Blobitecture (from blob architecture), blobism and blobismus are terms for a movement in architecture in which buildings have an organic, amoeba-shaped, building form. Though the term 'blob architecture' was in vogue already in the mid-1990s, the word blobitecture first appeared in print in 2002, in William Safire's "On Language" column in the New York Times Magazine in an article entitled Defenestration. Though intended in the article to have a derogatory meaning, the word stuck and is often used to describe buildings with curved and rounded shapes.
The term 'blob architecture' was coined by architect Greg Lynn in 1995 in his experiments in digital design with metaball graphical software. Soon a range of architects and furniture designers began to experiment with this "blobby" software to create new and unusual forms. Despite its seeming organicism, blob architecture is unthinkable without this and other similar computer-aided design programs. Architects derive the forms by manipulating the algorithms of the computer modeling platform. Some other computer aided design functions involved in developing this are the nonuniform rational B-spline or NURB, freeform surfaces, and the digitizing of sculpted forms by means akin to computed tomography.
One precedent is Archigram, a group of English architects working in the 1960s, to which Peter Cook belonged. They were interested in inflatable architecture as well as in the shapes that could be generated from plastic. Ron Herron, also a member of Archigram, created blob-like architecture in his projects from the 1960s, such as Walking Cities and Instant City, as did Michael Webb with Sin Centre.Buckminster Fuller's work with geodesic domes provided both stylistic and structural precedents. Geodesic domes form the building blocks for works including The Eden Project. Niemeyer's Edificio Copan built in 1957 undulates nonsymetrically invoking the irregular non-linearity often seen in blobitecture. There was a climate of experimental architecture with an air of psychedelia in the 1970s that these were a part of. Frederick Kiesler's unbuilt, Endless House is another instance of early blob-like architecture, although it is symmetrical in plan and designed before computers; his design for the Shrine of the Book (construction begun, 1965) which has the characteristic droplet form of fluid also anticipates forms that interest architects today. Similarly, one would have to include the work of Vittorio Giorgini (Casa Saldarini), Pascal Haüsermann and especially that of Antti Lovag as examples of successfully built blobs. The latter built the famous Palais Bulles close to Cannes on the French Côte d'Azur, owned by fashion designer Pierre Cardin.
