Appreciation towards BAST for providing the following description:

这座位于法国南部城市图卢兹的建筑内部空间得到了完全重整与合并。长长的走廊沿着立面延伸，串联起一个个房间，阳光从屋顶上小小的天窗倾洒而下，为卧室带来明亮的天光。在建筑的后院，严格遵循城镇规划法则而建的一层小体量空间内容纳着厨房与休息室。深黑色的金属框架结构素雅而沉稳，完全融入了环境之中，同时简单的结构也保证了这个增建体量可以随需要改变而随时拆除或重建。连续的玻璃幕墙让建筑古老的红砖立面一览无遗。微微的倾角不仅让新建体量能够常年沐浴在阳光的照射下，同时也在两个体量间创造出一个既私密，又开敞的开放空间。

A Toulouse house is emptied to incorporate rooms. A corridor, along the facade, distributes these rooms on the second light. Rooms with floor and enjoying a skylight allow direct light in each sleeping area. An extension in one volume in ground floor (kitchen / lounge) is built on the buildable portion defined by the town planning’s regulation. From an aesthetic point of view, its metal frame was designed in harmony with the land. Moreover, it is easy to mount and dismount in a relatively short time. In the face of the house, transparent facades stages the ultimate brick façade of the original house. In addition to its orientation plunging the house into a sun bath, its location between the two buildings creates a yard that becomes a place of outdoor privacy.

4块巨大的混凝土板在不干扰现状围墙的情况下，界定出新建筑的空间。在此基础上，4个定制的金属框架搭建出整个金属结构的雏形。建筑师按照具体需要，在倾斜的屋顶平面、平整的地板平面与金属框架的交界处设计了四种节点，在保证结构稳定的基础上导流雨水。

The foundations are made by 4 footings of concrete, without coming close to existing neighboring walls. On these 4 foundations, 4 frames custom-made steel pipes constitute the primary framework of the metal frame. Fixed within these frameworks, 4 types of profiles are given the bottom floor and the top floor. These sections all have a different design depending on their position in the section : top or bottom of the roof slope, in bank of floor top or bottom floor. The profile makes bank high floor down roof slope receives a folded sheet steel making gutter rainwater.

建筑的地面层中，保温绝缘材料被放置在厚厚的预制混凝土梁之上，而其上的压缩层经过了打磨和清漆修饰，稳固而防水。而顺着屋顶微微倾斜的屋顶层则由预制夹芯板组成，从外至内依次为瓦面、防水层、木板与厚厚的保温层，在最内部，洁白的石膏板干净整洁。

The bottom floor is made of prefabricated concrete beams and insulation interjoists that arise in the thick bottom edge profiles floor. Above is poured a compression layer, the surface is sanded and varnished to give a finished coating, waterproof and sturdy.

The top floor, following the roof slope, is made of prefabricated sandwich panels comprising a wood layer which receives the rain barrier under the cover, an insulating thickness and a gypsum board coating which plays the role ceiling.

▽ 室内空间，interior space

通透的玻璃幕墙与一前一后两扇拉门组成了建筑的立面。幕墙或外挂于金属结构之上，或内嵌于轨道之中。木制的拉门在黑色的金属框架结构中显得格外活跃，顺着铝制的轨道缓缓滑动，让室内外空间完全融为一体。

考虑到法国南部夏天炎热的夏天，建筑师在南侧立面上安装了滑轨和窗帘，在夏季为建筑隔绝炙热的炙热阳光。

The 2 facades receive fixed glass fixed on steel angles and two twins sliding. Fixed glass are glued externally on the profiled sides or angles fixed directly on the banks high and low. Sliding are wooden and percussion to be on the same plane. They slide on their whole length on an aluminum rail fixed on the low side.

In southern facade, a rail is welded to the top of the high bank to slide 2 micro perforated canvas curtains to protect the extension of the summer sun.

而这一切都是建立在简简单单的四个金属框架结构之上。

Finally, the primary structure consists only of 4 frames in steel tubes, which define the volume in which the entire building is built.
