Manber Jeffries House是一个复杂的、单层的、后方的、侧面的扩建项目，是位于伦敦Willesden Green的一个实质性的、半独立的、维多利亚式的别墅的底层公寓。该项目由James Alder在2021年3月完成，对该房产现有底层的一小块区域进行了改造，还提供了一个新的厨房和餐厅扩展，同时作为家庭的拱形花园房间。
Manber Jeffries House is an intricate, single-story, rear, and side extension to the ground floor flat of a substantial, semi-detached, Victorian villa in Willesden Green, London. The project, completed by James Alder in March of 2021, reworks a small area of the existing ground floor of the property and also provides a new kitchen and dining room extension that simultaneously operates as a vaulted garden room for the home.
扩建部分的屋顶线条落在内部循环的要求内，使扩建部分能够处理好从现有房产底层的高位到花园以外的低位的过渡。扩建部分也被设计成高度下降，以配合和联系现有的倾斜建筑的陡峭坡度，它以前包含一个非常小的厨房。
The roof lines of the extension fall within the internal circulation requirements, allowing the extension to manage the transition from the high level of the existing property’s ground floor to the lower level of the garden beyond. The extension is also designed to fall in height, to match and relate to the steep pitch of an existing lean-to construction, which had previously contained a very small kitchen.
该项目的关键是保留和扩展一个实质性的砖墙，它在历史上曾支持过一对对称的倾斜的花园外墙和厕所。这些建筑已经被半拆除了，并且在最近几十年里被严重忽视了。维多利亚时代的玻璃温室和附属花园建筑，作为正式花园的边界墙的附属物，对项目的形式语言和材料都形成了特别强烈的启发。
Key to the project was the retention and extension of a substantial brick party wall that had historically supported a symmetrical pair of pitched garden outbuildings and lavatories. These were already semi-demolished and had been heavily neglected in recent decades. Victorian glasshouses and ancillary garden buildings, built as appendages to the boundary walls of formal gardens, formed a particularly strong inspiration for both the formal language and the materiality of the project.
预算的限制要求对标准化的建筑构件进行极端严格的使用，以形成两个对比鲜明的表皮，在外部和内部形成一个雄心勃勃的钢结构框架结构。虽然有很大的相互依赖性，但红色外墙的开口在直接与主楼或侧墙对接时，会滑过后面的钢结构工程。主体财产的拆除被有意地保持在最低限度。
Budgetary constraints demanded that extreme rigor be applied to the informed use of standardized building components to form two contrasting skins that externally and internally line an ambitious structural steel framing configuration. Although heavily interdependent, the openings of the red outer façade slide past the structural steelwork behind when they directly interface with either the host property or the party wall. Demolition of the host property was purposefully kept to a minimum.
裸露的钢结构支撑着复杂的屋顶几何形状，并向两个方向倾斜，形成一个精心设计的构造，形成通往花园的开口。对细节的关注以及对鲜明的、有层次的建筑的刻意诚实和赞美贯穿始终。
The exposed steelwork supports a complex roof geometry and cantilevers in two directions to form an elaborate tectonic to the forming of openings to the garden beyond. A focus on detail and a deliberate honesty and celebration of stark, layered construction are employed throughout.
