10 Piccadilly: engineering the next chapter of a West End landmark

Completing Regent Street’s iconic curve at Piccadilly Circus, 10 Piccadilly is being transformed into a mixed-use destination combining workspace, retail, hospitality and new amenity spaces. The development will also become home to Time Out’s first London market, occupying three floors of the building.

The project forms part of The Crown Estate’s two million sq ft West End development pipeline, supporting its wider strategy to renew key assets, strengthen the area’s commercial offer and steward important heritage buildings for the long term.

Elliott Wood is providing structural engineering, development infrastructure and specialist BIM services, helping the project team unlock greater value from the existing Grade II listed asset while managing technical and delivery risk.

Our structural strategy balances significant adaptation with targeted intervention and maximum reuse of the existing structure.

Detailed investigations have established the condition and capacity of a building shaped by decades of alteration. This evidence-led approach is allowing the design team to make substantial changes while avoiding unnecessary strengthening and retaining as much of the existing structure as practicable.

Engineering interventions include new service cores and risers to support contemporary occupier requirements, the infill of historic lightwells to increase usable and lettable floor area, and structural alterations to create new roof terraces and amenity spaces.

Together, these interventions are helping adapt the building for modern commercial use without losing the value already embedded in its historic fabric.

Appointed from RIBA Stage 2, Elliott Wood’s BIM services team established a structured information management and model coordination process across the design team.

Monthly multidisciplinary model reviews have helped identify and resolve coordination issues earlier, supporting the integration of modern building services within the constraints of the existing structure.

By combining detailed investigation, structural engineering and digital coordination, the team is providing greater certainty as 10 Piccadilly moves from design into construction.

The result is a strategy focused on making an important West End asset work harder: creating additional usable space, accommodating new uses and infrastructure, and maximising reuse while reducing unnecessary structural intervention.
