It was previously thought that construction until 2012 at the earliest thanks to the current tenancy agreement for the site.
The scheme only has a mere 10 passenger lifts thanks to the use of express double decker lifts between the ground floor and mid height lobbies.
The lower part of the tower splays out on one side giving it the appearance of twisting slightly.
One of the advantages of the tower flaring out on the southern side is that it reduces the wind currents that are experienced by pedestrians by absorbing them. This is further reinforced by the treatment to the lower facades.
The cladding is purposefully designed to reference the international style of St Helens to blend in more with that conservation area and create a coherent whole.
The top of the tower is designed to reach the shoulder of Tower 42.
At night it has been designed so that the cladding will seem transuculent rather than transparent with the crown always illuminated.
Originally the tower was set to be six floors taller but this was reduced following concerns it would detract from 30 St Marys Axe and the Heron Tower and lead to a flat skyline.
