布里斯托的二级建筑克利夫顿大教堂（Clifton Cathedral）由英国建筑公司Purcell进行了翻新设计，约花费300万英镑。

粗野主义风格的SS. Peter和Paulwas罗马天主教大教堂，由Percy Thomas Partnership的Ron Weeks设计，并得到梵蒂冈政府的支持，于1973年完成。

Bristol's Grade II*-listed Clifton Cathedral has undergone a ￡3 million renovation, carried out by British architecture firm Purcell.
The brutalist style Roman Catholic Cathedral Church of SS. Peter and Paulwas designed by Ron Weeks of the Percy Thomas Partnership, with input from the Vatican, and completed in 1973.

建筑内部拥有可容纳1000人的空间，中间布置有一圣坛，教堂前厅包含两个由8000块独立玻璃制成的彩色玻璃窗，它于2000年正式登记在案。

在当时，这座建筑被公认为是极简主义风格，并且有着独特的六边形态，但克利夫顿大教堂却没做到完全的防水，因此45年来的自然状况对建筑造成了很大的损伤。

A congregation of up to 1,000 can assemble around its high altar, and the narthex contains two stained glass windows made from 8,000 individual pieces of glass. It was given listed status in 2000.
Although it was praised at the time for its minimalist design and unusual hexagonal plan of the sanctuary, Clifton Cathedral was never fully watertight and 45 years of leaks had caused considerable damage.

Purcell在2015年开始了这项花费310万英镑的维修过程，大教堂在整个过程中一直保持着使用状态，即每周接受八次洗礼、婚礼和葬礼仪式。

在斜屋顶上，更换了86吨铅材料。在建筑内部，有限的预算使得Purcell必须开放以前无法进入的部分空间，其中包括洗礼堂上方的画廊以及一座封闭的楼梯。

Purcell began the ￡3.1 million repair process in 2015, with the Cathedral remaining in use throughout the entire process – hosting eight masses a week along with baptisms, weddings and funerals.
Up on the pitched roof, 86 tons of lead were replaced. Internally, the funding conditions specified that Purcell had to open up parts of the building that had previously been unaccessible, including the gallery over the baptistry and opening up a sealed-off staircase.

为了表达经典的粗野主义美学，Percy Thomas Partnership最初采用了粗粒俄罗斯红木板。Purcell在修复建筑时特意保留了这个特殊元素。

Purcell布里斯托尔办公室的合伙人Clifford Martin说：“我们的信念是建筑物能够防水、安全、开放，而且保持严谨的质量，成为粗野主义的杰出代表。”

“项目的目的是维修和保护建筑，并表达其原始设计和细节。”他补充说。

“大教堂与同时期许多建筑一样，建造于困难时期。秉持原真性原则，修缮项目始终综合考虑其原始理念和可行性。”

Part of the classic Brutalist aesthetic is the cathedral's concrete form, which Percy Thomas Partnership had originally board-marked with planks of coarse-grained Russian Redwood. Purcell took care to retain this particular element when repairing the water damage.
"Our conviction was for the building to become watertight, and safe and open for use, but also not to lose any of its rigour and quality as a superb exponent of the late Brutalist era," said Clifford Martin, a partner at Purcell's Bristol office.
"The works have been undertaken with the intention to both repair and protect the building, and to magnify and celebrate its original design and detail," he added.
"The Cathedral, in common with many buildings of its type and era, was built in difficult times. Our aim for the repairs projects was, at all times, to consider what the intent for its design and execution had been in order to remain true to the building's principles."

全新的屋顶经过略微修改，解决了漏水问题，Purcell与Lead Sheet Association密切合作，创造出与建筑历史审美相匹配的持久作品。

为了找到克利夫顿大教堂混凝土护壁渗漏的原因，建筑师必须查找档案，检查原始图纸。

The new roof has been slightly modified from the original design to address the leaks, but Purcell worked closely with the Lead Sheet Association to create long-lasting work that matched the building's historic aesthetic.
To find the source of the leaks in Clifton Cathedral's concrete cladding Purcell had to delve into the archives and examine the original drawings.

建筑师研究了最初建造的覆盖层，以及每个面板的连接方法。

然后，他们能够使用与原始材料相匹配的Corennie花岗岩碎片，修复相应区域。

当玻璃脱落时，水和杂物也通过金属丝网架进入室内，因此建筑师安装了全新的自洁玻璃系统。

The architects studied how the cladding had originally been constructed and how the joints behind each panels had been made.
They were then able to repair areas where pieces had flaked or chipped off using Corennie granite chippings that matched the original materials used.
Water and draughts had also been coming in through the wire mesh glass where panes had slipped from their frames, so a new system of self-cleaning, thermally-broken glass was installed.

原有礼拜场所的照明计划并没有完全实现，因此Purcell在灯光设计技术公司的协助下运用了可调节LED灯具照明系统。

顾问建议升级供热系统，并且对整座建筑进行重新布线，提高安全性能。大教堂因此成为了干燥、温暖和光线充足的空间，供崇拜者和游客参观与使用。

The original lighting plan for the place of worship was never been fully realised, so Purcell replaced the lights with fully dimmable, ultra-bright LEDs with assistance of consultancy Lighting Design and Technology.
Consultants Method were bought in to upgrade the heating system, and the entire building was re-wired to make it safe. The Cathedral is now a dry, warm and well lit space for worshippers and visitors to enjoy.

今年已经有一些英国重要的建筑作品进行了必要的翻新。

John Puttick Associates刚刚完成了对普雷斯顿二级保护建筑粗野主义巴士站的改造，DSDHA近期也公布了二级保护项目经济学家广场的一阶项目，该广场最初由Smithsons设计。

Richard Seifert的二级保护项目Centre Point也得以修复，由Conran及其合伙人将其改造成豪华公寓。

This year has seen a number of Britain's important pieces of listed architecture undergo essential refurbishment and modernisation works.
John Puttick Associates has just completed its renovation of Preston's iconic Grade II-listed Brutalist bus station, and DSDHA has unveiled the first phase of its refit of the Grade II*-listed Smithsons-designed Economist Plaza.
Richard Seifert's Grade II-listed Centre Point has also been restored and converted from offices into luxury flats by Conran and Partners.
