A new interim Chief Construction Adviser has been appointed by
the Ministry of Housing, Communities and Local Government today
(30 September 2025).
Thouria Istephan, an architect with extensive industry experience
and knowledge of building safety standards, has been appointed to
provide expert, independent advice to ministers and government on
building safety and regulatory reform.
Thouria 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.
The Minister for Building Safety 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.
Interim Chief Construction Adviser Thouria 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.
Before Thouria's work on the Grenfell Tower Inquiry panel, she
spent decades at leading international design and architectural
practices, where she held senior roles including Construction
Design Management Manager, partner and Technical Design Deputy
across major projects and sectors.
This 12-month, interim appointment will allow vital work to begin
now with expert leadership in place to guide and maintain
momentum on reform and regulatory design, while the government
establishes the role permanently next year.
Thouria was appointed through a direct ministerial process, in
line with Cabinet Office guidance and her role will be taken up
on a part-time basis.
