项目坐落于伦敦地标建筑云集的帕丁顿盆地，由Derwent London出资，Fletcher Priest事务所设计建造，是一栋17层的全新商务办公楼。项目紧邻布鲁内尔首座大桥，在大厦上，人们可以俯瞰运河全景以及伊萨伯德王国布鲁内尔大西部铁路的终点站 —— 帕丁顿车站。此外，项目场地还邻近A40高架高速公路以及新开运的跨城铁路伊丽莎白线的站点。场地下方是拥有百年历史的伦敦地铁隧道。
There can be few areas in London where so many engineering landmarks rub shoulders. Derwent London’s Brunel Building, a 17-storey new-build workplace building designed by Fletcher Priest, overlooks the Grand Union Canal and Paddington Station, the London terminus to Isambard Kingdom Brunel’s Great Western Railway, and is next to the site of Brunel’s first ever bridge. The elevated A40 expressway runs past and the Elizabeth Line, the new cross-London railway, stops near-by. One hundred- year-old cast-iron subway tunnels run beneath the site.

The existing building on the site spanned this section of the canal blocking access and views along the canal. The canal-side walk is now publicly accessible for the first time in more than 200 years and will eventually provide new pedestrian routes to nearby Little Venice, as well as a new public space and artwork. Brunel Building is one of surprisingly few canal-side developments in London with its main entrance on a canal.

独特的地理环境与悠久的历史底蕴奠定了布鲁内尔大厦的风格基调。设计理念旨在为大厦开发创新型的工作空间，吸引目标人群，并强调出该地区的重要性与便利性。Derwent London公司的Simon Silver解释道：“我们力求坚固稳定的结构形式，以体现出伟大的工程师布鲁内尔(Brunel) 的工匠精神。”
This unique and evocative context sets the tone for the design of Brunel Building. The brief called for a development with innovative workspace which would attract occupiers, as well as highlighting the significance and amenity of the area. “We agreed that the design demanded a robust construction which would embody the spirit of the great engineer Brunel”, explains Derwent’s Simon Silver.

The external structure shades windows, allowing larger areas of glazing and deep daylight penetration. Beams are tapered as they approach the facade, permitting the use of taller perimeter glazing and further increasing daylight. This impression of light and space is further enhanced by the high floor- to-ceiling dimensions. Fletcher Priest and Arup worked with building services engineer Cundall to integrate the floor structure and services into as tight a zone as possible, some 100mm less than normal for workplace buildings, to further increase ceiling heights.

The solution was also technically driven by the presence of the canal and two Bakerloo Line underground tunnels running across one corner of the site. Working with Arup, Fletcher Priest’s proposal for a steel diagrid exoskeleton refers to Brunel’s now lost Great Western Railway viaducts. It is not only visually arresting but allows the building to span the tube lines. The building is pulled back at this corner to reduce loading, while a line of piles between the two tunnels helps to distribute foundation loads.

“布鲁内尔大厦本身就是展示其建造过程的最好说明。项目的设计策略通过暴露在外的结构淋漓尽致地展现了出来。突出的机械与结构元素，以及从运河边到建筑内部的公用电梯被喷涂成充满活力的橙色，其灵感源自河边的安全设施。”Fletcher Priest事务所创始人Keith Priest说道。
“Building services have been left on display throughout, to reveal how the building has been constructed. This strategy is most emphatically revealed through the exposed external structure, while vibrant orange, inspired by waterside safety equipment, was chosen to highlight mechanical and structural elements and canal-side public lifts”, says Fletcher Priest partner, Keith Priest.

Meanwhile, occupiers have access to two expansive roof terraces with views across London. Soft landscaping, planters with wildflowers, trees and nesting boxes all contribute toward re-establishing the local ecology in what was previously a light- industrial area. Environment and social sustainability were central to the ambitions of both design team and client. The complex external diagrid structure provides 20% shading to the facades, helping to reduce energy demand. An Aquifer Thermal Energy Store (ATES), with two forty-storey deep boreholes, provides low- carbon heating and cooling. Grey water from showers is recycled to flush the building’s bathrooms. Exposed undersides of the structural precast concrete floor panels, made in a state-of-the-art robotic plant, help to deliver comfortable interior thermal gradients and more volume per person. Leaving the ceilings exposed also saved more than 540 tonnes of embodied carbon. More than 90% of construction waste was recycled and ground blast-furnace slag (a waste product from iron and steel production) was used in the concrete.

Motorized hangar-sized glazed sliding doors can be rolled back to provide an extension to the new tree-lined towpath walkway. Passers-by can visit the canal-side restaurant café and bar and view the public art in the triple-height reception concourse.

Pushing the superstructure to the outside of the 32,912 sqm building delivers column-free internal floor space – spanning 12-16m to the dispersed central cores and 66m from end to end. Occupiers can have maximum flexibility with their fit-outs and enjoy unimpeded views. This aesthetic means that materials such as concrete, steel and sawn oak have been left exposed internally, and service ducts and pipes are visible. Extra emphasis has been put on the quality of construction – a particular challenge in areas such as the core, where huge areas of concrete required a consistent finish, and had to remain protected during construction.

精心制作的全尺寸实体模型和集成数字建模成为关键的设计工具。功能如此丰富，结构如此复杂的建筑，耗时三年，只能通过利用最新的数字技术来开发和协调设计，制造管理，工程物流等来完成。“工程模拟以及VR技术将设计可视化，使我们能够更加直观地了解到设计师与供应商之间是否存在冲突，便于我们进行项目整体的把控与评估，比如穿梁管道的架设就是一个很好的例子。”Fletcher Priest合伙人Chris Radley说道。
Extensive full-scale physical mock-ups and integrated digital modelling became key design tools. Such a rich and complex building, which took three years to construct, could only be delivered by harnessing the latest digital tools, developing and coordinating the design, and managing the logistics for fabrication and construction. “We could visualise the design via simulated walkthroughs and virtual reality headsets, enabling the architects, designers and suppliers to check for clashes, such as pipework running through beams, so we could make and assess changes holistically,” says Fletcher Priest associate Chris Radley.
