架构师提供的文本描述。这所房子坐落在广岛市中心的高楼大厦中，俯瞰着一条街道，那里有许多经过的汽车和电车。为了在这些环境中获得隐私和安宁，我们在房子的街道边放置了一个花园和一个光学玻璃立面。从所有房间都可以看到花园，路过的汽车和有轨电车安静无声的景色给房子里的生活增添了丰富的气息。阳光从东方折射，透过玻璃，创造美丽的光图案。雨水打在水盆的天窗上，显示了入口处的水样。透过花园树木过滤出来的光线在客厅的地板上闪烁着，一层轻薄的金属幕布在风中翩翩起舞。虽然位于市中心的一个城市，房子使居民能够享受变化的灯光和城市情绪，随着时间的推移，并生活在变化的季节意识。

Text description provided by the architects. This house is sited among tall buildings in downtown Hiroshima, overlooking a street with many passing cars and trams. To obtain privacy and tranquility in these surroundings, we placed a garden and optical glass façade on the street side of the house. The garden is visible from all rooms, and the serene soundless scenery of the passing cars and trams imparts richness to life in the house. Sunlight from the east, refracting through the glass, creates beautiful light patterns. Rain striking the water-basin skylight manifests water patterns on the entrance floor. Filtered light through the garden trees flickers on the living room floor, and a super lightweight curtain of sputter-coated metal dances in the wind. Although located downtown in a city, the house enables residents to enjoy the changing light and city moods, as the day passes, and live in awareness of the changing seasons.

使用了大约6 000块纯玻璃块(50毫米x 235毫米x 50毫米)的光学玻璃。纯玻璃砌块以其巨大的单位面积，有效地屏蔽了声音，并创造了一个开放的，清晰的花园，让城市的风景。为了实现这种外观，采用玻璃浇铸法从光学玻璃的原料硼硅酸盐中生产出透明度极高的玻璃。铸造过程非常困难，因为它需要缓慢冷却以消除玻璃内部的残余应力，而且尺寸精度很高。然而，即便如此，玻璃仍保留着微观的表面凹凸不平，但我们积极欢迎这种效果，因为它会在内部空间产生意想不到的光学错觉。

Optical Glass Façade A façade of some 6,000 pure-glass blocks (50mm x 235mm x 50mm) was employed. The pure-glass blocks, with their large mass-per-unit area, effectively shut out sound and enable the creation of an open, clearly articulated garden that admits the city scenery. To realize such a façade, glass casting was employed to produce glass of extremely high transparency from borosilicate, the raw material for optical glass. The casting process was exceedingly difficult, for it required both slow cooling to remove residual stress from within the glass, and high dimensional accuracy. Even then, however, the glass retained micro-level surface asperities, but we actively welcomed this effect, for it would produce unexpected optical illusions in the interior space.

瀑布如此之大，是8.6m×8.6米的正面，如果用50毫米深的玻璃砌块建造，它就无法独立站立。因此，我们用孔洞刺穿玻璃块，并将它们固定在悬挂在立面上方梁上的75个不锈钢螺栓上。这样的结构将容易受到横向应力的影响，因此，随着玻璃块，我们也在10厘米间隔的不锈钢扁钢条(40毫米x4毫米)。扁棒位于50 mm厚的玻璃块内，使其隐形，从而实现了玻璃块之间均匀的6mm密封连接。结果-从花园或街道上看到一个透明的立面。外观就像一条瀑布，向下流淌，散射光线，充满清新的空气。

Waterfall So large was the 8.6m x 8.6m façade, it could not stand independently if constructed by laying rows of glass blocks a mere 50mm deep. We therefore punctured the glass blocks with holes and strung them on 75 stainless steel bolts suspended from the beam above the façade. Such a structure would be vulnerable to lateral stress, however, so along with the glass blocks, we also strung on stainless steel flat bars (40mm x 4mm) at 10 centimeter intervals. The flat bar is seated within the 50mm-thick glass block to render it invisible, and thus a uniform 6mm sealing joint between the glass blocks was achieved. The result　—a transparent façade when seen from either the garden or the street. The façade appears like a waterfall flowing downward, scattering light and filling the air with freshness.

说明玻璃砌块的外墙重约13吨。支撑梁，如果是用混凝土建造的，因此将是大尺寸的。采用钢框架钢筋混凝土，对钢梁进行了预张，并给出了一条向上弯曲的曲线.然后，在给它的外立面的负荷，我们在梁周围浇筑混凝土，这样，它的大小最小化。

Captions The glass block façade weighs around 13 tons. The supporting beam, if constructed of concrete, would therefore be of massive size. Employing steel frame reinforced concrete, we pre-tensioned the steel beam and gave it an upward camber. Then, after giving it the load of the façade, we cast concrete around the beam and, in this way, minimized its size.
