Owners Land Securities obtained planning permission during 2010 for a comprehensive refurbishment. The redevelopment, designed by Aukett Fitzroy Robinson included replacing all glazing and shop fronts to improve energy efficiency and maximise the internal natural lighting. A new roof was added, and the canopy removed, allowing the original award winning architecture to come back to life. Internally the building was completely stripped out, the service core and reception areas reconfigured and all plant and machinery replaced.
Originally built in the 1970s, the fenestration of 123 Victoria Street is a striking architectural feature, with all elevations dominated by distinctive eight pane glazed bays. As part of the £42 million refurbishment programme, planning restrictions required the retention of existing aluminium frames but the important landmark complex also needed to deliver an improved thermal and acoustic performance.
The retrofit programme by Glassolutions provides an excellent model of delivering sustainability whilst respecting the aesthetics of the original building design and materials. Working with one of the UK’s leading fit-out companies, Como Group, and contractor Mace Construction, Glassolutions was brought in at an early stage in the design process.
This enabled the team to create a complete mock-up of an existing glazed eight panel bay, but fitted with new high performance double glazed sealed units housed within bespoke insulated frame extrusions in a structure which also featured specially designed gaskets to achieve water tightness. The design totally replicated the original style of the units but delivers improved thermal and acoustic insulation.
