架构师提供的文本描述。这座房子位于越南中部的一座城市内，周围是美丽的海洋和山脉。客户想要一幢有大花园的大房子。应这一要求，一个屋顶被设计成一个悬挂花园，在上面种植无数的树木和植物。然而，当地的建筑法规要求几乎50%的屋顶被灰色或橙色倾斜覆盖并倾斜。为了遵守这一规则，但最大限度地扩大顶部的绿色面积，屋顶被划分为平行的带绿色屋顶和平铺屋顶的交替顺序。

Text description provided by the architects. The house is located in Nha Trang, a city in central Vietnam surrounded by the beautiful ocean and mountains. The client wanted a large house with a large garden. Answering to this request, a single roof is designed as a hanging garden to plant numerous trees and plants on it. The local building code, however, requires almost 50% of the roof area to be covered by gray or orange-color tilings and to be sloped. To obey this rule but maximize the green area atop, the roof is divided into parallel bands of greened roofs and tiled roofs in an alternating sequence.

房子的内部空间是由这个平行带系统构成的。瓷砖屋檐下有起居室、餐厅和床位，而浴室、储藏室和循环空间等服务空间则位于绿化屋顶下，屋顶高度由于树顶土层较深而受到限制。在波段系统中设计了一个空隙和三个露台，以加强自然照明和通风。

The interior spaces of the house are structured by this system of parallel bands. Under the tiled roof are the living, dining and bed rooms, while service spaces, such as bathrooms, storages and circulation spaces, are located under the greened roof, where the ceiling height are limited because of the deep soil layers for trees atop. A void and three patios are designed within the system of bands to enhance natural lighting and ventilation.

这座房子是名为“树屋”的系列住宅项目的最新变体之一。大的单一屋顶与私人住宅的规模相去甚远。它更像是向邻居开放的基础设施或袖珍公园。轻轻倾斜，这屋顶景观是视觉连接到周围的山脉。在绿树成荫的环境下，居民们可以欣赏风景，在绿色植物中度过他们的一生。

The house is one of the latest variations of the serial house project called ‘house for trees’. The large single roof is departing from the scale of private house. It is more like an infrastructure or a pocket park open to the neighbors. Gently sloped, this roof-landscape is visually connected to the surrounded mountains. In the shadow of trees, the residents can enjoy the views and spend their life with full of greenery.
