斯凯奇建筑师事务所被邀请在萨里郡法纳姆的一个陡峭的坡地上设计一个新的替代住宅。我们最初调查了部分保留原有建筑的情况，但结构检查确定现有建筑结构不适合使用。客户在早期的讨论中表示，可持续设计是一个重要的优先事项。他们还希望该建筑能与其青翠的环境相联系，并采用天然材料进行装修，玻璃窗的开窗设计能响应萨里乡村的高处景观。

Sketch Architects were approached to design a new replacement dwelling on a steeply sloping site in Farnham, Surrey. We initially investigated retaining, in part, the original building but structural examination determined that the existing building fabric was not fit for purpose. The client stated in early discussions that sustainable design was a high priority. They also wanted a building that related to its verdant setting and is finished in natural materials, with glazed openings responding to the elevated views over the Surrey countryside.

为了实现这一目标，建筑围护结构被设计成超级绝缘的，具有更高的气密性。在朝南的外墙上，光伏电池被安置在倾斜的屋顶上，与建筑机械基础设施的其他关键元素相连，包括一个中压通风系统、一个空气源热泵和一个用于储存现场能源的电池。因此，该建筑完全是电动的，其中大部分来自综合可再生资源，并且不使用天然气。

In order to achieve this the building envelope was designed to be super-insulated, with an increased level of air-tightness. On the south-facing façade, PV cells have been positioned on the pitched roof which is linked with other key elements of the building’s mechanical infrastructure including an MVHR system, an Air Source Heat Pump, and a battery for the storage of energy generated on-site. The building, therefore, is entirely electric, much of it from integrated renewable sources, and uses no natural gas.

建筑物的底层主要是居住区、餐饮空间和厨房，所有这些都是开放式的。这个空间被一个定制的钢木楼梯所点缀，该楼梯通过居住区上方的双层空间升起。睡眠空间被安置在一楼。

The ground floor of the building predominantly houses the living areas, dining space, and kitchen, all of which are open-plan. This space is punctuated by a bespoke steel and timber staircase that rises up through a double-height space above the living area. Sleeping spaces are positioned on the first floor.

一个独立的睡房位于一个由玻璃连接的 “豆荚 “结构中，其特点是用烧焦的木材和沉香的屋顶，这与主楼的天然落叶松和锌立缝形成鲜明对比。裸露的胶合木梁在天花板上表现出来，给这个空间增加了一层细节和质感。

A separate snug room is located in a ‘pod’ structure connected by a glass link and characterized as being clad in charred timber with a sedum roof, which contrasts with the natural larch and zinc standing seam on the main building. Exposed glulam beams are expressed within the ceiling adding an additional layer of detail and texture to this space.

屋主希望以更可持续的方式建造和生活–织物的设计和确保其在现场的正确建造是非常重要的，尽量使建筑具有良好的绝缘和气密性。 我们尽可能地使用可回收材料，在需要使用混凝土的地方，我们不使用水泥。我们还安装了一个机械通风和热回收装置，以及空气源热泵、太阳能电池板和电池，以减少建筑的运行成本。我们从这个项目中学到了很多东西，并不断努力提高我们建筑的效率，从绝缘、气密性、尽量减少冷桥和通过遮阳减少过热开始。

The homeowners were looking to build and live more sustainably – The design of the fabric and making sure it is constructed correctly on site is hugely important, trying to make the building as well insulated and airtight as possible. We used recycled materials where possible and where we needed to use concrete it was cement free. We also installed a mechanical ventilation and heat recovery unit, along with an Airsource heat pump, solar panels, and a battery to reduce the running costs of the building. We have learned a lot from this project and are constantly trying to improve the efficiency of our buildings starting from the insulation, airtightness, minimizing cold bridging, and reducing overheating through solar shading.
