The book Informal is out of print in some regions but available used (~$50–100) or via academic libraries. The PDFs circulating are often low-resolution scans missing key foldouts.
The book is not numerically indexed by standard chapters but by concepts. "Section 12" (found approximately halfway through the book) deals with . Here, Balmond analyzes the failure of the twin towers of the World Trade Center (pre-9/11) not as a tragedy but as a structural lesson in "redundancy vs. rigidity."
Enabling the realization of complex, non-standard forms. cecil balmond informal pdf 12
Cecil Balmond’s Informal bridged the historic gap between the architect's vision and the engineer's calculation. Before its publication, engineers often simplified complex architectural designs. Balmond proved that engineering could actively inspire form, rather than just support it.
In Informal , Balmond writes, "We have been brainwashed by the straight line." He invites us to look at nature, which never builds in right angles. Nature is recursive, self-similar, and fractal. Balmond’s work seeks to bring this natural complexity into the built environment, transforming engineering from a science of support into an art of narrative. The book Informal is out of print in
Instead of fixed grids, Balmond introduces the concept of the "trace"—the path of a moving point or force. By tracking these paths, designers can create patterns that evolve across a surface. These patterns distribute loads fluidly, allowing for lighter, more efficient material use. 3. Local Rules vs. Global Control
His influence can be seen in the work of a new generation of architects and engineers who embrace complex geometries, computational design, and the blurring of disciplinary boundaries. The "Informal" approach has also been the subject of numerous academic studies, including analyses of his patterning processes, his relationship to the philosophy of Gilles Deleuze, and the collaboration with Rem Koolhaas. The theory of the "Informal" continues to be a vital framework for understanding contemporary architecture's most ambitious and challenging forms. "Section 12" (found approximately halfway through the book)
Traditional engineering dictates a top-down, "global" order where the entire building follows a singular, strict layout. Balmond proposes a "local" logic. By allowing individual elements to react to their immediate surroundings based on simple rules, a complex, unpredictable global form emerges naturally. This mimics patterns found in nature, such as the growth of crystals or the formation of snowflakes. 3. Algorithms as Design Tools
Informal is considered a foundational text for contemporary parametric and computational design.
Balmond argues that the X-Y-Z axis system creates "dead space." He proposes structures that twist, turn, and overlap, creating "vibrant space."
The book acts as a manifesto for structural engineering that blurs the line between architecture and science. Key themes often discussed in academic papers and excerpts include: Amazon.com The Informal Manifesto
