This commission involved the provision of full architectural and planning services for a 269,000 sq ft (25,000 sq m) development which involved total reconstruction behind retained facades.

The design was based upon the replacement of three internal lightwells with a single linear atrium. Floor widths and spacings were entirely re-configured to provide the maximum clear uninterrupted floor space, enabling a combination of cellular and open plan space. Lifts were placed within the atrium to facilitate ease of access to all parts of the building.

Particular emphasis was placed on achieving the high quality working environment needed by Amerada Hess to satisfy the needs of its young, highly skilled engineering and business development staff.

The project stages included: pre-construction period from first briefing to site start - six months; demolition period, while retaining facade - three months; construction period - 16 months.
