The Box is an innovative tool, intended to support "built environment professionals, activists, organisers, educators, enthusiasts, and policymakers" who are working to improve urban environments for their communities.

Materials – including posters, pocket-sized books, an issue of Cityscapes magazine, case study folios, a vinyl record, a deck of informational cards, and a board game – are contained in a sturdy but affordable box which is easily disseminated. The contents of the Box can be displayed as a small exhibition, and deployed as teaching aids and as tools for serious play. The aim is to prompt users to generate practical solutions to the problems faced by urban communities.

A4's Reading Room is an adaptable space attached to A4's Library and Archive. Intended to solve for form depending on its required function, it as at once a book-ish environment for reading and contemplation and a place to unpack artists' archives. The Reading Room's inter-leading doors become walls when locked to create a stand-alone spacial research studio that hosts residents and practices site-specific work that most-often is connected to packing and unpacking projects as a form of research.
