The Venetian Facade

The Venetian Palace is to the art of the facade as the French Hôtel is to the art of the plan—the quintessential level of architectural achievement. Unique in the history of architecture, and a product of an equally unique circumstance, the Venetian facade is almost modern in its planar abstraction and lack of structural expression.

This book is about architecture; it is not about history, it is not about theory, it is not about structure and technology, and, most definitely, it is not about the plan. All of these topics are well-covered elsewhere. This book is about the facade. It explores the art and typology of the Venetian facade, not only as a high point of architectural literacy and achievement, but as a potentially useful contemporary stimulant.

Book cover for "Urbanism as Civic Art: A Handbook of 150 Exemplary German Precedents" by Christoph Mäckler with Birgit Roth, published by the University of Notre Dame School of Architecture Ratio et Architectura.

Urbanism as Civic Art

Urbanism as Civic Art presents essential expertise on the art of building cities. Showcasing 150 examples from over 70 German cities, it illustrates, analyzes, and compares a wide range of city spaces, courtyard spaces, plaza spaces, and street spaces. The book impressively documents the distinctive qualities of European cities: their beauty, durability, mixed usage, social diversity, density, and the clear separation between public and private space. Editor Christoph Mäckler builds on the foundations laid by early twentieth-century urban design pioneers such as Cornelius Gurlitt, Raymond Unwin, and Josef Stübben, offering a comprehensive framework for city planning.

The works of Joseph Brix and Felix Genzmer, Cornelius Gurlitt, Camillo Sitte, Josef Stübben, and many others helped establish Städtebau-urban design, or the civic art of building cities as a field of study focused on the architectonic shaping and planning of urban spaces, even at the turn of the twentieth century. The necessity of reintroducing this craft as the foundation for designing contemporary urban districts inspired the creation of this handbook, first published in 2022. The release of this English translation reflects the strong interest in the publication, which has sold nearly one thousand copies.

Edited by Christoph Mäckler and Birgit Roth with contributions from Vittorio Magnago Lampugani, Werner Oechslin, Alexander Pellnitz, Anna Pfeil, Jan Pieper, Stefanos Polyzoides, Mirjam Schimdt, Wolfgang Sonne, Jürg Sulzer, and Thomas Will.

Court & Garden: From the French Hôtel to the City of Modern Architecture

The French Hôtel, an aristocratic Paris townhouse, is to the art of the plan as the Venetian Palace is to the art of the facade—the quintessential level of architectural achievement. The development of the hôtel between approximately 1550 and 1800 chronicles the formal transformation from an embedded urban building type to a free-standing suburban building type; it also illuminates the social transformation from total emphasis on the public realm under Louis XIV, to the dominance of private life in our time. In contrast to the principles of continuity and regularity of classical buildings, the design principles of the hôtels were based on discontinuity and irregularity, allowing freer, more adaptable architectural compositions. The French Hôtel is a direct ancestor of the modern “free-plan,” thus enabling a rich contemporary architectural vocabulary.

Brick by Brick: Traditional Brick Fabrication in Present-Day Practice

Brick by Brick preserves the specialized material knowledge of Fornace Bernasconi, an artisan brick factory in Castel Viscardo whose craftsmanship is essential to the restoration of Italy’s most significant Roman monuments. This publication synthesizes advanced digital surveys, including FARO laser-scan data, with analytical hand-drawn illustrations to document a generational process that is rapidly disappearing from global building culture. By analyzing the intersection of local geology and traditional structural mechanics, the work provides a technical bridge between contemporary architectural design and the fundamental principles of masonry. It serves as both a vital archival record and an instructional resource for understanding the resilient, tangible aspects of traditional craftsmanship.
