feel
