 The library design incorporated several notable features, including the maximisation of natural light, the use of recyclable material, including reuse of grey water, and a natural ventilation and cooling system to limit energy costs.After the Environment Court decision (see below) this design underwent some modification, but the library opened on 17 December 2009 with a formal opening ceremony in February 2010.In preparation for a new community library complex the old Birkenhead Library was demolished in May 2005.
