The Collins Street leg has an angled kink because the site narrows part way up due to the presence of a narrow laneway on the west side. Originally known as Carpenters Lane, the City Property Co successfully petitioned to roof it, creating a covered access from the Block Arcade to Little Collins Street. This in turn led to the development of shops in the lane, which was soon renamed Block Place. In 1902, Royal Arcade, which has been a dead end, was opened through to Little Collins Street creating a covered walk from Collins right through to Bourke Street.
