The subject (6 ECTS credits) is located in the compulsory module of the first semester of the second academic year. The teacher responsible for the subject is Dr. architect Jordi Roviras Miñana, with the practical support of teachers and architects: Cristina Garcia Castelao, Ignacio Morente and Ricardo Gómez Val.
The course tries to influence the knowledge of the materials. The student is faced with the problem of making an idea realizable starting from the consideration of generic elements that allow the introduction of the requirements that generically condition any constructive experience within the scope of the horizontal enclosure: The roof.

The main purpose of this course is to bring the student closer to the intervention of these roof spaces (the 5th facade of the building), learning the construction techniques necessary to design spaces that emphasize or even revalue the architecture of the own building (a good example is the Santa Caterina market in Barcelona made by the EMBT architecture studio). That is why it is necessary to learn the different construction typologies of a roof and the different uses they can have depending on the program of use (walkable, non-walkable, landscaped, cistern, etc.) At the same time, the course aims to teach the 'student/ to all those basic requirements and elements that intervene in the definition of a project of this type: Drainage systems for sinks, thermal insulation, waterproof sheets, vapor barriers, lightweight concrete for the formation of eaves , finishing and finishing materials, etc.

The aim is to encourage self-learning of construction with an emphasis on drawing as a tool for reflection and verification and as a means of learning how to read and assimilate construction terms.
