The Dublin, Manchester and London-based architect won the commission to redesign Deptford's Seager Distillery after McAslan was dropped from the project.
McAslan claimed that the move came after the building - now owned by developer MacDonald Egan - was sold by its original owner.
HKR plans to build a low-rise building on the site, as opposed to the distinctive high-rise development previously proposed by McAslan ( pictured).
MacDonald Egan currently owns the planning consent, won by McAslan, for 25,000m 2of mixed-use development, including 219 residential units and 4,500m 2of commercial space.
According to the developer, London mayor Ken Livingstone once described its proposals as 'an exemplar of process and design in London'.
