About the event

Project Description & Keltbray’s Work

Paddington OSD site is situated parallel to the Paddington Basin and sits adjacent to Paddington Station. The current Northern Station Entrance/exit to Paddington sits within the site boundary and will eventually be enveloped once the final scheme is completed. The project comprises a new 21-storey scheme providing approximately 22,155 sqm (15 office floors) of commercial office accommodation and 2 storeys of basement ancillary space. Ground floor to level 4 provides an enhanced reception area along with EOT and shower facilities for tenants. All office floors will have access to private balconies overlooking the canal.

The scheme consists of:

• Maintaining access and use of the existing taxi rank.
• New entrance box for the LUL entrance.
• 15 floors of commercial office space with adjoining balconies.
• End-of-trip facilities including changing areas and bike storage
• Refurbishment of existing service road at basement level
• External refurbishment of canal towpath including new public lift and stairs to Bishop’s Bridge.
• Mace will continue with the completion of the Superstructure, consisting of steel frame and composite RC Slabs. The building will be handed over fully fitted out to a CAT A Specification.

Keltbray have been appointed by Places for London and Helical to act as Principal Contractor to undertake the following works associated with the Paddington OSD Project:

• Station Entrance modifications.
• Piling & foundations to station interface areas.
• Secant wall propping and earth-berm removal.
• Construction of East and West Cores (including slipform, reinforcement and cast-in items).
• Formation of B2 basement slab, foundations, and pile caps (east, west & north).
• Modifications and reinstatement of existing secant walls and capping beams.
• Installation of tower-crane base (TC1) and associated substructure works.
• Construction of substation box structure and fit-out interfaces.
• Integration of ground-source heat-pump (GSHP) facilitating works and manifold pipework.
• Coordination of drainage and civils to and within B2 level.
• De-construction of the existing taxi ramp structure and removal of parapets and associated elements.

Keltbray started works on site in June 2025 and are currently working on the main scope items due to be completed in February 2027. This will be followed on by the planned return works including the demolition of the existing taxi ramp structure in the summer of 2028. The appointed main contractor will then continue with the scheme to project completion.
