    There are Australian Standards on car parking. I can’t quote precisely but I did read much of it a few years ago. One principle in carpark design is that a space should be wide enough to open the car doors. If the space has a wall or other tall object adjacent then the space must be wider than if it can be assumed that a few 100mm can be ‘borrowed’ from an adjacent parking space. Consequently, end spaces against a wall might be a minimum of 2.7m wide to meet the standard whereas the spaces with other spaces to either side might be 2.4m minimum. 

    So, putting a cupboard up within one parking space along the boundary could be interfering with reasonable use of the adjacent parking space. 

    I also recall a complex diagram showing that, if the spaces were not of constant width, they could be narrower at the nose end so long as they were wide enough around the middle where the doors tend to be. So, a short cupboard, not full length, might be OK along a parking space boundary. 

    I would say that if the space is less than 2.7m wide, erecting a vertical barrier along one side would cause that space to no longer comply with the Australian Standards on parking and that would provide objective reason by which to decide that the cupboard placement is causing unreasonable interference.
