"Balmond’s Chapter 12 is a poetic, frustrating, brilliant sketchbook of ideas. It will not teach you how to engineer, but it will change how you think about engineering."
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.
Traditional architecture relies on "formal" systems—Platonic solids (cubes, spheres) and rigid, Cartesian grids. cecil balmond informal pdf 12
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 illustrates these abstract theories through real-world architectural masterpieces. Balmond’s structural engineering turned radical concepts into physical reality. The Bordeaux House (with Rem Koolhaas / OMA)
Why does Informal remain relevant today? In an era of parametricism and AI-generated design, Balmond’s work serves as a reminder that complexity requires a soul. Balmond proved that engineering could actively inspire form,
This residential masterpiece features a massive, cantilevered top floor. It appears to float effortlessly in the air. Balmond achieved this by misaligning structural supports and using a hidden steel track. This challenged the conventional logic of gravity. The Serpentine Gallery Pavilion 2002 (with Toyo Ito)
The book is renowned for its intimate presentation of Balmond's creative process. It is filled with hundreds of his personal sketches and diagrams, which are not merely technical illustrations but the very key to his approach. These drawings reveal a mind at work, exploring geometry, numbers, and pattern. The book's design is deliberately "informal" itself, with a free-form layout that mirrors its content. As the New York Times noted, it is "A Koolhaas-slick monograph with his own manifesto-style meditations on everything from fractal geometry to Victorian tiles". Other critics praised it as "a beautifully constructed book" that changes how you see buildings, and even compared it to "the next Brief History of Time - but with pictures".
