Istephan will “play a central role helping to shape the future of the built environment sector, ensuring that safety, delivery and accountability are central to decision-making, with residents’ voices at heart.”

Her appointment marks a key milestone fulfilling the government’s response to the Grenfell Tower Inquiry Phase 2 recommendations.

Istephan was a member of the Grenfell Tower Inquiry panel and has more than 25 years of experience at architect Foster and Partners.

The role of Chief Construction Adviser was created in 2009 but discontinued in 2015 before the Grenfell inquiry recommended its reintroduction.

The previous incumbents were quantity surveyor Paul Morrell and civil engineer Peter Hansford.

The Minister for Building Safety Samantha Dixon said: “Ms Istephan brings extensive experience and a strong commitment to public service that will bring valuable insight and meaningful change to building safety in this country.

“Her work will drive the transformation needed to restore trust and improve safety, accountability and confidence across the sector.”

Istephan said: “This role enables me to apply my extensive architectural experience, together with insights gained through my work on the Grenfell Tower Inquiry. It represents a unique opportunity to provide independent advice that promotes progressive and proportionate standards.

“I am committed to playing my part in addressing the devastating consequences of past failures – on people, on the environment, and on the innocent lives lost – as well as the enduring emotional and financial burdens that so many continue to face.”

The 12-month, interim appointment will allow work to begin now to guide and maintain momentum on reform and regulatory design, while the government establishes the role permanently next year.
