架构师提供的文本描述。这座房子位于维托沙山郊区索非亚附近的一个低层住宅区。该项目被初步定义为一座具有合理空间、极高能效和室内气候舒适性的现代住宅，完全由一个楼宇自动化系统控制。

Text description provided by the architects. The house is located in a low-rise residential area near Sofia, in the outskirts of Mountain Vitosha. The project was preliminary defined as a contemporary house with rational spaces, very high energy efficiency and indoor climate comfort, fully controlled by a building automation system.

设计的主要挑战是保存现存的两棵老橡树，并将它们整合在房子的空间中。树木创造了一种自然的微气候，并在构图中起到了活生生的作用。设计理念的重点是定义它们周围的空间。一方面，房子要向树冠和院子敞开，另一方面要强调一定的外壳或信封-明快而又轻盈的…。就像一张纸。从而出现了以“纸的主题”为主导的概念，具有折叠的内在属性。

Main challenge of the design was the preservation of the two existing old oaks and their integration in the spaces of the house. The trees create a natural micro-climate and function as a living element in the composition. The accent in the design concept was defining the space around them. On one hand the house has to be wide-open towards the tree crowns and the yard and on the other was the desire to emphasize on a certain shell or an envelope – explicit and yet very light and airy…, like a paper. Thus appeared the leading concept - taking the „paper theme” with the inherent property of folding.

决定建筑物形状的因素是这两棵树，其中之一是它的空间和功能焦点。地面上的起居区是一个单一的空间U形，由厨房、餐厅和客厅组成，全玻璃化，面向庭院开放。

The factors that determine the shape of the building are the two trees, and one of them is its spatial and functional focus. The living zone at the ground level is a single space U-shape, consisting of kitchen, dining room and living room, fully glazed and open towards the yard.

釉面砖的每一半都是一个滑动的元素，所以当所有的元素在夏天开放时，生活区就会变成有盖的露台朝向院子。在这一层，也有两辆车的正门和车库。楼上有两间卧室，主卧室和一间小办公室。这第二层是完全玻璃和开放的树木，因此，它的感觉就像散步穿过一个有盖的木制甲板上的皇冠。

Each half of the glazed tiles is a sliding element, so that when all elements are open in summer, the living area turns into covered terrace towards the yard. At this level are placed also the main entrance and a garage for two cars. At the upper level are situated two bedrooms, master bedroom and a small office. This second level is thoroughly glazed and open towards the trees so that being on it feels like a walk through the crowns on a covered wooden deck.

保存这两棵现存的树木对建筑的热平衡起着重要的作用，因为它的体积很大。橡树作为一种自然的保护措施，防止夏季过热，有助于地热冷却热泵系统，该系统为地面提供过量的热量，在冬季被抽回来。当树叶在冬季脱落时，低冬季的太阳会穿透生活空间深处，使楼板中的热质量充满能量。

Preserving the two existing trees plays a significant role for the thermal balance of the building with so much glazing of the volume. The oaks serve as a natural protection against overheating in summer, contributing to the geothermal cooling heat-pump system which charges the ground with excessive heat, pumped back during the winter season. When the leafs are fallen off in winter the low winter sun penetrates deep in the living spaces, charging the thermal mass in the floor slabs.

该房子非常节能，它有一个地热热泵(深井)低温地板加热/冷却，三层充气玻璃(UW=1W/M2K)，20-16厘米厚的玻璃-羊毛保温的不透明建筑。也有控制通风系统，具有较高的热回收水平.

The house is very energy efficient, it has low-temperature floor heating/cooling with a geothermal heat pump (deep boreholes), triple gas-filled glazing (Uw=1W/m2K), 20-16cm thick glass-wool thermal insulation on the opaque construction. There is also controlled ventilation system with high level of heat-recovery.
