Various new onsite amenities shall be provisioned across 50,000m2 of floorspace, representing a five-fold increase. Amongst the various retailers and commercial operations planned are two restaurants that are to operate on the station's roof, along with a gym, tennis court, putting range, 1 km fitness trail along the façade, and in excess of 7,000m2 of green space. To improve accessibility throughout, a total of 55 lifts and 105 escalators shall be installed, more than doubling the pre-redevelopment number. Eco-friendly considerations have also been made, conforming with the demanding BREEAM standards and incorporating features such as 3,200m2 of solar panels. Despite the ambitious scope, great care shall be taken to preserving its historic architecture and appearance, the station having been regarded as a national heritage site in its own right. The project has reportedly been modelled using several other major stations, including Britain's St Pancras Station and America's Grand Central Terminal.
