Listed Building Lifted Back to its Original Location
THE daring move of a 300-year old listed smithy (a blacksmith's workshop) in the new St Giles Circus development in Central London, has been captured in this impressive footage.
The centrally located site is adjacent to Crossrail's future Tottenham Court Road station, and is to include a new, 800-seat theatre and commercial space.

Built in the 18th century, the smithy stands directly above a new Crossrail tunnel and on ground that required piling to support the new structures being constructed.
Proposals for the new development intended that the smithy be retained in its original position.

A number of options were considered - including specialist piling rigs, and a system of tunnels and transfer slabs dug beneath the existing smithy structure - though neither of these options proved viable.
The most effective proposal was to move the smithy to a temporary location about 82 feet (25 metres) away, while the site preparation works were carried out.

To move the building, an in-situ concrete slab was cast beneath its footprint, whilst the superstructure was braced with temporary steel work and supports.
A 750 tonne mobile crane then gently maneuvered the structure into its temporary location, enabling the necessary piling and foundation works to be carried out, before the operation was reversed to put the smithy back in place.

Restoration of the smithy is now due to begin, with the wider development scheduled for completion in 2020.
