架构师提供的文本描述。居住别墅Drei Birken位于白云石住宅区尽头的山坡上。这座别墅建于1960年，于80年代翻修，最初由一套简单而低体积的公寓和四套度假公寓组成。新的扩建增加了六个假日公寓以及功能和公共空间。从最封闭的北立面到完全玻璃化的南立面，面朝太阳和白云石的全景通过V形表面打开。

Text description provided by the architects. Residence Villa Drei Birken is located on a hillside at the end of a residential area in the Dolomites. The Villa, built in 1960 and renovated in the 80’s, originally consisted of a simple and low volume with owner’s apartment and four holiday flats. The new extension adds six holiday apartments as well as functional and common spaces. The facade opens through a V-shaped surface from the mostly closed North facade to the completely glazed South facade, facing the sun and the panoramic view of the Dolomites.

虽然它是连接在较低层与现有别墅，新的建筑是设计作为一个独立的建筑。完美地融入山坡，由于其可达的广泛的绿色屋顶与综合露台，新的体积占据了全部宽度的情节。它是轻微旋转，以引导南面的太阳和全景。较低层的接缝将新建筑与现有建筑连接起来，作为公共餐厅。由于内部的功能分布，东面和北立面相对封闭；此外，北面的设计是为了显示新建筑和现有建筑之间的明显分离。车位也在街边，六间宽敞的假日公寓直通阳光，可以俯瞰白云石的全景。

Although it is connected in the lower level to the existing villa, the new construction is designed to appear as a free-standing building. Perfectly integrated into the hillside thanks to its accessible extensive green roof with integrated terrace, the new volume occupies the full width the plot. It is slightly rotated in order to direct the South facade to the sun and the panoramic view. The joint in the lower level connects the new with the existing building and serves as common dining room. The East and North façades are relatively closed because of the interior’s functional distribution; furthermore, the North side is designed to show the clear separation between the new and the existing building. The volume is accessible from the street side, where also the car parking is located.  The six spacious holiday apartments are directed to the sun, with panoramic view of the Dolomites.

新建筑的围护结构仅由三种主要材料组成：墙壁上覆盖着各种宽度的水平预氧化铜板，而北凹区和阳台则用落叶松木条板抵消。此外，南面主要采用全高玻璃。对落叶松木材用硫酸铁染色灰化液进行处理，以使北方的服务量多样化。铜和落叶松木材暴露在太阳、雨和雪的大气影响下的自然颜色变化中；这一现象除了重复别墅的木制色彩代码外，随着时间的推移，进一步增加了建筑物与其背景的融合。

Material The new building’s envelope is made of only three main materials: it’s walls are clad with horizontal preoxidized copper sheets of various width while the Northern recessed area and the balconies are offset with larch wood strip boards. In addition, full-height glazing is predominantly employed on the Southern façade. The larch wood is treated with a pigmented graying solution of iron sulphate, in order to diversify the North service volume. Copper and larch wood are exposed to a natural change of colour caused by the atmospheric influence of sun, rain and snow; this phenomena, in addition to the repetition of the wooden colour code of the Villa, further increases the integration of the building into its context over time.

内部是清晰，简单和功能。它包含用桦木胶合板定制的家具，被涂油或深色，与铜类似。

The interior is clear, simple and functional. It contains custom furniture in birch plywood, which is oiled or dark stained so as to be similar to the copper.

特别注意改善建筑物的能源性能，如三重玻璃门窗、控制通风系统、与木球集中供热装置相连的供暖系统和用木纤维隔音等。

Particular attention was paid to improving the energy performance of the building, such as doors and windows with triple glass, controlled ventilation system, heating system connected to a wooden pellets district heating plant and heat-sound insulation with wooden fiber.
