Mersey Chambers was built in 1878 for the Harrison Shipping Line in Liverpool, England, and designed by G.E. Grayson. It is a Grade II listed building.
It fronts St. Nicholas' churchyard, which was laid out as a public garden in 1891 in memory of James Harrison, a partner in the company.
The rear elevation to Covent Garden is a functional design with rows of oriel windows to admit maximum light. Inside, the offices are arranged around a glazed court.
There is a splendid panelled boardroom of around 1920, in classical style.
At the top of the building sits the 'third Liver bird', a smaller version of its more famous relatives.
