Iconic steel window and door maker Crittall Windows has named a striking Sheffield renovation as the winner of its 2025 House of the Year Award.

Completed in partnership with Barnsley-based KJA Services, the project was inspired by a stay at London’s Soho Hotel, where homeowners Katie and Andy first encountered Crittall’s distinctive steel-framed glazing. That moment sparked a full-house transformation which impressed the judges for its clarity of design, cohesive use of steel and confident architectural language.

Set in an elevated position with views across the countryside, the contemporary property has been reimagined through the addition of Crittall glazing. What began as a modest upgrade quickly grew into a comprehensive scheme once the impact of the initial installation became clear.

“We were just blown away by the Crittall glazing,” said homeowner Katie. “It gave our space presence and personality. Once we saw how it changed the light and flow of the house, we knew we wanted it everywhere.”

The final design includes steel-framed windows, doors and an internal shower screen, all finished in RAL 7021 Black Grey. The installation brings rhythm and light into the heart of the home, while complementing its clean, modern lines.

Russell Ager, Managing Director at Crittall Windows, said: “This exceptional project demonstrates the perfect blend of architectural vision and Crittall’s renowned craftsmanship. It shows how our steel systems can elevate a residential space, creating a design narrative that feels both distinctive and timeless.”

Danny Murphy, Managing Director of KJA Services, added: “We’re honoured to win Crittall House of the Year for a second time. To deliver a project of this calibre so close to home makes it even more rewarding.”

The runners-up included a sensitive restoration of a listed property in Sussex by Lightfoot Windows and a technically ambitious South West London scheme by Bespoke Glazing Design.

Both were praised for their quality, creativity and thoughtful use of steel.
