凱里喬大教堂位于肯尼亞內羅畢西南約250公里處，于2015年底竣工。它位于東非大裂谷以西的高地上，可欣賞整個茶園和周圍山丘的壯麗景色。該教區成立于1995年，由最受人尊敬的主教Emmanuel Okombo領導。

教堂的設計創造了一個獨特而神圣的地方，在一個巨大的統一屋頂下，可容納1 500名教徒坐在這里參加羅馬天主教彌撒的禮拜儀式。引人注目的斜屋頂和其上升的內部體量——超過1 375平方米的大小——是其設計背后的關鍵特征。

主教Emmanuel特別關注擴寬中殿，因為它接近圣壇，要以最大程度地促進會眾與群眾的慶祝活動及其高潮，即圣餐儀式。它沿著兩個側廊完全開放，以促進自然通風，并允許會眾在多個地點離開建筑，轉移到景觀露臺和花園。

我們的愿望是創造一種在美學和功能上都能與景觀無縫融合的結構。大教堂的磚瓦屋頂現在已成為凱里喬丘陵和山谷全景中的一種獨特形式。

建筑方面的挑戰是確保凱里喬大教堂體現天主教的禮拜儀式，并以一種服務于信仰和當地社區特殊品質的方式擁抱當地的會眾。我們相信我們的回應是獨特的，并且受到普遍歡迎。

巨大屋檐下的拱形上升空間參考融合了非洲和教會的歷史。教堂空間的塑造和建筑結構的表達都非常用心和嚴謹——石頭底座、簡單的鉸接、拱形混凝土框架和木肋拱頂以一種精巧而誠實的方式暴露在外。

該建筑采用簡單的天然材料，以對這個非洲農村社區的信仰和節儉表示敬意。除了彩色玻璃使用的玻璃板以外，所有的材料，包括用于天花板、門和家具的柏木（在凱里喬種植），以及屋頂上的粘土瓦，都是就地取材和制作的。天花板由指狀連接的柏木板條構成，旨在適應當地環境的高濕度。

用于圣殿的花崗巖來自肯尼亞，用于雕像的肥皂石來自位于凱里喬以南的基西族鎮。地板是用機器切割的內羅畢藍石鋪成的。

在整個施工期間，我們一直致力于讓熟練的技工參與進來，并提高當地的施工技能。其中一些技巧被用在大教堂內外的藝術品上，如引人注目的馬賽克。工藝技巧的使用還幫助設計完成屋頂的教堂圖案，該屋頂由約翰·克拉克設計，由當地工人安裝。

建筑物復雜的幾何結構通過肯尼亞特有的現場施工方法進行調整。每個不同尺寸的結構框架都需要復雜的混凝土澆注系統來完成。該建筑的外墻材料被精心挑選為水洗水磨石，以其自潔特性而聞名，并通過手工施工。平臺上的內羅畢藍石包層由當地泥瓦匠手工裝飾和固定。

可建造性和對當地資源的利用是凱里喬大教堂的主要驅動力。該項目設計旨在適度的能源運行，充分使用自然采光，維護需求少。因此，其在可持續性方面的主要影響是建造材料，以及在建造過程中采購和管理這些材料的方式。另一個主要目標是最大程度地減少能源消耗，從而減少建筑物的維護成本和費用。

Completed at the end of 2015， Kericho Cathedral is located in Kenya， approximately 250km South-West of Nairobi. It lies within the Highlands， west of the Great Rift Valley， enjoying magni cent views across tea plantations and surrounding hills. The Diocese was established in 1995 with a growing congregation and is led by the Most Reverend Bishop Emmanuel Okombo.

The Cathedral’s design creates a unique and sacred place for a congregation of 1，500 seated celebrants participating in the liturgy of the Roman Catholic Mass under one giant unifying roof. The strikingly inclined roof and its ascending interior volume - over 1，375 square metres in size - are the key characteristics behind its design.

Bishop Emmanuel was particularly concerned to widen the nave as it approaches the altar to maximise the congregation’s engagement with the celebration of the Mass and its climax， the Act of Communion. It opens completely along both transepts to promote natural ventilation and allow the congregation to leave the building at multiple points and expand onto the landscaped terraces and gardens.

The aspiration was to create a structure that integrated seamlessly with its landscape setting， in both aesthetic and functional terms. The Cathedral’s tiled-roof is now a distinctive form in the rolling panorama of Kericho’s hills and valleys.

The architectural challenge has been to ensure Kericho Cathedral embodied the Catholic liturgy and embraced its local congregation in a way that serves the Faith and the special qualities of its location and community. We believe our response is distinctive and universally welcoming.

The ascending vaulted volume contained under a vast roof fuses African and ecclesiastically historic references. Care has been taken to shape the Cathedral’s space and express the building’s structure - the stone plinth， simply articulated， arched concrete frames and timber-ribbed vaulting are exposed in a strikingly crafted and honest manner.

The building’s simple palette of natural materials honours the faith and frugality of this rural African community. With the exception of the glass sheets used by the stained-glass artist， all the materials， including the Cypress timber （grown in Kericho）， which was used for the ceiling， doors and furniture， and the clay tiles in the roof， were locally resourced and fabricated. The ceiling was constructed from finger-jointed Cypress timber slats， designed to accommodate the high range of humidity of the local environment.

The granite used for the sanctuary was sourced from Kenya， and the soap stone used for the statues was sourced from the town of Kisii， located south of Kericho. The ooring was laid from the machine- cut Nairobi Blue stone.

The practice has been committed to the involvement of skilled artisan trades and the improvement of local skills throughout the construction period. Some of these skills were used in the artwork situated in and around the Cathedral such as the striking mosaic on display. In addition the use of craft skills has assisted in the design of the ecclesiastical pattern for the roof which was designed by John Clark and was installed by local labourers.

The complex geometry of the building was accommodated by an in-situ construction method specific to Kenya. The size of each structural frame required a complex pouring system for the concrete. The building’s cladding material was carefully selected as washed terrazzo， known for its self-cleaning attributes and was applied by hand. The Nairobi blue stone cladding of the podium was hand-dressed and fixed by local masons.

Buildability and the use of available local resources were key drivers for Kericho Cathedral. The project is designed to operate with modest energy， using natural daylight and few maintenance requirements. Its major impact in sustainability terms is therefore the materials with which it has been constructed， and the way they have been procured and managed through the construction process. Another key ambition was to minimise energy use， and consequently， reduce the building’s maintenance cost and obligations.
