In this building, two of the areas of architecture and construction which seem to be preferred in the coming years meet: the rehabilitation of the existing heritage and the use of elements that make a bridge with the construction industry, both of the structural elements and perimeter closures.

In this case, with the added complexity of inserting an Early Childhood and Primary Education Centre teaching programme into the container formed by one of the warehouses of the AEG industry that is included in the catalogue of heritage buildings in Terrassa.

The construction of the AEG factory complex in Terrassa was carried out on land given by the municipality in the early 1940s. In 1970, the AEG factory reached its peak with 1900 workers. 1981 is considered the beginning of the decline in its production until its final closure in mid-2005.

It is composed of tall prismatic volumes topped by a roof in the shape of a saw tooth. A small stone moulding separates this prism from the skylights. The structure is made up of three large single-span reinforced concrete porticoes. This powerful structure frees up a large open and well-lit interior space.

The interior space is defined through the vertical accesses over the central space. It is a succession of open stairs that, located one after the other, tighten the central space.

It is a space that moves in an ascending saw pattern that connects two successive double spaces located between the ground floor and the first floor (building B5) and the first floor and the second floor (building B3), open to each other and which allows a volume that would remain unused due to lighting and ventilation difficulties. This area becomes the central piece of the entire rehabilitation, achieving a space with characteristics that can only be found in interventions of this type.

The project wants to emphasise the recovery of the old AEG building for the new school use. Therefore, it proposes a rigorous respect for the formal, constructive and material characteristics between the existing parts and those of new construction.

The cladding materials for the façades will therefore be exposed brick in the rehabilitation and renovation of the façades of the B3 and B5 buildings and exposed brick façades, precast concrete panels and transparent glass and UGlass in the extended parts.

The dissonance between both parts will allow the eye to distinguish the general concept of the intervention, giving the complex two types of perception, texture and light. The inexpensive original materials will contrast with the contemporary translucent facings, signaling the entrance and creating an incandescent lamp at night.

The project proposes intensive use of the two heritage buildings, locating most of the general and Primary Education spaces there. On the opposite side of the plot there is the Children's Area, with independent access for parents from the back street.

Hall. The entire programme located in the rehabilitated buildings is located around a large interior patio-atrium located in the central corridor of these buildings. It is a space that moves in an ascending saw pattern that connects two successive double spaces located between the ground floor and the first floor (building B5) and the first floor and the second floor (building B3), open to each other and which allows a volume that would remain unused due to lighting and ventilation difficulties. This area becomes the central piece of the entire rehabilitation, achieving a space with characteristics that can only be found in interventions of this type.
