塔的设计确保从这个关键的有利点，大教堂的穹顶仍然是由一个清晰的天空。包含最高质量办公空间的办公楼层采用长方形楼板的形式，其深度向顶点逐渐减小。而不是传统的中央核心提供结构稳定，该建筑采用全周边支撑管，它确定了办公室楼板的周长，并创造了风荷载下的稳定性。该循环和维修核心位于一个独立的北面塔，包括乘客和货物升降机，服务提升管和地面工厂和WCS。

The tower’s design ensures that from this key vantage point the cathedral’s dome is still framed by a clear expanse of sky. The office floors, containing the highest quality office space, take the form of rectangular floor plates which progressively diminish in depth towards the apex. Instead of a traditional central core providing structural stability, the building employs a full perimeter braced tube which defines the perimeter of the office floor plates and creates stability under wind loads. The circulation and servicing core is located in a detached north-facing tower, containing passenger and goods lifts, service risers and on-floor plant and WCs.

展示公共领域的楼板

建筑的围护结构表达了它所包含的多样性，强化了建筑的组成，并提供了主要元素的可读性。尽管这座塔占据了整个建筑，但该方案提供了前所未有的公共空间分配-低层的公共空间位于斜角上，形成了一个壮观的、阳光普照的七层高空间，其中包括商店、展览空间、柔软的景观和树木。

The building’s envelope expresses the diversity of what it encloses, reinforcing the composition and providing legibility to the primary elements. Although the tower occupies the entire site, the scheme delivers an unprecedented allocation of public space – the lower levels are recessed on a raking diagonal to create a spectacular, sunlit seven-story-high space complete with shops, exhibition space, soft landscaping and trees.

该结构的目的是加强由发展包络定义的几何，这反过来创造了独特的渐缩形式，并采取了一个周边支撑的‘管’的形式，确定了楼板的范围。梯子框架有助于建筑物的垂直强调，并包括消防核心服务于办公楼层。该框架还在视觉上锚定建筑物的地面。

The structure aims to reinforce the geometry defined by the development envelope, which in turn creates the distinctive tapering form, and takes the form of a perimeter braced ‘tube’ that defines the extent of the floor plates. The ladder frame contributes to the vertical emphasis of the building, and encloses the fire-fighting cores that serve the office floors. The frame also visually anchors the building to the ground.

这个公共空间提供了半英亩的延伸至邻近的圣海伦广场。俯瞰空间是一个公共酒吧和餐厅的玻璃电梯服务。这一新的公共空间将提供一个罕见的绿洲，在密集的城市性质的伦敦城。

This public space offers a half-acre extension to the adjacent piazza of St Helen’s Square. Overlooking the space is a public bar and restaurant served by glazed lifts. This new public space will provide a rare oasis within the dense urban character of the City of London.

 Floor Plate Plans

楼板图则

办公楼层采用简单的矩形楼板的形式，其深度向顶点逐渐减小750毫米。办公楼层与每一层的结构“管”相连，而不需要周边的二级垂直柱。

The office floors take the form of simple rectangular floor plates which progressively diminish in depth by 750 millimetres towards the apex. Office floors are connected to the structural ‘tube’ at every floor level without the need for secondary vertical columns at the perimeter.

 East Elevation

该建筑的设计是为了表达所有的组成元素背后的一个单一的玻璃信封。办公区域的正面要求最高的舒适标准与热损失，日光，眩光控制和太阳能增益有关。在这里，正面是补充了双层玻璃的内部层，形成了一个空腔，其中包含了结构框架。外部玻璃采用节点水平的通风口，允许外部空气进入并从空腔排出。在腔内控制的百叶窗自动调整，以限制不必要的太阳增益和眩光。

The building is designed to express all the constituent elements behind a single glazed envelope. Facades to the office areas require the highest comfort criteria in relation to heat loss, daylight, glare control and solar gain. Here, the facade is supplemented with an internal layer of double-glazing, forming a cavity which incorporates the structural frame. The external glazing incorporates vents at node levels to allow outside air to enter and discharge from the cavity. Controlled blinds in the cavity automatically adjust to limit unwanted solar gain and glare.

建筑物的较低层位于斜角上，形成一个向南延伸的大公共空间。

The lower levels of the building are recessed on a raking diagonal to create a large public space that opens up to the south. 

工程应于2014年夏季完工。

Construction should be completed in the summer of 2014.
