Salmond Reed was engaged by ASB Community Trust as conservation architects to oversee a major refurbishment of their offices located in the elaborate and conspicuous residential building, “Allendale”, at 50 Ponsonby Road. With its distinctive turret, Allendale is a prominent feature in the Ponsonby streetscape, and is scheduled by both New Zealand Historic Places Trust and Auckland Council. A corner bay villa of Italianate style dating from the 1890s, its construction combines both timber and rendered brick. Numerous alterations during Allendale’s lifetime, (including the lowering of ceilings in the ground floor), had resulted in haphazard levels of finish and inappropriate detailing. Salmond Reed’s recommendation was to undertake a complete retrofit of services, a seismic upgrade and restoration of as many heritage details as possible, including the raising of the ceilings and reinstatement of original spaces. The process also included total interior and exterior redecoration. This refurbishment process led the clients towards reanalysing their office accommodation and, as a result, Salmond Reed’s work expanded to include design of a new annexe building on an adjacent site formerly occupied by an earlier addition that was in poor condition and no longer fully met their space requirements. The new two-storeyed structure, housing an upper floor open plan office and modern well-equipped meeting spaces, provides a transition between the existing heritage building and the adjacent Ponsonby Road retail frontage and deliberately adopts a strong contemporary character to emphasise the architectural integrity of the original villa building. Outwardly restored and redecorated, Allendale House now integrates modern facilities, services, furniture and fittings that recognise their important heritage context, but speak equally of the villa’s contemporary function as a corporate head office.
