In observing the underlying design strategies that have enabled this and other seamless extensions of space, I will distinguish between attempts to create architectural extensions and designs that aim towards spatial relocation, arguing that in juxtaposing material and immaterial elements, designers today face similar challenges and opportunities to those Sergei Eisenstein addressed through his concept of spatial montage in 1938. Eisenstein regarded architecture as the predecessor to film and he often compared the three-dimensional capacity of the new media with that of architecture: ‘The Greeks have left us the most perfect examples of shot design, change of shot, and shot length’. (Eisenstein ca 1938: 112).
