Prefabrication experiments - 177 - Geometries - 08 - Hexacube and plastics in architecture

Modernity in architecture in pre World War II social and manufacturing reforms evolved into 1960s and 1970s high modernism. Military technology and the ensuing space race inspired visionary architecture. Plastic production garnered particular interest to commodify architecture’s production as it had done for other consumables. Simple to produce shapes and objects became the source of combinable and coordinated architectural components. George Candilis proposed the Hexacube in the early 1970s employing matching and stackable fiberglass reinforced shells to form dwellings. The cube facilitated clustering while hexagons were used to match cube faces together.

Many such projects developed concurrently for different scales and different settings. The DO-bausystem in Germany, the Tetrodon in France, Guy Gérin Lajoie’s modular plastic panels for the Arctic in Canada and the Ventura and Futuro houses by Matti Suuronen in Finland all employed similar systems casting fiberglass reinforced plastic components for producing buildings. Units or panels could simply be snapped or bolted together streamlining construction. The Hexacube’s basic unit was a moulded half cube, which could be employed as the upper or lower part of the cube. Each 5 m3 cube was moulded with half-hexagonal shaped openings, which formed full hexagons when the half cubes were matched. The hexagon opening acted as the hexacube’s reproductive organ; their alignment and subsequent affixing made it possible to achieve multiple arrangements.  The openings could be adapted with a series of facades or functional hexagonal shaped units, varying the Hexacube’s function and appearance. A series of accessories, rectangular prisms half the size of the cube programmed by function, hygiene, storage, kitchen or other services, could be plugged into the basic unit creating an infinite number of patterns and uses. Each half cube could be piled for efficient delivery, eight deep, as one would stack plastic utility chairs. The cube’s edges were tapered and chamfered to facilitate casting and recasting using the same moulds.


Dubigeon Platics produced Candilis and Anja Blomstedt’s hexacube in 1972. Although only a marginal number of units were produced, the system showcased a manner in which knowledge transfer from the plastics industry to architecture made it possible to fabricate objects, architecture, and cities with similar processes.
