ROMA 3 – URBAN MORPHOLOGY COURSE second semester 2022


















FOR INFORMATION,  mail     gstrappa@yahoo.com


The course in Urban Morphology, optional, in English, provides 6 credits and is open to all students, including Erasmus ones.

The purpose of the morphological studies proposed by the course is the knowledge of the characters of the built environment and the recognition of its formation and transformation, having as ultimate goal the architectural design open to multiple esthetic synthesis.

It aims to teach a method of reading the physical form of the city through the understanding of the forming process common to urban fabrics and buildings, The term “reading” not indicates the neutral recording of phenomena, but an awareness which requires the active and dynamic contribution of the reader.

The basic notions of urban organism and forming process will be provided.


The course will consist of:

  1. a series of lectures (see schedule) aiming to provide the student, through the morphological/processural method, with the tools to read the built environment, historical and contemporary, having the architectural design as its goal. Some independent lectures could be given by external professors or experts, on complementary subjects.
  2. “morphological walks”. Field surveys organized to examine in the Rome historical center the fabrics and buildings under study.
  3. Students who intend to apply the reading method through a simple design proposal (exam form 1, see above), will be followed weekly through work reviews by the teachers.


Students will be evaluated through an oral test. They will choose one of the following forms of exam:

  1. Discussion of a simple design proposal derived from the theoretical studies.

Documents required:

  • study plan of the morphology of the place
  • study plan describing the formation of the proposal by phases
  • Plan of the design proposal (at urban scale) derived from the morphological reading and architectural interpretation of the place.
  1. Discussion on one of the theoretical topics listed in the course program.

The students will be free to present their individual notebook and all the works they consider useful for evaluation.

Giuseppe Strappa








Duilio Cambellotti,  L’inizio (The beginning).

The awareness of being able to use primary and universal characters in new architectural organisms, built with innovative techniques, responding to new needs and aesthetic values, constitutes the essence of the transition of European architecture to modernity. Buildings constructed according to these principles represent the vast majority of the renewal of cities in the first forty years of the XXI century. The modern movement experiments, even if useful to explore new ways, are, in fact, a minor and not fundamental part in the real urban transformations, above all in the areas of more rooted masonry-plastic culture.
This explains. for example, how it was possible such an evident continuity in the development of architecture in Italy in the interwar period, even in political conditions inducing a rhetorical interpretation of the historical heritage.
These are durable building organisms, using architectural layouts that are still vital precisely because they have not conformed, over time, to a specific function. They are “generic” organisms in the etymological sense of the term, capable of generating whole families of multiple, new architectures.
Many modern buildings (such as universities, schools, postal buildings) tend in different ways, in continuity with historical processes, to form a society of solidary spaces linked by a common purpose and a common rule. This rule is indirectly derived from the transformation of fabrics, through the permanence of typical structures such as convents or palaces. The beginning of this modern process can be clearly identified in the “urban necessity” of linking the building to the external paths, tightening it, at the same time, around an open space that tends to become the true nucleus of the forming process.
