Caramel在维也纳市郊的CJ5住宅项目设计中巧妙地应对了高城市密度带来的挑战。

维也纳市郊的建筑普遍高度为4.5m~7.5m，可以建造两层高的独立住房或联排房。一方面，住宅附带的花园和露台提供了高品质的生活质量；另一方面，0.2~0.4 的低容积率对空间提出了很高的要求。

因此出于基础设施建设和节约空间的考虑，很有必要将该区域的建筑容积率提高到0.4 ~ 0.8，甚至是0.8 ~ 1.2，目前只能通过建设高密度的多层公寓楼达到这一点。

在CJ5项目中，Caramel Architects设计了宽敞的花园和露台，保证了独立式住宅的高品质生活，同时建筑容积率达到1.0。因此，与由若干单元构成的多层公寓楼比较起来，该项目的密度更大，但与外部空间没有直接联系，是一所全封闭式的住宅。

In its design for the housing project CJ5, Caramel tackles the question of sustainable urban density on the outskirts of Vienna.

Building heights of between 4.5 and 7.5 metres are permitted for the type of building prevailing there, which allows for the construction of estates of two-storey detached or terraced houses. On the one hand, they display a high individual quality of life, with adjacent gardens and terraces on the living level, but on the other hand they result in very high space requirements due to their low floor area ratio FAR (= usable living area / property area) of 0.2 to 0.4.

From an infrastructural and space-saving perspective, it would be worth striving not only for a denser flat construction style (FAR 0.4-0.8) for these areas, but also a FAR of 0.8 to1.2, which at present is only achieved by means of densely built multi-storey apartment blocks.

With the pilot housing project CJ5, Caramel Architects have completed a project which both maintains the qualities of the single-family house, with a generous garden and terrace on the living level, and attains a FAR of 1.0. It is therefore more densely constructed in comparison to a multi-storey apartment block which comprises several units, but does not have any direct connection to the exterior space.

该住宅的平面尺寸十分狭窄，仅5 x 35 m，三面防火墙构成住宅的外围区，生活空间、中央庭院和集中布局的纵横阳光区紧密联系，形成了整个内部构造。

从外部进入相对封闭的白色空间雕塑，继续纵向前行到达入口处的工作室/车库、生活区、和中央庭院。尽管用地十分狭窄，但合理的纵向布局让内部空间看起来十分宽敞。

内部的工作室/车库区域以及地下室的家庭影院延续了外部的白色色调。生活区和办公区墙壁及天花板为木板图案的清水混凝土面，连续的混凝土面将内外部连接成统一的整体；铺就的木地板与墙面图案的方向一致，形成了完整的视觉效果。从工作室到厨房台阶再到上部的卧室在空间上构成了连续的统一体。相对而设的浴室和洗手间采用最小规格的紫粉色瓷砖加以区分。“房中房”的格局让视线可以毫无障碍地穿过生活区域和办公区域，到达中心的外部空间—花园。

屋顶南面的太阳能系统以及水热转换泵提供所需的能源，基本能够做到自给自足。此外，该住宅还具有高保温性，能耗很低（供热需求41 kWh/m²/a）。

This has been made possible by means of a narrow floor plan layout of 5 x 35 m, with a three-sided firewall to allow the possibility of direct extension, an internal connection between the living levels, a central atrium garden and focused horizontal and vertical lighting areas.

From the outside, one enters a relatively enclosed white spatial sculpture, which then continues to open up vertically as one proceeds from the studio / garage in the entrance area to the living area and atrium garden.In this way, an internal set of very spacious interlocking rooms is developed, despite the narrowness of the property.

The external white cube is continued as an inner white cube in the studio / garage and in the basement cinema. In the case of the living and office area located behind, the interior and exterior are connected by means of continuous fair-faced concrete surfaces with a boarding look on the walls and ceilings, as well as continuous wooden floor coverings running in the same direction as the visual effect of the boarding on the walls. This creates a spatial continuum which extends via the central kitchen landings as part of the landscape of the staircase (CJ5 = Cooking-Jay-5m wide) and the studio, to the bedroom area on the upper storey. The bathroom and toilet, which are adjoined at the side, are then respectively developed as separate islands of colour, using tiles of the smallest possible format. The ‘room in room system’ creates views through all the rooms of the living and office areas and out onto the central external element, the garden atrium.

As far as energy is concerned, the house is almost completely independent. It supplies its own needs from photovoltaic panels on the south-facing areas of the roof, and from an air-to-water heating pump. It has also been developed as a low-energy house with respect to its insulation values (heating requirements 41 kWh/m²/a).
