The Pier was designed and engineered by Eugenius Birch to attract visitors and survive in the hostile environment of the seashore. Built in 1866, it was a simple and functional structure built out from the sea using dozens of cast iron threaded columns screwed into the seabed and strengthened by a lattice of ties and girders that provide the necessary strength to support the promenade deck whilst allowing seas to pass harmlessly through.

Originally the West Pier had an open deck with only six small ornamental houses of oriental design, two toll houses and glass screens at the pier head to protect visitors from the wind and sun. In 1875 a central bandstand was added. In the 1880's weather screens the full length of the pier, steamer landing stages and a large pier head pavilion were constructed.
