Learning unit contents

The course consists of two parts:

- the first provides the general historical and conceptual framework for interventions on existing heritage buildings (History and theories of intervention on existing buildings - C. Houbart),

- the second focuses on interventions on 20th-century heritage buildings, through a detailed examination of specific examples and issues (20th-Century Heritage - M. Cohen).

See the specific teaching commitments for details of both parts.

Histoire et théories de l'intervention sur l'existant

The course takes a chronological approach to examining the evolution of the principles and practices of intervention in existing built heritage throughout history (from antiquity to the present day, with a focus on the contemporary period). It is organised into nine chapters:

1. Existing buildings as a resource

2. The French Revolution and the emergence of the 'Monument historique'

3. Restoration and anti-restoration in the 19th century

4. The search for a compromise at the turn of the 20th century

5. The First World War and the Athens Conference

6. The Second World War and the case-by-case approach

7. The Venice Charter, ICOMOS and the globalisation of the debate

8. Use value, integrated conservation and adaptive re-use

9. The holistic approach and Critical Heritage Studies

Each chapter covers the historical context, the key players involved in interventions on existing built heritage (institutions, organisations, architects, archaeologists, critics, etc.), the concepts and principles of intervention developed, as well as a selection of examples. Text readings, compiled in an anthology and/or posted on e-Campus, supplement the course material.

Patrimoine du XXe siècle

This part of the course is devoted to 20th-century architecture, the problems that arose during this period, and the solutions devised.

The subject matter is illustrated by several case studies that help students understand the complexity of the processes, choices and proposed solutions, whilst highlighting the evolution of restoration techniques.

A general introduction to the subject aims to trace the development of this aspect of the architectural discipline and the numerous issues that have gradually emerged as a result of changing standards, environmental problems, changes in use, the ageing of materials and planned obsolescence.

Particular emphasis is placed on methods for identifying and assessing the value of properties in order to determine the steps to be taken for their potential preservation.

Unlike the 'heritage' of previous eras, a large proportion of 20th-century buildings are the result of experimentation, which requires equally innovative conservation measures.

 

 

Learning outcomes of the learning unit

By the end of this course, students will be able to

- define and apply the basic concepts and principles that have underpinned interventions on existing buildings throughout history;

- use specialist terminology;

- understand the issues at stake in current debates regarding interventions on existing buildings;

- take a critical look at current and past conservation, restoration and adaptive reuse projects;

- have a firm grasp of the conceptual framework applicable to interventions on existing heritage buildings.

- take a critical look at current and past conservation, restoration and adaptive reuse projects;

- have a firm grasp of the conceptual framework applicable to interventions on existing heritage buildings.

Patrimoine du XXe siècle

The learning objectives are to gain an understanding of heritage issues relating to the 20th century, as well as of deterioration processes and conservation methods.

Other objectives include understanding the value systems that determine the work to be carried out as part of a conservation, restoration or renovation project.

The course also aims to place the case studies within their historical context and to understand the decisions made regarding their treatment, as well as the debates they sparked.

Assessment methods and criteria

Exam(s) in session

Any session

- In-person

written exam ( multiple-choice questionnaire, open-ended questions )


Further information:

To be awarded credit for the teaching unit, students must achieve a minimum mark of 10/20 in each of the course components: ARCH3333-A-a (History and Theories of Intervention in Existing Buildings) and ARCH3333-B-a (20th-Century Heritage).

If a student achieves a mark of less than 10/20 in one (or both) of the course components, their overall mark will be reduced to the lowest mark obtained (the 'absorbing mark' principle).

If the student achieves at least 10/20 in both components, their overall mark will be the average of the two components (50 per cent for each component).

Carrying over a partial mark of less than 10 from one session to the next is not permitted.

Organizational remarks

From the 2026-27 academic year onwards, the 'absorbing mark' principle will be applied to the assessment of the course components.

Generally speaking, Part 1 takes up the first two hours of the lesson, and Part 2 the last two, although exceptions may apply. A schedule of sessions is kept up to date via eCampus.
