This issue of AD explores the working discipline of architecture as it impacts the material culture within which it is always embedded. An architecture of impact uses advanced digital techniques in such a way that its material assembly supersedes its use of the digital. Until now, this type of architecture has been formally and materially bound by restrictive conventional methodologies, which the digital project has moved from the scale of installations to three-dimensional building-sized fabrications. Unless architects turn to a new culture of making, architecture shaped by even innovative digital technology will become irrelevant. Architectural projects that are more subversive in how they are created and that lose their digital signature have greater potential to be at the forefront of the discipline's new materialisations. This issue illustrates these ideas and their architectural impact.
