Newspaper clipping about an extension to be built behind the historic house at 99 Hotham Street, East Melbourne. As a way of working around height restrictions some developers are finding extra floor space underground. This development includes a two level basement which will include a squash court, cellar, gymnasium, sauna, steam room and six car garage with a vehicle lift. Graham Shepherd, speaking for the East Melbourne Historical Society, warned that the development could cause disruption to the water table which in turn could have major consequences for neighbouring properties. Includes photo and diagrams.
