The scheme will convert the five-storey, 1870 landmark - which is currently on English Heritage's Buildings at Risk register - into a 15,000m2 office complex with space for up to 1,500 workers.
To overcome this ASL has designed a new glazed roof and atrium space to allow natural light into the centre of the development, which will later include a four-star hotel, retail and leisure space.
Clive Panter, director with ASL, said: 'Creative reuse of historic buildings is always a challenge, and the Grade II-listed warehouse is no exception. Its prominence upon arriving by train in Huddersfield, and proximity to the Grade I-listed station building, require any proposals to be sympathetic to the existing architecture.
'The scheme therefore proposes minimum interventions in the existing fabric.'
