A 1980s out-of-date office building was transformed into a new workplace that includes a public atrium, commercial office space, café and restaurant space and rooftop terraces.

Key Challenges

  • High architectural specification and intent to achieve
  • Complicated access control interface
  • Co-ordination role across multiple trades and finishes

The Brief

Working with the existing structure, the concrete frame was extended both vertically and horizontally and the internal service courtyard enclosed into a 6-storey glazed atrium. Working alongside Bam Construction, Colorminium were commissioned to lead the detailed design process of glazing works internally. This included close communication with the concrete frame, internal walls, ceilings and finishes, M&E and flooring.

Our Approach

Whilst unitised structural glazing was used for the main atrium glazing, the lobbies off each lift core and flanking the atrium space all had an onerous fire-rating that could only be met with a steel glazing system. A lightweight steel framing system was used to create the apertures within the concrete frame and then clad in fire resistant boarding before a sacrificial top sheet was installed. The doorsets and glazing were then inserted to complete the installation.

Complicated access control facilities were required to each doorset that Colorminium also led and delivered.

The Result

The contemporary finish is stunning, functional and fitting to the environment and overall design. Shortlisted for the 2011 RIBA Stirling Prize and winning numerous other awards, the project will stand out for years to come.
