Next up in our high-tech architecture guide, we look at Portcullis House in London, which demonstrated how the style could be used in historically sensitive locations.

Built opposite the Palace of Westminster, Portcullis House is an office building designed by Michael and Patty Hopkins’ studio, now called Hopkins Architects, as offices for the UK Parliament.

The building is six-storeys high and, like other buildings of the high-tech architecture style, has its services and structure expressed externally.

In the case of Portcullis House, this is marked by a roof lined with ventilation chimneys, a glass-roofed atrium and a robust substructure that is visible within the London Underground tube station it sits above.

接下來,在我們的高科技建築指南中,我們看一下位於倫敦的Portcullis House,它展示瞭如何在歷史悠久的敏感地點使用這種風格。

Portcullis House建於威斯敏斯特宮對面,是一棟辦公樓,由邁克爾和帕蒂·霍普金斯工作室(現稱為霍普金斯建築師事務所)設計,為英國國會辦公室。


就Portcullis House而言,其特點是屋頂襯有通風煙囪,玻璃屋頂的中庭以及位於其上方的倫敦地鐵站內可見的堅固的下部結構。

Portcullis House was the result of a space audit of parliament carried out by the Hopkins’ studio in 1988, which suggested there was an urgent need for more office space for members of parliament (MPs).

Four years later, Parliament commissioned the studio to develop the office to accommodate 213 MPs and their staff.

The brief demanded an ultra-low energy building, which would also complement its setting in a UNESCO World Heritage Site alongside the Palace of Westminster. The Palace includes the Houses of Parliament and London landmarks such as Elizabeth Tower, often referred to as Big Ben.

It also asked that the building be designed in conjunction with the Westminster tube station, which was built directly below the building.

Portcullis House是霍普金斯工作室於1988年對議會進行空間審核的結果,這表明迫切需要為國會議員(MPs)提供更多辦公空間。


簡介要求使用超低能耗的建築,這也將補充其在威斯敏斯特宮旁被聯合國教科文組織列為世界遺產的建築的環境。 宮殿包括國會大廈和倫敦地標,例如伊麗莎白塔,通常被稱為大笨鐘。


Porticullis House was designed with structural engineer Arup, and is built largely from prefabricated elements – a staple of high-tech architecture – which allowed for quick assembly.

Its form and structure is organised around a central atrium, which is positioned in line with the ticket hall of the Westminster Underground station.

Porticullis House由結構工程師Arup設計,主要由預製構件(高科技建築的主要組成部分)建造而成,可快速組裝。


The building is supported by six huge foundation piles, which extend down through the station’s ticket hall.

Where these piles meet the courtyard, they emerge above ground to support a series of concrete arches that form the sides of the atrium.

The arches also provide structural support for a huge glass canopy that covers the atrium and is further supported by a grid of steel and oak.




The high-tech style of Portcullis House is also evident externally, where fourteen tall, bronze chimneys line its roof. Thirteen of these chimneys are used for natural ventilation, while the fourteenth is a flue for mechanical systems.

They are all positioned on the roof due to a lack of underground space, but by echoing the aesthetic of the chimneys of the adjacent Norman Shaw building and Palace of Westminster, they help the building relate to its setting.

The chimneys are positioned on top of a series of box girders that double as air ducts and form a spider-like pattern on its roof. These box girders then rest on prestressed sandstone columns expressed on the building’s facade.

Between the sandstone columns, the studio also developed prefabricated high-tech cladding, including ducting, windows, sun-shading and a “light shelf”.

Portcullis House的高科技風格在外部也很明顯,屋頂上排列著十四個高大的青銅煙囪。 這些煙囪中有13個用於自然通風,而第14個是機械系統的煙道。

由於缺乏地下空間,它們都位於屋頂上,但是通過呼應相鄰的Norman Shaw大樓和威斯敏斯特宮的煙囪的美感,它們幫助大樓與其環境相關。

煙囪位於一系列箱形樑的頂部,這些箱形梁兼作風管,並在其屋頂上形成蜘蛛狀的圖案。 然後,這些箱形梁擱置在建築物正面上的預應力砂岩柱上。


The atrium is complete with trees and water features, with a secure underpass that links the courtyard to the Houses of Parliament.

The rest of the ground floor, which surrounds the atrium, features an open arcade that extends along the two street frontages, sheltering the entrance to the tube station and a row of shops.



The upper floors of Portcullis House are populated with offices around its perimeter, which tail off from a corridor that looks down into the atrium through the glass roof.

All the interior finishes are designed to look and feel like a ship – with bowed windows and light oak finishing.

Portcullis House is complete with boreholes that use groundwater for cooling, which is one of the reasons it received a BREEAM Excellent rating – the highest available at the time of its completion. It was also nominated for the 2001 Stirling Prize.

Portcullis House的較高樓層周圍遍布辦公室,這些辦公室從走廊的末端穿過,走廊從玻璃屋頂向下俯瞰中庭。


Portcullis House的鑽孔使用地下水進行冷卻,這是它獲得BREEAM優秀評級的原因之一-竣工時可獲得最高評級。 它還獲得了2001年斯特林獎提名。
