We sanitised all the wooden columns and beams, adding hidden steel reinforcements where necessary, levelled the ground introducing floor-heating, improved the thermal insulation of the roofs using high-density foam panels (between the rafters in the lower volumes and above the wooden panels in the central space) and added a new waterproof layer. The high-walls of the central space, deteriorated by years of rainwater leaks, were completely rebuilt with a new stripe of double-glazed windows.
Once we obtained a clean and sound envelope we proceeded with the interior construction, which mainly consisted of a new self-standing metal mezzanine, glazed partitions on the South side and some built-in steel furniture.
我们对建筑表皮的干预是修复性的,并必须严格遵守原先的轮廓。从木材的截面可以清晰分辨出其建造的时期——圆木属于原有结构,而方木则是工厂时期的加建结构,我们最大程度的保留了所有的木结构,并在个别局部采用不同的金属构件加固。此外,在屋面及地面都增加防水和保温层,并安装地暖设施,使用导热性较好的素混凝土地面。原先三个屋顶体量之间所形成的天沟导致其相邻墙面因长年的潮湿完全腐朽,因而亟待重建,并将原有的带状高窗替换为热工性能更好的双层中空玻璃。
室内空间的干预则主要包括增加一个具有独立结构的钢结构夹层,南房北面的玻璃隔断和一系列的嵌入式家具。
