架构师提供的文本描述。干预的主要原则是根据原有结构和内部空间布局最初提供的可能性，对现有建筑进行内部功能改造和优化，这样就可以在不增加其体积、高度或存在的情况下对其进行维护。

Text description provided by the architects. The main principle regarding the intervention relies on an internal functional remodelling and optimization of the existent building, according to the possibilities initially presented by its original structure and inner spatial layout, which allowed its maintenance without increasing its bulk area, height or presence.

这座建筑可以追溯到70年代，它的建筑特征显然与那个十年联系在一起，这一事实并没有降低它的建筑价值，也没有降低它对大道的城市表现，而这条大道的开放可以追溯到同一时期。

The building dates back to the 70’s, being its architectural character clearly associated with that decade, fact that does not decrease its architectural value and neither its urban performance towards the avenue, whose opening dates back to the same period.

尽管最初是为了同样的办公功能和目的而建造的，但采用的内部组织逐渐过时，面临着当代办公建筑的性能需求所要求的技术、功能和安全要求。

Despite being originally built for the same office functions and purpose, the adopted inner organization became gradually obsolete, facing the technical, functional and safety requirements demanded by the performative needs of a contemporary office’s building.

原来的立面系统被固定在一条技术走廊上的遮阳板所取代和加固，该走廊与每层混凝土板平放，沿着南部-也是最裸露的-立面。

The original façade system was replaced and reinforced by shading panels fixed over a technical corridor levelled with each floor concrete slab, along the southern - and most exposed - facade.

这一升级将使内部区域受益于自然照明和通风，以及办公活动所需的热舒适性，该建筑现在将在最佳的性能条件下容纳这些活动。

This upgrade will allow the inner areas to benefit from natural lighting and ventilation, and the thermal comfort needed by office activities, which the building will now house in optimal performative conditions.
