架构师提供的文本描述。诺托河就在房子附近。在那里，人们可以在夏天欣赏萤火虫的光芒，在秋天欣赏美丽的彩叶，此外，我们有时还会看到鹿在河边游玩。我们建议我们的客户可以通过在河边设计一个开放的花园来享受大自然赐予的丰富礼物。

Text description provided by the architects. Noto River runs nearby the house. At there people can enjoy watching gleam of fireflies in summer, and beautiful color leaves in autumn, besides we sometimes see deer visits to the riverside. We suggested the house where our client can enjoy the abundant gift from nature by designing an open garden nearby the riverside.

我们设计了楼梯形的屋顶，一直延伸到河边.在屋顶上，我们的客户可以欣赏萤火虫，鹿和彩色树叶。从屋顶上我们可以欣赏到山的景色。瓦库萨山和山。伊科马。这样人们就可以观看一些传统的壮观的山岳盛事，比如夏天的“大蒙吉”篝火和元旦的“山烧”(Wakakusa-yama Yamayaki)。

We designed stairs-shaped roof that is down to the riverside. On the roof our client can enjoy watching the fireflies, deer and color leaves. From the roof we can enjoy scenery of Mt. Wakakusa and Mt. Ikoma. So that people can watch some traditional spectacular events of the mountains such as “Daimonjiyaki” bonfire in summer and “Wakakusa-yama Yamayaki” (mountain burning) in new year’s days.

 Floor Plan

楼梯形屋顶作为屋内的屋檐。它有很多打开的窗户。从北面花园反射出来的阳光透过洞口保持稳定的亮度。我们用内置的格栅铺设防震织物墙.墙从南面的扇光玻璃窗反射阳光到天花板的内置格栅。结果，墙在光线和阴影之间提供了进入室内的瞬变。

The stairs-shaped roof works as eaves for inside of the house. It has a lot of opening windows. Stable brightness is kept through the openings by sunshine that is reflected from the north side garden. We put earthquake-proof fabric wall with built-in gratings. The wall reflects sunshine from fanlight glass windows in south upside to the built-in gratings of ceiling. As the result the wall provide transience between light and shadow into inside the room.

楼梯形的屋顶也有内置的格栅。我们使用防震织物，尽可能地挡住人们的视线。这样人们才能看到廊道似的门廊，北方的花园，诺托河和开阔的天空。我们的设计在有限的空间内，通过开放式和平直的结构，营造了一种开阔的氛围。

The stairs-shaped roof has built-in gratings, too. We used earthquake proof fabric which blocks people’s view as minimum as possible. So that people can see verandah-like porch, northern garden, Noto River and open sky in the end. Our design gives an open atmosphere in the limited space by the open and flat structure.

Wherever people sit down (at stairs-shaped roof or inside the room), people can feel open atmosphere, so client will invite many visitors to the house.

楼梯型屋顶还提供了自然能的舒适通风系统.

The stair-shaped roof also contributes comfortable ventilation system with natural energy.

楼梯顶棚朝北。在夏天，清凉的微风从河面吹来，像门廊一样，从门廊开着的窗户流入屋内。冬天，阳光透过南面的扇光玻璃窗，弥漫在房子的每一个角落。因此，我们的设计实现了充分舒适的室内环境利用自然能源在每一个季节。

The stairs-roof is down for north. In summer cool and fresh breeze from surface of the river flows into the house through the opening windows at verandah like porch. In winter sunshine spreads into all over the house through the fanlight glass windows in south upside. So, our design realizes fully comfortable indoor environment by natural energy at every season.
