一家名为Ryuichi Ashizawa的日本建筑设计公司设计了一座漂亮的圆形住宅，它被包裹在一个螺旋形的屋顶花园里。这座位于日本偏远岛屿上的家庭住宅用编织的竹子格砌而成，四周覆盖着土墙。从地面上升起的螺旋式花园，为家庭全年可以享受的新鲜蔬菜和草药提供了最佳的生长场地，让家庭和自然之间产生了强烈的联系。

Japanese firm Ryuichi Ashizawa Architects has unveiled a beautiful round home that is wrapped in a spiraling rooftop garden. The family home, which is located on a remote Japanese island, was built out of woven bamboo lattice and clad with earthen walls. To create a strong connection between the home and nature, a spiraling garden that rises from the ground level provides optimal growing conditions for fresh vegetables and herbs that the family can enjoy year-round.





建筑位于偏远的Awaji岛，为一个四口之家而建。其设计目的是利用岛上温和的气候，但同时也从全家人的自然生活方式中汲取了灵感。他们的第一个目标是创造肥沃的种植区，可以满足一家人的全年需求，第二，创造闭合循环的景观系统，使家庭可以自给自足，能够在未来与环境和谐相处。

Located on the remote island of Awaji, the home was built for a family of four. The architects designed it with an eye to withstandi the temperate climate on the island, but they also drew inspiration from the family’s nature-conscious lifestyle. Their first objective was to create a fertile area that could help feed the family year-round. Secondly, the master plan called for creating a closed-cycle landscape to make the home self-sufficient, enabling the family to live in harmony with the environment for years to come.





建筑师们首先用编织的竹格制作了大型圆形框架，然后用Sanwa生土包覆了圆形。在室内的设计中，建筑师使用了一种名为“Tataki ”的技术，用泥土、石灰和水制造出一层坚硬的土质地面。

The architects began by creating a large circular frame out of woven bamboo lattice. They then clad the round form with Sanwa Earth finish. On the interior, they used a technique called Tataki to create a hard-packed earthen floor out of dirt, lime and water.





墙壁也是用泥土制成。土墙和地板的结合为建筑提供了紧密的保温空间。冬天，墙壁和地板吸收热量，夜间释放热量，使居住空间保持温暖。在炎热的夏季，房屋的烟囱效应布局（中央空间和其他房屋之间的高度差异）使得室内得以自然冷却。

The walls were also made out of packed earth. The combination of earthen walls and flooring provides a tight thermal envelope for the home. In winter, the walls and floors absorb heat, which is released at night, keeping the living space warm. In the hot summer months, the home’s stack effect layout (a height difference between the central space and the rest of the home) enables optimal air circulation to cool the interior.







受到家庭成员生态理念生活方式的启发，建筑师们想要将绿色融入到已经足够环保的家居设计中。因此，屋顶被设计为螺旋花园，它的形状适合植物的生长。屋顶花园从地面升起，环绕着住宅，为种植各种植物和蔬菜提供了完美的阳光和湿度。雨水浸入花园的顶部，然后向下流到一系列充满水生植物的池塘之中。

Inspired by the family’s eco-conscious lifestyle, the architects wanted to incorporate greenery into the already eco-friendly home design. Accordingly, the roof was turned into a spiral garden whose shape provides optimal growing conditions. Rising up from the ground level, the rooftop garden wraps around the home, providing a perfect blend of sun exposure and humidity to grow a variety of plants and vegetables. Rainwater soaks the top part of the garden, then flows downwards to a series of retaining ponds filled with aquatic plants.
