45 Cannon Street

Delivering modern office and retail space in one of the most vibrant and dynamic areas of London

45 Cannon Street is a new-build office and retail development located in the heart of the City of London. The scheme, which was completed at the end of 2016, includes 84,600 sq ft of modern British Council for Offices Cat-A standard offices set over basement, ground and 7 upper floors. In addition, the building includes retail space fronting Cannon Street and Bow Lane.

Designed by acclaimed architects Fletcher Priest, not only is the project a landmark in the area but it is also constructed to BREEAM® ‘Excellent’. Gleeds provided cost management, health and safety services, as well as acting as employer’s representative for Morgan Capital Partners.

Respecting restrictions and achieving aspirations

The development is located a stone’s throw from St. Paul’s Cathedral. Its close proximity placed it under stringent development restrictions that protect sightlines to London’s most iconic and important cathedral. The team worked closely with the City of London planning authority to develop a design that protected the viewing corridor without compromising the client’s floor space aspirations.

At an early stage of the project, the upper storeys of the building were cleverly designed to protect St. Paul’s viewing corridor whilst maximising the use of space. As a result, the building incorporates a stepped roof on the uppermost floors. Expansive terraces provide up to 14,517 sq ft of virtually column free space with excellent natural light on all sides and spectacular views of St. Paul’s.

Communication to success

The development is constructed over a live underground pedestrian tunnel serving Mansion House station. The tunnel has been subject to archaeological investigation during the substructure works phase. The tube entrance had to be closed for several weeks at a time to allow for the entrance structure to be demolished and rebuilt to incorporate a disability access lift.

The works had to be carefully planned and were successfully delivered thanks to regular communications with third-party authorities including City of London Corporation, Transport for London, and various statutory utility companies.
