Upgrading the six-storey building will create 54,000 sq ft of office space and two new floors with the site renamed Oriel St Bride’s.

Work for client Original Works will retain 90% of the existing structure and employ low carbon construction techniques.

The scheme has already been recognised for its environmental ambition, having been selected for the UK Net Zero Carbon Buildings Standard Pilot Testing Programme.

Construction completion is scheduled for Autumn 2027.

Thomas Vandecasteele, Managing Director of Legendre UK, said: “This appointment reflects Legendre UK’s recognised strength in delivering technically demanding cut-and-carve projects in some of London’s most sensitive and constrained locations.

“This project combines our expertise in complex refurbishments and industry-leading sustainability credentials with our self-delivery MEP strategy. We look forward to working with the wider team to bring forward a scheme that sets a high standard for sustainable office delivery in the City, while also making a meaningful contribution to the surrounding community.”
