这是对布拉格一处家庭住宅的改造，该住宅在20世纪30年代作为最初的休闲建筑进行了几次翻修，作为永久性住宅，此后再也没有进行修整，考虑到安全问题，业主向我们提出了翻修建筑的邀请。

It is the construction modification of a family house in Prague, which was completed and reconstructed several times as an originally recreational building from the 1930s for permanent residence. Considering these interventions, its stability was no longer sufficient.

我们最终的方案，是给建筑加上一件钢铁的“束腰”用来加固建筑；原来的屋顶只有15厘米厚，考虑到实际使用问题我们最终决定拆除整个屋顶，这不仅可以更有效地解决防风雨问题，还可以调整地上二层的空间布局，因此我们在二楼扩建了一个新房间，位于前露台上。

The fundamental decision was thus to complement and in general stiffen the construction with a steel corset. Another problem was the original mansard roof, which had a thickness of only 15 cm. The removal of the entire roof, which we decided for in the end, allowed not only a more effective resolution of the problem of the weatherproofing, but also adaptation of the layout on the second floor above ground so that it met the demands of the investor. The second floor is also expanded by a new room in the space of the former terrace.

铁“束腰”不仅是一个观赏元素，它还打算作为攀爬植物的棚架，并在建筑方面巩固整个建筑。

The steel corset is not only a technical element; it is intended also as a trellis for climbing plants, and consolidates the entire building in terms of the architecture.

整个“束腰”由相同的钢棱柱组成，由1280毫米的L型钢焊接而成，能够理想地保持建筑物的保留部分的现有入口。轻质混凝土砌块砌成的砖石结构，加固了二楼的承重钢部分，并有助于承载新的屋顶钢筋混凝土板，该板将作为可步行的露台，是屋顶花园的一部分。

The whole corset is comprised of the same steel prisms welded from L profiles in a module of 1280 mm. This module made it possible to ideally preserve the existing openings of the retained part of the building. The masonry construction of the second floor from lightweight concrete blocks complements the bearing steel part and helps carry the new roof reinforced concrete slab, which will serve as a walkable terrace with a garden modification.

由一个服务楼梯可以直接从花园直接进入屋顶，在楼顶上，建筑物侧面的设计以及二楼内部的空间将清晰可见。同时它也是由支撑钢结构组成，所有材料都以其自然形式存在。

Access to the roof directly from the garden is made possible by a service staircase, which is designed from the side of the building within the steel construction. The interior of the second floor leaves the concrete blocks and concrete ceiling visible. Along with the supporting steel structure, all materials are therefore admitted in their natural form.
