Following an international design competition, the square has been transformed into an open and welcoming public space, creating new connections across the square and with the surrounding city. The redevelopment of its south-eastern side, and Two St Peter’s Square in particular, has introduced renewed commercial activity and contemporary architecture of a quality and scale to complement the grandeur and character of the historic buildings, strengthening the entity of the square and its presence within the city.

With every aspect of its design we sought to lock Two St Peter's Square in place, embedding it in its surroundings. Form and massing, materiality and articulation were all carefully considered and refined to reflect the quality and character of the building's historic setting within a contemporary and high-performing BREEAM Excellent and EPC A-rated design.

Open and flexible floorplates offer tenants maximum net useable space and benefit from excellent natural daylighting, solar shading and views out to the magnificent buildings nearby. The eye-catching tracery screen cantilevered above its main entrance has become a popular landmark and a marker for the square while the floor-to-ceiling tracery panels bring the character of the building and its historic context into the office floors.

"The move to Two St Peter's Square was an important one for us all at EY. It's a fabulous new building in a superb location. However it's much more than just having a new physical space in which to work – it's about enabling a different way of working."

"SimpsonHaugh overcame technical and design challenges to produce a unique façade of timeless elegance appropriate to the building’s historic and civic location among listed buildings. The decorative façades are superb and we wouldn’t be surprised if Two St Peter’s Square inspires techniques and approaches for future developments."
