该项目是被Bahia Blanca市的一座新学术遗产建筑遗弃的大型空间，经翻新而落成CABB礼堂，它最近被学院收购，自二十世纪初以来一直作为“新省”总部。在砌体框架内引入了一种新型木板框架，是预先存在的高度的两倍，形成中间有层隔板的双腔。所创建的新角柱与整体结构成比例地进行调整，从而设法校正原始墙面的尺寸不规则性。夹层楼设有独立通道，可从阳台俯瞰主厅。

Text description provided by the architects. The project of the Auditorium of the CABB resulted from a request to renovate a large disused space on the first floor of a neo-academic heritage building in the city of Bahia Blanca. It had been recently acquired by the College and had functioned as the headquarters of the newspaper ‘The New Province’ since the beginning of the twentieth century. A new wooden-paneled frame was introduced inside the masonry frame, twice the pre-existing height, to form a double cavity. The new prism created was adjusted in proportion to the overall structure, thereby managing to correct the dimensional irregularities of the original wall face. A mezzanine floor with independent access overlooks the main hall from the balcony.

平台 - 唯一的实体元素 - 组织了项目的不同领域。礼堂的一面侧墙靠在主立面上；三扇高窗享有整个城市广场的景致。在另一侧，与这三个窗口线性重合，三个入口通过大理石楼梯可以通向已存在的门厅。该区也被认为具有遗产价值的。

The stage - the only solid element - organized the distinct areas of the project. One of the lateral walls of the auditorium leans against the main facade; three high windows provide views across the foundational city square. On the opposite side, and linearly coinciding with these three windows, three access ways were opened up towards the pre-existing foyer reached by marble floor stairs and old iron balusters with cedar wood banisters. This area is also recognized as having heritage value.

平台采用'Guatambu'木材制成，形成一个固体（可从更衣室进入双层通道）和两个移动平台。它配备了可伸缩的视听投影仪屏幕和机械幕布。在平台后面，组织了配套设施和服务室。位于夹层楼的技术室设有完善的控制台系统，照明和投影设备。礼堂可容纳177人：访问层有144个座（包括残疾人座位），夹层楼有33个座位。

The stage, made with ‘Guatambú’ wood, forms a fixed section (with double access from the dressing rooms) and two mobile platforms. It is equipped with a retractable audiovisual projector screen and a mechanical curtain. Behind the stage, support and service rooms have been organized. The technical room, situated on the mezzanine, houses a sound console system, lighting and projection equipment. The auditorium has a seating capacity of up 177 people: 144 seats (including disabled seating) on the access level and 33 on the mezzanine level.

所使用的模型 - Z2 - 安装在双腔中，通过添加两个移动平台，可以完全灵活地创建特定配置。为了达到声音吸收和反射的最佳声学标准，墙体覆盖有镶板。微孔板安装在较低的层面，中央单元中有声扩散器“Qrd”。还设计了庇护屋檐以最小化任何环境噪声。

The model used – Z2 straight – were fitted in mobile tandem pairs and, by adding two mobile stage platforms, allows complete flexibility in creating specific configurations. In order to achieve optimum acoustic standards of sound absorption and reflection, the walls were covered with sheets of paneled veneer. Micro-bored sheets were installed at the lower level with an acoustic diffuser ‘Qrd’ in the central units. Acoustic cloud canopies were also added to minimize any ambient noise.

新建空间由旧建筑的织物支撑，创造了双腔墙体，现有的木地板和实木门经过了镶板和改造。现代建筑与原始学院之间实现了和谐的平衡。最终的结果是令人愉悦地融合了上世纪初使用的原始外观和建筑方法，以及达到当前建筑标准所需的新技术和这个空间所需的木板。

The new space was supported within the fabric of the old building by creating double cavity walls, and the existing wooden floor blocks and solid wooden doors paneled and adapted. A harmonious balance was achieved between modern architecture and the original academy. The end result was a pleasing blend of the original appearance and building methods used at the beginning of the last century, and new technologies needed to reach the current building standards and wooden-paneled required for this space.
