Jetset House - Edward St.  112metres, 30storeys.  Completed in 1979.
 
This building blatantly blocks City Hall's majestic clock tower and basically all other landmarks surrounding it, like the Salvation Army Headquarters (now backpacker hostel).  The sun-shade devices over the window look like plastic or fibreglass that have tarnished over the years.
