Located in the St James Conservation Area in the City of Westminster, 62 and 63 Pall Mall was a challenging project involving two listed buildings on a very tight and sensitive urban site. Both buildings were deconstructed to basement level whilst also retaining the façade at No.62 to preserve the historical interest and listed building status of the property. The two sites were redeveloped to provide a total of 9000 sqft of lettable office space over seven floors whilst below ground level, a new and refurbished basement and sub-basement levels provided hospitality and wine school facilities.
GSS Piling and Geostructural Solutions were appointed by Galliford Try for the substructure as well as for the superstructure.
Piling works involved the installation of a combination of contiguous bored piles, bearing piles and bored temporary cased piles around the existing basement, and as well as secant piles to the sub- basement. The site was further advanced into the pavement of Pall Mall, where numerous services were identified and where bored temporary cased piles were required for the substation and plant area which was built to service the site.
