St. Andrew’s House is located in the City of London, home to some of the World’s leading international financial and business operations. Neilcott was appointed to undertake a refurbishment and extension of St Andrew’s House including some structural alterations and a refurbishment of the existing façade including new glazing.

Construction works comprised:

Refurbishment to Category A standard of a single existing office building over 13 levels comprising one full basement, one part-basement, ground plus eight upper storeys plus one new office level and a rooftop open plant.

There is a retail area at basement level. New office entrance and rear cycle entrance to Thavies Inn. New glazing to the alleyway elevation.

The existing life safely sprinkler system will be replaced and serve all floors and the elevation drench system will be removed. All existing casement windows were replaced with a new single pane.

All curtain walling was retained, repainted, re-glazed and be provided with new external caps.

The new storey at roof level provides additional premium office space and is accessible via four new lifts and the existing fire escape stair and lift core at the rear of the building. New plant serving the building is located above the new roof level.

The existing lightwell adjacent to No.6 St Andrew Street was infilled with new slabs at all levels from ground to ninth floor. The existing lift circulation core previously included two lift shafts, which were removed and the corresponding voids infilled. As part of the alterations, four new lifts were installed through the existing building structure to serve all levels from ground floor to ninth floor. There is an additional existing fire-fighting lift to the rear of the building which was replaced by a larger lift. 

Alterations at first floor level include the repositioning of existing structural elements on the St Andrew Street elevation to enable re-modelling of the front elevation. The removal of these elements greatly improved the general appearance of the building and increased the natural light level inside the building at first floor
