架构师提供的文本描述。这项工程是对两层木屋的翻修(1980年建造，1989年作为二楼扩建的一部分)。新主人希望能享受到一间拥有现代家具和灯光的房间，这些家具和照明都是精心收集起来的，方法是用旧房子买下这个地方，并翻修一个主空间。现有的房子在一楼被规划成一个典型的LDK，从二楼的南角和东南角被设计成一扇海湾窗户，好让人看到它。原业主在二楼有隔间窗的东侧延伸部分与其他二楼之间存在约600 mm的高度差异，在平面、结构上也存在差异。

Text description provided by the architects. This work is renovation for two-floor wooden house (built in 1980, part of second floor extension in 1989). New owner had hoped to enjoy a room with modern furniture and lighting that had been diligently gathered, by purchasing this site with old house and renovating a main space. Existing house had been planed a typical LDK in first floor, and a bay window for good view from south and southeast corner that had been aware of it in the second floor. There is approximately 600mm high difference between east extension part that has the bay windows on the second floor by original owner and other second floor, its discrepancy has occurred also in a plan, structure as well.

根据这些情况，我决定规划“一个房间的LDK”，跳过整个二楼的楼层。然后采用屋架作为吊顶，以保证天花板的高度，在屋面上放置泡沫保温材料，但作为维修工作是不可避免的。我想这不是为了展示一个横截面的家，当我们完成天花板时，我们需要比它更好的表达。

I decided to plan “one room LDK” with skipping floor of all second floor based on these conditions. Then roof truss was shown by taking the ceiling in order to secure the ceiling height, put foam insulation on the roof, but it was inevitable as repair work. I thought it is not to show a cross-section home that was born when we finished up the ceiling , we need better expression than it.

因此，从二楼的截面形状及其曲率来看，拱顶的最终形状与摆线曲面的顶棚相似。我认为拱顶的天花板是从低层开始的，2英尺1，500毫米的墙，所以它是一种可以感觉到更强烈的拱顶空间。“跳马”的房间就像跳地板一样诞生了。

So in the wake of the arch was in facade, final ceiling form was similar to the ceiling vault of cycloid curved surface from the cross-sectional shape of the second floor and its curvature. I think that vault ceiling start from low level, 2FL +1,500 mm of the wall, so it was a form of vault space can feel more strongly. Room of "skip-vault" had born in the same way as skipping floor.
