Case Study



Multinational mining and energy group Rio Tinto’s new £250m global headquarters would see them relocate from Paddington into a 97,000 sq. ft premises at 6 St James’s Square, London.


The design for the impressive space included an entire floor for luxury office meeting areas as well as a high-quality meeting suite for their European executive team.



Radii designed a completely tailor-made glazed partitioning system for Rio Tinto — named ‘Rio’ — to meet their high-end requirements.


Unlike other glazed partitioning with full-height glass panels, the Rio system uses multiple individual double-glazed windows for all partition fronts, fully extruded by Radii and acoustically rated at 45dB RW. Furthermore, the partitioning was installed using recessed deflection heads to create cleaner lines throughout.


For the glass doors two solutions were provided: Hogan pivoting doors and Glide sliding doors, both rated at 38dB RW. For all doors Radii also supplied aluminium handles, manufactured to a specific design as per the architect’s vision.


To finish, opaque Opal Frost manifestation were added to areas of the glazed partitioning for added privacy.

Dedication to precision and future innovation


The work at St James’s Square demonstrates that, while Radii holds a catalogue of well over 200 extrusions, we will look at each project presented to us as a unique opportunity to demonstrate our technical ability and design expertise and create a bespoke, unique solution.


This also gives a client the opportunity to not only specify technical requirements but aesthetic ones as well. For Rio Tinto, all the glazed partitioning elements for this project were manufactured utilising individually framed double glazed panels to create an on-trend, industrial style in all their meeting suites.


Moreover, the significant number of components in the bespoke Rio system meant that an organised approach to delivery was vital. Part of Radii’s on-site process involves sophisticated product tracking, allowing fit-out teams to rapidly identify the location for each item before being installed.
