Clifford’s Tower, once the keep of York Castle, is a scheduled monument perched on a man-made motte. Timber was ideally suited for the new structure due to its low carbon impact and light weight properties. The raised location, limited access, steep slopes, and irregular geometry were some of the factors making the construction of the tower challenging; all timber components were designed so that they could be lifted in and connected on the site, using concealed connections.
The design features a timber deck which partially covers the interior of the ruin and is supported on four glulam timber columns. The architectural form celebrates the exposed timber structure with no unnecessary finishes. Timber was the ideal material for this project in keeping with the durability and low maintenance required for the design life of 50 years for the structure.
