架构师提供的文本描述。多塞特路24A是位于伦敦北部亚历山德拉宫的一座两间卧室的小房子，加上一座风景如画的维多利亚式农舍，最初是为铁路工人建造的。这些客户在那里住了20年，喜欢这条路，利用这个机会卖掉了他们的旧房子，但保留了一个附属车库，成为他们新房子的所在地。我们的简报是建立一个简单的，现代的家，充满了光。

Text description provided by the architects. 24a Dorset Road is a small two bedroomed house in Alexandra Palace, north London, added onto a terrace of picturesque Victorian cottages originally built for railway workers. The clients had lived there for twenty years, loved the road and took the opportunity to sell their old house, but keep an attached garage, which became the site for their new house. Our brief was to make a simple, contemporary home, filled with light.

露台是在当地列出的，因此我们知道我们将面临相当严格的规划限制，但很快就可以看出，保护官员除了一个精确的复制品小屋外，什么也不接受。增加一个小后延伸被拒绝许可，但随后赢得上诉，这增加了足迹，但仍然是适度的76平方米。它给我们留下了一个有趣的挑战，那就是如何在传统小屋的外壳内设计出一套连贯的现代房屋。

The terrace was locally listed so we knew that we would be up against reasonably strict planning restrictions, but it soon became apparent that the conservation officer would not accept anything other than an exact replica cottage. The addition of a small rear extension was refused permission but subsequently won on appeal and this increased the footprint to a still modest 76sqm. It left us with an interesting challenge of how to design a coherent modern house within the shell of a traditional cottage.

尽管现有的露台很受欢迎，但它的正面很匀称，有着优质的Gaunt砖墙，或许最有帮助的是底层2.7米高的天花板，我们首先把它延伸到阁楼空间，增加到320万。邻居们对新房子有多大感到惊讶，这让我们对楼面面积和楼顶高度之间的关系提出了有趣的问题，尤其是在伦敦的楼面空间如此昂贵的情况下-这种情况似乎不大可能改变。

The existing terrace though has much in its favour, well proportioned facades with good quality Gaunt brickwork, and perhaps most helpful of all, generous ceiling heights of 2.7m on the ground floor, which we increased to 3.2m on first by extending into the loft space. Neighbours are surprised at how large the new house feels which for us raised interesting questions about the relationship between floor areas and head heights, particularly when floor space in London is at such a premium- a situation which seems unlikely to change.

一楼的高度也允许将一个睡架插入前卧室。客户的想法，这使得房间是多功能的，要么是办公室，要么是客房。通过一个可移动的梯子，它有一个有趣的圆形窗口设置在山墙的一端，特别受客户的孙子们的欢迎。

The height on the first floor also allowed a sleeping shelf to be inserted into the front bedroom. The clients’ idea, this allows the room to be multifunctional, either an office or guest bedroom. Accessed via a removable ladder it has a playful round window set into the gable end and is particularly popular with the clients’ grandchildren.

在楼梯上方，建筑物的全部高度被一条一直延伸到山脊的8米长的光环所暴露。在一所小房子里，这是一个令人惊讶的空间。它被漆好的木板和上面的锥形石膏板竖井所覆盖，照亮了楼梯和起居室的后部，而起居室的后部只有一扇低矮的平房窗户。晚上，一盏吊灯挂在一根钢棒上，把一个图案扔到墙上，在一座原本低调的房子里提供了一种迷人的瞬间。浴室中使用了一种较小版本的光环，它还用内设的橡木架子绘制木材板以形成储存和装箱。

Above the stairs the full height of the building is exposed by a lightwell which extends 8m right up to the ridge. It is a surprising space to find in a small house. Clad with painted timber boards and with a tapered plasterboard shaft above, it lights the stair as well the back of the living room which is otherwise only served by a low cottage window. At night, a chandelier hung from a steel rod throws a pattern onto the walls to provide a moment of glamour in an otherwise understated house. A smaller version of the lightwell is used in the bathroom which also has painted timber boards to form storage and boxing out, with inset oak shelves.

