Mantra Group has opened its first Art Series Hotel – The Chen in the Melbourne high-rise suburb of Box Hill – after settling on its $52.5 million acquisition of the chain of designer boutique hotels developed by the wealthy Deague family.

The new 100-room hotel, named after Chinese-Australian abstract artist Zhong Chen, forms part of the Deague Group's recently completed Whitehorse Towers, the tallest residential building outside of the Melbourne CBD comprising 511 apartments across two towers of 36 and 24 storeys.
