The Velocity Tower stands 22-storeys high beside the roundabout at the junction of Moor Street and St. Mary's Gate.  Apparently, the building was originally designed by Broadway Malyan but the project stalled and looked for a while as if it wouldn't proceed.  When it was revived by Cala they turned to the Sheffield based architectural practice of Axis Architecture to make some modifications.  The changes included, "the introduction of a high-quality glass cladding façade to replace the previously proposed brickwork skin. A taller ground floor was also introduced, and a roof top wind turbine array was added to improve the buildings green credentials."  When these photographs were taken in October of 2011 the second phase of the building remains unfinished.

The nature of the planned building can be gathered from the Axis Architecture website.  They say that, "Axis's proposal for this 30 storey residential tower with an 18 storey apart hotel next to it has changed the Sheffield skyline and introduced new construction techniques to accelerate the build time.  Scheme comprises 120 studio apartments and service offices with conference suite on the impressive double height floor."  Clearly the tower has been reduced by 9 floors and the apart hotel and serviced offices are yet to be built.