 Floor Plan

在底层，起居和用餐空间是开放的，但是一个独立的厨房，一个有镶板墙的厨房，在一边为生活空间创造了一个封闭的空间，而另一边则是非常需要的厨房储藏室。回收的橡木横梁横跨它和支持第一层的托梁，这是暴露和支撑人字形支柱。该结构显然是独立地延伸到厨房，加强了一楼作为一个空间的感觉。

On the ground floor the living and dining spaces are open plan, but a free-standing kitchen with a paneled wall creates an enclosure to the living space on one side, and much needed kitchen storage on the other. A reclaimed Oak beam spans over it and supports the first floor joists, which are exposed and braced with herringbone struts. The structure clearly continues independently over the kitchen, reinforcing the sense of the ground floor as one space.

裸露的托梁意在让人想起维多利亚时代的仓库，或拆迁过程中发现的建筑，并借此营造一种特殊的气氛，并通过仔细使用具有历史内涵的其他材料，如油漆木板和厨房地板上的黑白瓷砖，加以加强。虽然结构看起来简单，它是仔细详细的柔韧梁与隐藏钢板修整楼梯开口，和墙壁上的浴室自给，以避免双重托梁。

The exposed joist are intended to be reminiscent of Victorian warehouses, or of structure uncovered during demolition and lend a particular atmosphere, reinforced by the careful use of other materials with historical connotations, such as the painted timber boarding and the black and white tiles on the kitchen floor. Whilst the structure looks simple it was carefully detailed with flitch beams with hidden steel plates trimming the stair opening, and the wall to the bathroom above self-supporting to avoid a double joist.

在厨房的一侧，一个公用室和厕所隐藏在全高度单位的后面，并通过一个离散的滑动门进入。一个平顶灯，法式门和玻璃侧门为餐厅提供了充足的光线，一个突出的窗户创造了一个有用的架子，用来存放厨房水槽收集的不可避免的用具。

To the side of the kitchen a utility room and WC are hidden behind full height units and accessed through a discrete sliding door. A flush rooflight, French doors and glazed side door provide plenty of light into the dining space and a projecting window creates a useful shelf for storing the inevitable paraphernalia that collects by the kitchen sink.

为了符合L部的要求，该建筑物依赖于高水平的绝缘和气密性，而不需要任何机械系统。这是通过使用绝缘木框架，内部一层多箔绝缘，这意味着U值0.15是可能的，只有360毫米的建设。从墙壁到屋顶的绝缘是连续的，使气密性更容易实现。

To comply with Part L the building relies on high levels of insulation and air tightness, without the need for any mechanical systems. This was achieved by using an insulated timber frame, with an internal layer of multi-foil insulation, which meant that a U-value of 0.15 was possible with a build up of only 360mm. The insulation is continuous from walls to roof, making airtightness easier to achieve.

在花园里，一个“拼凑”的甘特砖被用来形成一个后阳台和一条通往前门的小径。前面花园的其余部分被用作蔬菜地，布列登砾石围绕着橡木铁路露台形成的凸起的床，向露台的原始居民点头。我们最近在房子的一侧增加了一个倾斜的棚子.瓦尼边缘橡木板和半透明波纹玻璃钢屋顶，它提供了一个有用的存储空间，以取代车库，曾经站在现场。

In the garden a ‘patchwork’ of Gaunt brickwork is used to form a rear terrace and a path to the front door. The remainder of the front garden is used as a vegetable patch with Breedon gravel set around raised beds formed from oak railway sleepers, a nod to the original inhabitants of the terrace. We recently added a lean-to shed to the side of the house. Clad with waney edge oak boards and with a translucent corrugated GRP roof, it provides a useful storage space to replace the garage that once stood on the site.
