The development brief was to maximise lettable space, whilst minimising material and construction costs.  The project had particular challenges with restricted headroom, structural and facade limitations.  Sustainability played an important role in the brief, with the specification of the building services having to allow for future flexibility whilst offering potential energy savings.  By adopting the Under Floor approach, this ensured that the offices were able to provide optimum comfort cooling and maximum versatility for speculative tenants

The flexible under floor HVAC solution allowed a minimum floor plenum of 200mm maximising the floor to ceiling height and post refurbishment, the work space enabled a 35% increase in total occupancy
