飞檐住宅丨Lorenz Bachmann Architect ETH SIA

这个空间被定义为“屋顶中的房间”，由地板与两侧屋面构成唯一的边界。在这里，视线可从四周望向花园与连绵的丘陵景观，让空间既隐蔽而安静，又仿佛无限延展。

The spatial idea is a room in the roof, defined only by horizontal elements: the floor and the two roof surfaces. On all sides, there are views down into the garden and across the hilly landscape. The room is sheltered and, at the same time, seemingly endless.

这是Lara和Marcel的私密休憩空间，他们可以在这里弹奏乐器或安静阅读。地板暗藏储物舱口，可存放他们需要的物品，使空间保持整洁。空间通过楼梯、屋顶天窗及固定玻璃上的圆形开口，与住宅、花园与天空形成多重联系。

It is Lara and Marcel‘s retreat. Here they play their musical instruments or read a book in peace. There are flaps in the floor with sufficient storage space for everything they want to do in the room. The stairs, a roof window and a hole in the fixed glazing connect the room with the house, the garden and the sky.

双坡屋顶向两侧悬挑，创造出两个半室外遮蔽空间：一侧作为入口区，可停放自行车与玩具。另一侧设有厨房露台，连接抬高的地面层与花园，增强室内外的互动。

The gable roof cantilevers on both sides, creating two sheltered outdoor spaces. On one side, there is an entrance area where bicycles and toys can be kept. On the other side, there is a new kitchen terrace that connects the elevated ground floor with the garden.

光伏屋顶系统为整栋建筑提供能源供应，同时抵御天气影响。黑色光伏面板由金属小挂钩固定，确保美观与稳定性。

The photovoltaic in-roof system protects against the weather and supplies the house with energy. The black PV panels are held on all sides by small metal hooks.
