Strata SE1 is a 148m high 43-storey residential tower that forms a dynamic new addition to the London skyline. It has 408 apartments offering a mix of market (310) and intermediate housing (98) in the form of shared-equity affordable dwellings. The first building in the world with integral wind turbines, it also sets a new benchmark in terms of environmental strategy.

The project team worked closely with client Brookfield and engineers WSP to refine the original scheme in terms of the core in relation to common spaces, with the use of post-tension slabs further reducing slab thickness, enabling greater floor-to-floor heights, and to eventually develop a high-performance, three-layer, aluminium-and-glass façade.

Environmentally, the adoption of 200mm thick post-tensioned concrete floor slabs and high strength blade columns saved over 2,000m3of concrete and 1,800 t of CO2. This CO2reduction is the equivalent of emissions from energy that the apartments will use over four years.

The main entrance looks towards the core regeneration. This entrance is prominent and set back from the main pedestrian thoroughfare adjacent to Walworth Road, enhancing the sense of arrival. The double-height lobby beyond allows for a gradual reduction in scale from outside to inside, further bridging the transition from public to private space.

The central bank of three lifts faces the entrance, providing a clear and unambiguous means of accessing the upper levels and reaching the residential levels. There are no dark corridors on the residential levels and each flat is accessed via short entrance halls off the main lobby to individual front doors.

The final configuration enlarged and defined a series of linked pedestrian friendly spaces at ground floor level, each with its own unique character, providing much-needed permeability across the site. The orientation, scale, slenderness, articulation of its top and grain of its distinctive cladding are designed to both make their mark on the London skyline as well as create a strong sense of human scale that engages the public when viewed from close-up.

Strata SE1风力供电住宅大楼高148m、共43层楼，有408间公寓，其中有310间普通公寓和98间中等公寓，均为百姓能负担得起的平价住房。它是伦敦市天际线上新增的一道亮丽风景线，同时也是世界上首栋自带风力涡轮发电机的建筑，为环保设计和开发树立了建筑史上的新标准。

项目团队在和客户布鲁克菲尔德以及工程组WSP协商后，决定改进原始方案里的核心部分，在公共空间使用后张预应力楼板，进一步降低楼板的厚度，增加楼面与楼面间的高度，最终打造出一个三层铝结构的高品质玻璃立面。

就环保方面来说，建筑本体的结构采用了200mm厚的后张预应力楼板及高强度刀柱，减少了近2000m3的混凝土的使用和相当于本公寓楼四年以上的多达1800 t的二氧化碳排放量。

建筑的主入口直通改进后的核心区域。主入口毗邻沃尔沃思路，设在人行道上并向里缩进，让客人感觉宾至如归。双高大堂从外到内逐渐缩小，实现了公共空间与私人空间之间的自然过渡。

大堂中央有三部正对入口的电梯，使住户能简单方便地直达高层和公寓层。公寓层不会有光线昏暗的走廊，每个公寓都可以经由大堂内另设相应的较小的入口门厅，直达不同的公寓单元。

在最后的结构配置上，建筑的首层扩建并划分了一系列相互联系的空间，为行人提供服务。每个空间都独具个性，相互渗透，相辅相成。设计的方向、规模、细长度、屋顶的接合，以及独特的包层，这些都将成为伦敦天际线的一道标志，同时，在近距离观看时，为建筑创造了强烈的人文感，吸引大众的视线。

FEATURE 特点分析

Façade

The façade's sculpted effect and range of glazing shapes allow a wide variety of views from the light - filled apartments and help break up Strata's overall sense of mass. The language created by the façade adds a strong sense of hierarchy to the architectural order of this residential building. Hence, the overall form can enjoy a clearly articulated base, middle and top zone. At the base of the building, outer layers have been peeled back to reveal glazing and create transparency for the retail and entrance to the building. At the top of the building, a similar approach has been taken to reveal a crystalline apex.

立面

立面的雕塑外观和玻璃幕墙的组合让所有公寓都能在沐浴在自然光中的同时还能欣赏到广阔的风景，同时有利于打破大楼体量的整体感，立面的表达形式力求为公寓楼的结构顺序增添更强烈的层次感。因此，建筑的整体形态清晰地展示了其底部、中部和顶部区域的构造。建筑的底部去掉外层表皮，显露出的玻璃幕墙使建筑入口和零售区更显通透；建筑的顶部也采取了类似的方法，显露出它的水晶尖顶。
