Duke of York Project London roof extension

At Staggered, we specialise in structural steelwork, roof extensions, and bespoke steel fabrication for some of the UK’s most prestigious projects. One standout example is our collaboration with McAlpine on the Duke of York Project in London, where we engineered and installed a striking new pitched roof extension to transform the building’s flat roof into a cultural gallery space.

Transforming a Flat Roof into a Pitched Roof Gallery

The project brief was ambitious: convert an existing flat roof into a pitched roof capable of housing a modern art gallery. This required not only technical expertise but also precision in design and fabrication to ensure the new roof seamlessly integrated with the existing building structure.

Our Role in the Duke of York Roof Extension

We were commissioned to manufacture and install the structural steel framework that would form the backbone of the new pitched roof. Each element was fabricated in-house at our steel manufacturing facility to the highest tolerances before being delivered and assembled on-site in central London.

The new steel roof trusses provided both the architectural form and the structural strength needed to support the gallery extension. Working under full scaffold containment, our skilled installation team carried out the erection with meticulous planning and attention to safety.

Engineering Challenges & Solutions

Delivering a roof extension in London always comes with logistical and engineering challenges, especially within a busy urban environment. We coordinated closely with McAlpine and other contractors to manage crane lifts, restricted access, and site safety. The result was a smooth installation process, completed on schedule and to specification.

The Result: A Gallery-Ready Roof Space

The transformation of the Duke of York building showcases how structural steel solutions can unlock new possibilities for existing properties. By turning a flat roof into a dynamic pitched roof, the project not only enhanced the building’s aesthetic character but also created valuable new gallery space for cultural use.
