16 Cook Street, Liverpool is the world’s second glass curtain walled building.

Designed by Peter Ellis in 1866, it is a Grade II listed building.

Built two years after Oriel Chambers on Water Street, the architect’s best known work, it shows the development of Ellis’ style. Its floor to ceiling glass allows light to penetrate deep into the building, contrasting strongly with the adjacent structures. It has been suggested that American architect John Root was influenced by the construction of both buildings, having studied in Liverpool at the time of their construction.
