16 Cook Street, Liverpool was built in 1866 and, together with Oriel Chambers on the city's Water Street, forms the complete work of Peter Ellis. It is a Grade II* Listed Building.
Built two years after the Ellis' Oriel Chambers, it shows a development of his style. It has been suggested that American architect John Root witnessed and was influenced by the construction of both buildings. Root studied in Liverpool at the time of construction.
The building, and Oriel Chambers, featured in the ITV (Granada / Tyne Tees) television programme Grundy's Northern Pride, looking at John Grundy's favourite buildings in the north of England, aired on 9 January 2007.
