The Frame is a three-story steel framed extension including roof and parapet, to the existing Pepper Pot South Building with metal decking to form composite concrete floors at each level, with a spiral staircase situated within this extension.
A circular spiralling staircase with vertical bar balustrade to gain access to the first-floor level within the redevelopment of the Pepper Pot South Building for Wavensmere Homes on their Nightingale Quarter development in central Derby.
The stairs main central column is supported at the base on a steel beam positioned on concrete padstones below ground floor level and then connecting into the roof structure at the top of the new rear extension steel frame of the building. Due to the limited available space for the stair several problems had to be overcome to gain the required head clearance height as you progress up the stair. This finally included moving the 1st floor exit of the stair location from where it was originally planned.
