Now that all of the original straight sections in the Diamond storage ring are occupied, novel ways of converting bending magnet beamline locations into insertion device beamlines have been considered. Recently one cell of the 24 cells was reconfigured in to a Double-Double Bend Achromat (DDBA) to provide a new location for an Undulator and enable a formerly designated bending magnet beamline to become an Insertion Device Beamline*. Extending this concept for the new Dual Imaging and

The accelerator physics, mechanical and electrical design aspects associated with the change are described.
