In 2014, Álvaro Siza designed, with Carlos Castanheira the Building on the Water in Huai'An City, Jiangsu, China that was awarded the building of the year 2015 by ArchDaily.
In July 2014 Siza announced his decision to donate the large part of his architectural archive to the Canadian Centre for Architecture (CCA) in Montreal, Quebec, Canada, in order to make his materials "accessible alongside the work of other modern and contemporary architects", while also giving specific project archives to the Fundação Gulbenkian in Lisbon and Fundação de Serralves in Porto, Portugal.
