Design in Detail

KPF’s practice is rooted in the conviction that an ambitious design concept is most successful when its underlying intentions are thoughtfully and rigorously developed through all stages of a project, its original thesis embodied in its materials and details.

Note 01

This essay has been adapted from a lecture delivered by James von Klemperer, KPF President and Design Principal, at Tsinghua University in Beijing. The event, occurring in May 2018, accompanied the very first iteration of the firm’s traveling exhibit, hosted within the university’s architecture school.

Too often, the execution of contemporary, large-scale architecture suffers from a widening gap between theoretical intention and physical realization. The formidable rigors of managing schedules, budgets, and logistics often results in a division of labor between design and construction, eliminating the traditional, broader role of the architect as “master of all trades.”

At KPF, we endeavor to create more integrated, holistic architecture by prioritizing continuity between conception and completion. The patterns of traditional bricklaying, the logic of wood joinery, and the modern technologies of newly invented materials all inform our building concepts.

Without delving into an exhaustive survey of architectural history, this essay considers a few significant moments and figures throughout the history of architecture that have irrevocably shaped contemporary practice.

To better understand the relationship between idea and execution, it helps to ask how the role of the architect — as designer, maker, and builder — has evolved over time.

Beginning in fifteenth century Italy, perspective drawing gave architects new tools with which to conceive of space, with Fillippo Brunelleschi representing a certain ideal of the “total architect.” Although he is most famous for designing the Duomo in Florence, he started his life as a craftsman. His technical talents as a metalsmith informed his work at the architectural scale. He designed not only the Duomo’s structure of compressive parabolas and chain tension rings, but also its scaffolding and a new system for hoisting masonry up the structure. Based on his understanding of productivity, he even prescribed what and when the workers should eat and drink.

Later periods experienced a continuous series of pendulum swings between “integrated” and “separated” practice. Notably, the increased mechanization that accompanied multiple industrial revolutions posed challenges to the tenets of a humanist approach. From the early nineteenth century onwards, European factories established new standards of production efficiency. The inherent conflicts between craft and the growing industrial machine raised fundamental questions for both theorists and practitioners of architecture.

Theorists such as John Ruskin, A.W.N. Pugin, and William Morris championed the English Arts & Crafts movement and critiqued the industrial age for its detachment from traditional craftsmanship. They praised vernacular, material culture, made possible by the architect engaging in design to its fullest extent. The ideal “craftsman-designer” would link the design of fabric, furniture, and lighting with the process of fabrication in order to create a more meaningful living environment.

In the early twentieth century, several German philosophers, and the members of the Deutscher Werkbund, proposed that design embrace its role in the industrial process. The AEG Turbine Factory (1909) is a prime historical example, demonstrating that industry could be at once interesting and beautiful. The AEG lightbulb is one example that illustrates this industrial design movement.

Later, the Bauhaus epitomized some of the greatest outcomes of this marriage between art and industry. Walter Gropius, the school’s founder and historical figurehead, praised the total work of art — or “Gesamtkunstwerk”— for including architecture as a master discipline. The Bauhaus curriculum and coursework, depicted as a wheel-like diagram, incorporates formal studies, such as painting, while also exploring materials and building science. This approach to industrial craft influenced notable buildings of the day, reinforcing a modern notion of the architectural profession.

The legacy of the architectural profession continues to influence KPF’s present work and future efforts, bringing the issue of process front and center with every project, no matter the scale. Our architects challenge each other to be ambitious in their “big ideas” while still considerate of every material decision, even when technologies introduce new schisms and widen existing ones. These tensions inspire an architectural practice that balances design and making, with craft at the fulcrum.

This completed project in Hong Kong exemplifies the balance of craft and nature in one of the world’s most active cities. The project includes luxury townhouses perched between a dense, urban context and articulate landscaping, inspired by icons of Chinese culture and history such as the Great Wall, the folding screen, and the dragon dance.

The distinctive street wall includes handcrafted, cast bronze privacy screens and door details for each unit.

KPF commissioned a local artist to design these screens, selecting bronze for its richness and warmth, and testing more than 20 alloy mixtures to produce the desired color effect: a balance between dark brown and gold, pale and overly saturated. This practice also required anticipating the material’s patina and its inevitable oxidation.

With a shared goal for the bronze to age beautifully, the team chose to forego any application of polymer that would fossilize the metal, meaning that the bronze would lack visible luster but remain stabilized. Acknowledging the reality of maintenance for this level of detail, the client committed to applying beeswax regularly, which seals the bronze from any contact with oxygen.

Rippling bands of glass mediate the varied scales and formal language of New York, creating a sense of movement along the street wall and reflecting the buildings and activity of the Village back to its surroundings. KPF replicated this effect within the residential building’s dramatic entrance through the innovative use of bamboo paneling.The expansive lobby suggests a block of wood, worn over time by the ebb and flow of residents, much like a river erodes its banks.

The expansive lobby suggests a block of wood, worn over time by the ebb and flow of residents, much like a river erodes its banks. Initially considering limestone, the design team instead gravitated toward bamboo for its luxurious yet organic qualities. Working closely with SITU studio, KPF determined how strips of CNC-milled bamboo would stack to extend height of the 18-foot lobby.

The first layout produced a dizzying, psychedelic effect, while the final design solution prioritized consistency in the wood grain with thin, horizontal lines that stretch the width of every piece. Slender, stainless steel verticals connect each panel, accenting the slight sheen of the bamboo.

A tenet of KPF’s early practice was that large buildings can express the intricacies often reserved for smaller structures, and diligent attention to this idea pervades KPF’s ethos today. Many of the firm’s most beloved projects employ a single detail reiterated by its overall gesture. This pledge persists and ensures that ongoing work achieves physical longevity and contributes to the overall built environment.
