It is a striking building best imagined as an inverted capital letter 'L', with the upper part supported by thin steel pillars set at apparently random angles. The exterior is clad with pre-patinated copper.[1][3]
The Stirling Prize judges were impressed with the building's approach. Alsop has taken the plan footprint of a conventional library and elevated it to create a public space beneath the building and to remove the quiet reading space from street level noise. The remaining, supporting buildings on the ground and 1st floors house the information and media centre.[citation needed] The building has five floors in total, with the library service taking up the fourth floor.[3]
The building attracted 500,000 visitors in its first year of opening in the wake of its receipt of the prize. This dropped to approximately 420,000 for 2006.[citation needed]
SuperC [de], a student service centre building at the RWTH Aachen in Germany was built in 2006, which has been compared to Peckham Library with a similar L design.[citation needed]
