BLAF的几何设计和环形的建筑能量表现方式在这个房子里得到了强烈的体现。墙体结构外面是自承重的面砖，里面是轻质的木质框架，用生物基干石灰麻填充，没有空腔，是传统空腔墙的替代品。

The geometric design and the circular way of energetically performing building that characterizes BLAF is strongly present in this house. The wall structure with a self-supporting facing brick on the outside, a light timber frame on the inside, and filled with biobased dry lime hemp without a cavity is an alternative to the traditional cavity wall.

带有大量隔热材料的空心墙作为一种建筑系统已不再可行。因此，我们想出了一个替代的混合外壳，使可逆的建筑成为可能。我们首先建造一个外墙，然后在里面建造一个轻质木框架，反之亦然。你也可以将外壳或内壳分解，因为它们各自独立存在。我们根本不计算热桥。那是浪费时间，我们只是不做任何计算。所以里面和外面之间没有连接。为了做到这一点，我们需要一个承重的外墙，你可以把外墙从内部分离出来。

The cavity wall with a lot of insulation is no longer tenable as a building system. As a result, we came up with an alternative hybrid outer shell that makes reversible building possible. We first build an outer wall, and then a light timber frame inside, or vice versa. You can also break down the outer shell or the inner shell because they each stand on their own. We simply don’t calculate thermal bridges. That’s wasted time, we just don’t make any. So there are no connections between the inside and the outside. To do this, we needed a load-bearing outer wall from which you could detach the outer wall from the interior.

该设计涉及一个紧凑和节能的单户住宅。其出发点是：尊重救济和环境。紧凑的体量旨在使从公共领域到后面的景观的视觉关系得到保留。由于紧凑的六边形等边脚印，该体量在景观中独树一帜，未开发的土地尽可能地保留了其浮雕。

The design concerns a compact and energy-efficient single-family home. The starting point: respect for the relief and the environment. A compact volume was aimed so that the visual relationships from the public domain to the landscape behind are preserved. Due to the compact hexagonal, equilateral footprint, the volume stands solitary in the landscape, the undeveloped land retains its relief as much as possible.

侧面倾斜的形状创造了与横向地块边界的较大距离，这限制了对环境的影响，并为邻居提供了隐私。在侧墙，窗户的开口也受到限制，以确保邻居的隐私。为了将体量谨慎地融入景观，并提供足够的住宅方案，房子被推到斜坡上。

The shape with its sloping sides creates a greater distance to the lateral plot boundaries, which limits the impact on the environment and provides privacy to the neighbors. In the side walls, the window openings are also limited to ensure the privacy of the neighbors. In order to integrate the volume discreetly into the landscape and to provide a sufficient residential program, the house is pushed into the slope.

在后面，在封闭的六边形内，我们撤回了受保护的体量，并引入了一个延伸到3层楼的木质幕墙。在幕墙和石壳之间形成的天井在温暖的夏季起到了防晒的作用。幕墙保证了每层楼后面的景观。砖块体量中的开口框住了景观。外墙的混凝土（环形）梁保证了自支撑外墙砖石在风载荷下的稳定性。

At the rear, within the enclosed hexagon, we withdraw the protected volume and introduce a wooden curtain wall that extends over the 3 stories. The patio created between the curtain wall and the stone shell serves as sun protection in the warm summer months. The curtain wall guarantees a view of the landscape behind every floor. The openings in the brick volume frame the landscape. The concrete (ring) beams in the facade guarantee the stability of the self-supporting facade masonry under wind loads.
