St Pancras Basin

The frames were refurbished by a specialist iron-work company in Yorkshire before they were re-assembled, and each surrounds a circular apartment block, with a roof garden.

It was moved from a site some 660 yards (600 m) further to the south in late 2001, to prevent it being demolished by the construction of the Channel Tunnel rail link.

A reinforced concrete ring beam was cast at each of the joints, and the upper two sections, containing the water tank and the first floor with its feature arches, were removed by crane for transport to the new site.

The bottom section, which consisted of a plain plinth, could not be moved, as it was already badly damaged, and formed part of the adjoining viaduct wall.

To comply with the Channel Tunnel rail link construction schedule, work could not begin before 2 July 2001, and the original site had to be vacated by 31 December 2001.

Moving of the 140-tonne sections took place over three days in November 2001, and the building, which is known as St Pancras Waterpoint, will initially be used as a viewing tower.
