An adaptive reuse project filed for North Sydney will save thousands of tonnes in carbon emissions, according to its proponents. 

Maville West, an entity associated with wife-and-husband team Zhiling Mai and Xinan Shen according to ASIC documents, has filed plans to transform a 1970s brutalist office block into a residential apartment building. 

The project on the 1814sq m site at 8 West Street would save an estimated 3577 metric tonnes of carbon dioxide in the construction phase, according to development application documents.
