The entrance hall to Derwent building, the "old" Derby School, features a floor mosaic depicting the Derby School badge. However, in October 2010 a huge redevelopment scheme began to expand the college and buildings to connect the two parts of the college. The proposed removal of the mosaic to another part of the building was found impractical during the building's construction. It was covered in situ with cheap tiling and by October 2015 the gold paint used in the mosaic work is showing serious deterioration. is starting to affect the floor detrimentally.
