Aura were appointed as specialist sub-contractors to undertake the external restoration works to 26 Cross Street as part of a wider refurbishment programme to transform the building into a ‘boutique style’ office environment with state of the art suites.
Designed by 5 Plus Architects, the historic 21,500 sq ft building was refurbished and restored with the aim to retain its Portland stone façade and period features in keeping with the street’s similarly designed historic buildings. Cross Street is located in St Ann’s Conservation area in central Manchester, the area is a stunning blend of the old and the new.
Aura’s contracted works for the project included installation of cathodic protection to the steel frame of the façade using the ‘impressed current cathodic protection design system’. This technique was used to stop the future corrosion of the internal steel structure. The building had previously been out of use for several years and subjected to years of water infiltration leading to corrosion to the structural steel frame which had subsequently caused increased pressure jacking to the external stone façade.
Aura’s works also included an extensive concrete repair scheme to the upper 6th floor reinforced concrete beams and slab sections. Following a hammer test survey identifying defects, works comprised of breaking out concrete to failed areas and introduction of repairs to reinstate the integrity of the structure.
Additional works were then undertaken to infill panels between windows, such as mortar repairs, removal of ferrous fixings and stone indents to upper dental details.
Aura are thrilled to have been involved in this contract to restore the Portland stone façade, making this building stand out amongst one of Manchester’s most historic and lively streetscapes.
