Ambika House was constructed in the 1960s, with the penthouse block later added in the 1980s. The original structure comprised of in-situ reinforced concrete columns, beams, and slabs - both solid and hollow pot.
The Project value was £5.4 million.
The scope of works involved the demolition of the original penthouse construction and, to the west, in the area to become the pavilion, demolition down to fifth floor level.
The new works included the erection of a braced structural steel frame supported by the original concrete columns, and lift walls incorporating resilient bearings to reduce the transmission of structural borne sound to neighbouring apartments. Certain areas within the penthouse required new column loads to be transmitted to the eighth floor by means of stiff spreader beams.
Further significant works were required to extend the lift shafts and to accommodate a swimming pool at 6th floor level within the pavilion.
