A highly optimised structural design approach was adopted using full 3D finite element analysis modelling to holistically assess structural loads and minimise steel tonnage. The lightweight superstructure, combined with Glass Reinforced Plastic (GRP) floor panels weighing approximately 35kg/m² compared with 300–400kg/m² for a concrete equivalent, achieved up to a 90% floor dead load reduction. This enabled substantial reductions in structural steelwork, foundation sizes and concrete consumption, whilst eliminating the need for piling. The use of relatively small mass concrete pad foundations significantly reduced spoil generation, plant usage, noise and vibration during construction.

Drainage design incorporated sustainable urban drainage principles, with surface water management carefully coordinated to avoid impacts on existing railway drainage infrastructure. Careful assessment of ground conditions and existing buried assets further informed foundation positioning, reducing the extent of intrusive groundworks required

Additional environmental measures included rainwater harvesting, intelligent energy-efficient lighting controls, solar PV panels, retention of existing mature vegetation and biodiversity enhancement through landscaping and integration of a living green wall system.
