The project's approach takes advantage of the site's optimal conditions: facing southeast, isolated, elevated with respect to the communication routes, centrally located. The building is placed at the rear and respects the natural slope of the land, favouring maximum sunlight in the playground and on the main façade. The main body is divided into three bays: the front one, 6.40 metres wide, houses the classrooms. Each classroom receives light through two large windows with waterproof blinds. The second bay, 3 metres wide, is occupied by the corridor. And the rear bay, 4.75 metres wide, houses the complementary rooms.

A member of GATCPAC, Pedro Armengou was the municipal architect of Manresa and knew how to choose a site with excellent conditions for the construction of the school: south-east orientation, elevated in relation to the public thoroughfare, central location, ease of communication, etc. The project makes the most of these qualities by placing the building at the back of the site, thus obtaining maximum sunlight for the playing fields and the building. The main façade of the building faces southeast and all the classrooms face in the same direction.
All the principles of constructive rationalism have been respected: widened windows, simplicity of volume and use of a flat roof. The south-east façade is predominantly empty to the extent that it is almost all windows. From inside the classrooms one can appreciate the excellent location of the school complex and in the south corner there are two terraces that serve as outdoor classrooms. The classrooms are furnished with wooden tables and chairs, and the tables are of three graduated sizes to cater for the six year groups. A projection screen has been installed in the gymnasium. The decoration is very simple, of a rationalist nature.

The building is characterised by new rationalist ideas and is, in fact, the architect's most important work. Armengou was able to choose a site with excellent conditions for the project.

It is a four-storey building with a basement for installations. It is structured according to the criteria based on three parallel bays, oriented to the southeast to make the most of the land. The classrooms are located in the first bay, which faces the main façade and is 6.4 metres wide. In a second, central bay - 3 metres wide -, there is a circulation core that gives access to the different rooms. In the third bay - 4.75 metres wide - with a façade to the rear, there is a set of functionally auxiliary rooms for the building's activity or services. The building meets construction criteria considered basic techniques in current construction and therefore has a reinforced concrete structure. The enclosures are made of brick and the façades, plastered and painted, make no concessions to ornamentation.

All the criteria of constructive rationalism were respected in this work: simplicity in the volume, use of a flat roof and elongated windows.

The building was designed in 1932 by Pere Armengou i Torra, municipal architect of Manresa, and inaugurated in 1934. The ‘Renaixença’ school is this architect's most important work; he was also responsible for the design of some of the school furniture, following the criteria proposed by the Bauhaus. Subsequently, around 1968, a series of interventions were carried out which, although they substantially modified the work, respected its initial spirit.
