Central Market of Cadiz,Rehabilitation and Enlargement By Carlos de Riaño Lozano

当你走到建筑屋顶之上，看到各个立面四扇华丽的大门之后，从建筑到内部，所有的疑惑都被消除了，这些从街道上是很难察觉到的。

 After going up to the roof, all doubts were cleared upon seeing four splendid doors, one in each facade, imperceptible from the street level, in a building overturned to the interior.

这两栋完全不同的建筑：其中一栋竣工于1838年的新古典主义建筑，由Juan Daura主持设计。另一栋营房造型的建筑由Juan Talavera负责，于1929年竣工。

There were two clearly differentiated architectures: a neoclassic one, finished in 1838, under the responsibility of Juan Daura. And another one barracks-like, signed by Juan Talavera and dated in 1929.

由于第二栋建筑遮挡了前一栋建筑和广场纪念碑，而建筑本身又缺乏通风和自然光照，拆除工作锁定在对建筑外缘的保留和内部的重建，并同时解决能源消耗问题。

The second one drowns the first and prevents the vision of the monument. At this point the decision was clear: to keep the perimeter and to demolish the centre. We must emphasize the lack of ventilation of the nave and the absence of natural light that permanently forces the use of artificial light, with the consequent calorific load for people and goods.

修建工作有一系列必要前提。新的建筑需要透气且不能被遮挡视线。这个可以满足开放性，渗透性和透明的新建部分将同被拆除的建筑一样有很小的空间体量。一个明亮通风的建筑内部给予空间，列柱，拱廊以透视的感觉。

There were a series of forced premises. The old building would have to breathe and to be seen in its totality. The new one, opened, permeable and transparent, would count on a similar capacity as the demolished one. A luminous and ventilated interior would allow a long perspective and the perception of the colonnade and surrounding arches of access. 

雨棚之上的结构由透明倾斜45度角的玻璃木板装饰，每条玻璃板尺寸为180*30cm，由管状圆滑金属固定。其透明玻璃的设计满足自然采光和通风，同时映射其身后的历史建筑细部。

The structure on top of the awning is covered with slats of extra clear glass with shading serigraphy, at a fixed angle of 45º. Each unit measures approximately 180 by 30 cm and it is mounted on a tubular metallic stainless steel substructure of AISI-316 quality. We chose a glass solution for its transparency, which offers a view of the historical building, while it gives lightness to the new one and facilitates a permanent ventilation of the interior.

一系列白色轻薄的混凝土立面作为3.30m的房顶支撑，并将摊位有序分割。尺寸为60*30，类型相同的混凝土立柱，被用于支撑130*30m的顶上横梁。

A series of thin white concrete screens separate the stands and support the 3,30 m. roof projection. Beyond the roof projection, the screens have 60 by 30 cm pillars of the same type of concrete, which support 130 by 30 m girders that support the roof slab.

建筑改建方案由公共事业部，住建部，建筑和城市规划部门发起，在十个建筑师项目竞争中产生。新建筑契合了其所有者Benjumeda和Daura的开放市场的想法，街道与市场相交融在加迪斯温暖的气候中。新的市场连接解放广场，临Alcalá Galiano大街和Libertad 大街，呈四边形。其四边长度分别为106,75 m, 56,00 m, 106,73 m, and 55,78 m，总面积6,602.93 m2。原来的建筑在经历严格的修复程序后，其内部结构和石材建筑部分被完全恢复。

The assignment emerged from a limited competition amongst ten architects, after a previous merit selection stage. It was called by the Ministry of Public Works, Department of Housing, Architecture and City Planning, Division of Architecture.It maintains the idea of an open market, as conceived by its authors Benjumeda and Daura. The street enters the market and the market goes out to the street, thanks to the warm Cádiz weather.The market covers a surface bordered by Libertad square, Alcalá Galiano street and Libertad street, significantly rectangular. Its sides measure 106,75 m, 56,00 m, 106,73 m, and 55,78 m, and the total surface is 6,602.93 m2.The original building has passed through a rigorous process of restoration and the hidden structures and stone elements have been recovered.
