projected structures are usually not allowed by the councils, however the building developer management negotiated terms with the melbourne council to lease the air space. this created limits on how far the extrusions were allowed to protrude but nonetheless increased the usable floor space of the units. the balconies of the cloud apartments project out at up to 3 metres in length as they are within the land's boundaries and are not hovering over the pedestrian walk. the carlton residents association also campaigned for the building to not exceed 15 storeys despite the intents for a 19-storey complex, both sides came into an agreement for a total of 17 levels.
