Paddington Over Station Development is a landmark 18 storey office building located above Paddington Station in London, occupying one of the city's most technically complex development sites. Built over an active railway infrastructure, the project creates a new commercial destination while seamlessly integrating transport, public spaces and workplace environments.

Designed by Grimshaw Architects, the 243,900 sq ft development provides highly flexible Grade A office space with external terraces on every floor.

Its distinctive triangular form responds to the alignment of the railway lines and the Grand Union Canal, while the fully glazed façades are complemented by sculptural vertical cores and an expressive transfer structure that reflects the engineering challenges of the site.

The scheme also delivers a new integrated entrance serving both Paddington Station and the London Underground, together with improved pedestrian connections and enhanced public spaces along the canal, contributing to the wider regeneration of Paddington Basin. Targeting BREEAM Outstanding, WELL Core Platinum and a 5.5-star NABERS rating, the development sets a new benchmark for sustainable, high performance commercial buildings in London.
