A new development project to the south of the existing building will transform Tate Modern.

This 11 storey pyramidal stack is surprisingly a glass clad building with a brick façade supported on a metal exoskeleton 200mm from the glass cladding.

Special bricks are needed to lock onto the exoskeleton and to allow light through the brick skin. Of the 330,000 special blocks required, it was not cost effective on 10,000 blocks to extrude the perforations at the factory. Brick Cutters were retained to drill 25,000 holes in these 10,000 blocks, check, label, pack, wrap and deliver to site as work proceeds.
