巴塞罗那 CMT 总部大楼，旧厂房新生，创新室内设计

Like the INTERFACE building, the building for the Telecommunications Market Commission (CMT) is situated in the 22@ district. In this case, the building forms part of a complex, 22@ Business Park, developed by Grupo Castellví and containing a large business complex of over 41,000 m2 of offices and hotels, delimited by four streets: Bolivia, Ciutat de Granada, Sancho d’Àvila and Badajoz. Also set in this sector is one of the factories of the old Can Tiana textile mill, built in 1906 to a project by Guiteras and listed in the Special Protection Plan for the Industrial Heritage of Poblenou.

The CMT building stands on a long, narrow site that presents its main façade to Carrer Bolivia and is delimited to either side by a passage. One of the old Can Tiana factory buildings stands at the centre of the site, and the project sets out to recover and incorporate it into the CMT’s functional programme. The main volume comprises three basement floors for car parking and eleven floors above grade with offices and services. The ground floor, providing the function of access and entrance, connects with the old mill building, the original structure of which is conserved as an auditorium with capacity for 330 persons, a large meeting room and services for CMT employees. The roof of the mill was adapted for use and connects with the first floor.

The main volume, containing the offices, is organized around a central nucleus of entrances and services, and the workstations are laid out around it, making full use of the spatial freedom enjoyed by a building that opens out on all four sides. This allowed us to explore a volumetric formalization that sets the building apart from its surroundings, highlighting its lengthwise asymmetry and increasing its height in relation to the axis of the street.

This formal freedom produces a singular form, faceting the faces of the building and moulding it as a unique, recognisable piece that finds its reason for being in an innovative relation between exterior and interior. The variation and superposition of exterior spaces and workspaces serve to direct the volume towards the old factory and establish a subtle, utilitarian relation. The distant presence of the sea and a south-facing orientation determine the correct position of the terraces.

The decision to bring a unitary treatment to the building’s outer appearance led us to protect its façade using a horizontal slat system throughout its volume that continues over the old factory, connecting the two. The slats serve to cover the upper terraces and installations, and form an awning at the ground floor entrance.

CMT位于22@区，与四个街区关联，是一个面积超过4万1千平方米的综合性办公及酒店建筑。这一领域也是工业遗产保护区，有着1906建立的Tiana纺织厂。

CMT在一个狭长的用地之中，老的工业厂位于场地中间。建筑包含地下3层停车场以及11层的办公。底层与原来的旧工厂联系，旧工厂用作330人的大会议室以及员工服务礼堂，工厂屋顶也与建筑相联系。建筑的核心筒在中央，办公区域围绕四周，面向外面的美景。建筑的外型是不规则的，形成奇异的体量，这不光影响着建筑的内部空间，也使得建筑成为一个标示性的建筑。同时与老厂房形成微妙的关联。建筑师在新建筑上采用与老厂房语言一致的水平板式表皮系统，将两个建筑统一起来。板式表皮系统能为每层遮阳，同时也形成了地面入口的雨棚。
