 His work Paddling Home , a 4 ft × 4 ft ( 1 @.@ 2 m × 1 @.@ 2 m ) floating house , was set to sea in January 2010 . The work , symbolising the Hong Kong 's property market where the accommodation is high @-@ density , small and pricey , was selected at the Hong Kong & Shenzhen Bi City Biennale of Urbanism Architecture exhibition that year . The design includes tiled walls , wooden floorboards , bay windows , a television , air @-@ conditioning , roof space from which to drive a few golf balls and a 5 @-@ horsepower outboard motor . It was priced at a symbolical HK $ 888 @,@ 888 ( $ 114 @,@ 000 ) . Wong said that , as the square foot price is [ an astronomical ] HK $ 55 @,@ 555 , Paddling Home is an ironic statement comparing the perils of owning a glitzily- and glossily @-@ packaged high end residence to being on the high seas . When asked in 2012 , Wong said he considers Paddling Home his most challenging work to date .
