11 Pilgrim Street

The Carter was a major refurbishment project in London’s Blackfriars


Client brief

The scheme, a complete modernisation over lower ground, ground and 7 upper floors; incorporates a rooftop extension, core reconfiguration and new reception area to maximise space and improve accessibility.

New amenity spaces transform the previous roof plant areas into roof-top terraces and green spaces, with further enhancements including new cycle parking facilities and upgraded employee areas, and a radical transformation of the basement level to include new locker rooms and shower facilities.

Our scope

Vision Arch were engaged to carry out the design, supply and installation of the curtain walling and aluminium rainscreen cladding from ground floor to roof level, as well as a glass pavilion, multi-level curtain wall with feature fins, copings to accommodate abseil loadings, specialist signage and a revolving door and pass door within the large curtain wall entrance screening.

Key challenges

Challenge 1

Feature fin integration with the Schuco SG Curtain Wall System and differential movements within the panelling

Challenge 2

Low Pitch, large glass roof to the Pavilion that could achieve Class 1 Walk-On

Challenge 3

Tight dimensional setting out requirements due to planning conditions relating to the proximity of St. Pauls Cathedral


The result

Designed with sustainability in mind, the new cladding elements provide excellent energy efficiency. The impressive entrance with large glass panes and signage creates an inviting reception for this refurbished building. However, it is the glazed roof extension and glass pavilion that truly stands out on this project, as allows for the most remarkable views of the city.
