Steel Balcony & Terrace – Dore, Sheffield
This Sheffield home has been elevated—both literally and architecturally—with a sleek steel balcony and terrace, creating a striking modern extension that enhances both functionality and aesthetics. Designed for seamless outdoor access and a minimalist, industrial-chic finish, the new structure maximises elevated views while ensuring long-term structural integrity.
To bring this bold architectural design to life, PorthouseDean provided expert structural calculations and detailed drawings, ensuring the project was both visually striking and structurally sound.
Maximising Space with a Contemporary Design
This project featured:
✅ Beam and block flooring – Providing a solid terrace foundation
✅ Parallel Flange Channel (PFC) edge beams – Ensuring strength and structural efficiency
✅ Slender hollow section balcony frame – Creating a light, modern aesthetic
✅ Braced steel supports – Securely tying the balcony back to the main structure
What we did
Our role in this transformation included:
✔ Structural calculations for the balcony and terrace – Ensuring safety and durability
✔ Steel beam and bracing design – Maintaining a lightweight but structurally strong framework
✔ Load analysis and wind resistance checks – Securing the structure against external forces
✔ Building Control compliance – Ensuring full approval for a smooth build process
Thanks to careful engineering and high-quality materials, the new steel balcony and terrace offer a perfect blend of durability, elegance, and modern outdoor living.
