David Crookes was appointed by a leisure and entertainment client for the refurbishment of a basement site at 16 West Central Street, London WC1. The proposals involved the conversion of the existing basement spaces formerly a Post Office stable for use as a nightclub. In addition a new restaurant with basement space was to be constructed in the adjoining car park.
Early desktop research showed that the proposed basement space was to be constructed in close proximity of the West Central Street Post Office and that the Post Office railway ran diagonally across the site at a depth of approximately 12 metres. Taking account of this, the design was progressed with a basement scheme consisting of deep strip footings which had a formation some 3.5 metres deep in the natural gravel. This involved shuttering the trenches and deep excavation but avoid the use of piling techniques which would have possibly fouled the tunnel.
