We’re very pleased with the end result at 180 Great Portland Street. The building refurbishment won a BCO Innovations Award for its innovative solutions and it’s fair to say that the floor based air conditioning system played an essential part.

Stunning refurbishment of former Edwardian residential mansion block in the heart of London’s West End, the building was transformed from cellular offices into five stories of high class, open plan accommodation.
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 underfloor approach, this ensured that the offices could 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.
