Background
The White Tower is the most complete surviving 11th-century fortress palace in Europe and the most outstanding Norman keep in England.
Project Overview
Hockley & Dawson provided detailed structural design, advice and construction drawings for the new stair which involved 3D modelling and working within a highly experienced team in an extremely sensitive and historic setting.
Since its entrance is raised about 6.4m above ground level, it is likely a staircase was originally used to reach the doorway. The previous staircase, built in 1973, was removed in January 2015 after it was identified as a maintenance priority.
Norman design
Research and the initial design of the new set of stairs began in 2013 and the spring of 2014 saw the project team carefully select and fell the trees from Mapledurham Woods, near South Oxfordshire. The design of the steps has been informed by extensive research into Norman design and architecture.
Construction
The trees were shaped with axes in a process called hewing – a laborious practice rarely used today, but one which produces a genuine hand-worked finish.
