Permasteelisa Group Appoints New Group CEO
Permasteelisa Group, the leading international façade specialist, has appointed Seb Fossey as its new Group CEO to lead the organisation into its next phase of development and growth.
Seb, whose most recent role was as Managing Director of specialist engineering contractor, McGee, has over 26 years’ experience working as a senior construction and engineering leader. He has extensive experience of delivering technically complex major projects both in the UK and internationally.
Before joining McGee in 2017, he spent more than 15 years at Laing O’Rourke, progressing from major-project delivery roles to becoming Technical Leader for its UK construction business. He joined McGee as Operations Director and was appointed Group Managing Director in 2019, taking responsibility for the company’s strategy, operations and client delivery.
During his leadership of McGee, Seb oversaw the company’s transformation from a demolition and groundwork subcontractor into a specialist engineering contractor offering integrated demolition, piling, civil engineering and structural services.
His experience combines technical and operational leadership, business transformation and the safe and successful delivery of complex projects. He has a strong focus on strategic leadership, building collaborative client relationships, delivery certainty and the construction industry’s response to the carbon agenda.
Peter Bacon, Permasteelisa Group’s Executive Chairman, comments:
“We are delighted to have appointed Seb as our new Group CEO. He will lead our team of regional CEOs in Europe, the US, Asia Pacific and the Middle East as they continue to drive real success across their operating regions."
“Seb is a proven leader in our industry, and will bring strategic, commercial and technical skills to his new role. His leadership, management and operational experience, coupled with a strong commitment to customer service excellence, will help further our ambitions for the business.”
Seb Fossey comments:
“Permasteelisa Group has an international footprint with strong capabilities and an outstanding reputation for delivering some of the most iconic building and retail façades all over the world."
“I am looking forward to joining such a talented team with a continued focus on operational excellence, innovation and meeting customers’ carbon commitment goals.”
Seb officially joins the Group on 28 September 2026, at which point Peter Bacon will relinquish his executive responsibilities, while remaining Chairman of the Group. Liam Cummins will transition from his current role as Deputy Chairman to a Non-Executive Advisory Director of the Group.
Peter Bacon added:
“I would like to take this opportunity to thank Liam Cummins for his contribution as Group CEO and more recently Deputy Chairman. Liam injected real focus, energy and pace into the Group’s transformation programme and we thank him for his valuable leadership contribution."
"We look forward to continuing to benefit from Liam’s input and advice as a Non-Executive Advisory Director."
Over the last year Permasteelisa Group has won a number of prestigious contracts including 60 Gracechurch Street and 60 Queen Victoria Street in London, San Francisco International Airport, the Chinese Medical University in Taiwan, and a contract to deliver the façade for the KYKLOS Centre for Arts and Cultures in Piraeus, Greece.
In the same period the Group has completed a number of high-profile schemes adding to its impressive portfolio of over 3,000 projects worldwide – including the cross on top of Barcelona’s Sagrada Familia, Louis Vuitton’s ‘The Louis’ in Shanghai, a project for YouTube and at 3050 Aventure in the US, and several projects in its core London market, including 2 Aldermanbury Square, 334 Oxford Street and One Liverpool Street.
