The building is designed by architects Webb Gray, who have featured in the three storey curtain walled building, two wings with a central core which includes natural stone, low carbon technology building services, and a natural light environment.

Situated at Tachbrook Park the consultants specified six off Air Handlers Northern air2O rooftop central.
Station packaged air handling systems.
The packaged air handling units incorporate:

  1. Air2O two staged evaporative cooling units model CRS – 12.500 hybrid, complete with intake filters and UV filters, DX coil and compressors.

This project comprised six off CRS 15.000 air2O units which incorporated a first stage direct evaporative cooling section, a second stage in direct evaporative cooling section, with a final DX 35Kw stage cooling system all inbuilt within the air2O unit.
