The renovation of four disused factories in Hangzhou forms part of the main urban core for a new city centre.
The preservation of the central hall and its concrete trusses is complimented by a newly glazed roof lantern.
To provide additional floor area while preserving the grandness of the original factory new program is placed in a ground level plinth.
The undulating plinth frames the existing factory building while referencing the landscape of Hangzhou.
By rethinking the idea of the mat building as a plinth the new urban core can be one based on the void rather than a hyperdense building.
