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 said to be inspired by a stay at London’s Soho Hotel, where homeowners Katie and Andy first encountered Crittall’s distinctive steel-framed glazing.

Set in an elevated position with views across the countryside, the finished build reportedly impressed the judges for its clarity of design, cohesive use of steel and confident architectural language.

“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.

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.
