Nex- Architecture與木結(jié)構專家Xylotek合作，打造了一系列創(chuàng)新式層壓橡木涼亭，點亮了倫敦攝政廣場的公共空間。攝政廣場位于攝政公園東側(cè)，尤思頓車站以西，是多功能的商業(yè)居住項目，由British Land在20世紀90年代中期開發(fā)。

涼亭采用了天然材料和木質(zhì)街具，配以大面積的植物，從設計上呼應了British Land振興攝政廣場內(nèi)外的公共空間和人行步道的愿景。三座新的半遮蔽涼亭供人們與朋友、同事閑坐放松，也可用于戶外戲劇音樂表演，讓穿過攝政廣場的路人從尤斯頓路的快節(jié)奏中解放出來。

近期，攝政廣場園區(qū)的企業(yè)租戶已從藍籌企業(yè)轉(zhuǎn)變?yōu)槊襟w、科技和生命科學企業(yè)，這推動了對辦公建筑的更新改造及對環(huán)境效能的提升，呈現(xiàn)出更貼合當代需求，煥然一新的工作空間。

新的租戶為園區(qū)帶來的年輕人群渴望更具活力的舒適空間。新冠疫情進一步推動了British Land對攝政廣場整體空間自然健康的舒適度的提升。在受邀的設計競賽中，建筑師面臨的挑戰(zhàn)是為租戶打造一個更受歡迎的場所，同時激活攝政廣場與周圍街道間的聯(lián)系。

大自然是設計的靈感來源，林中偶然邂逅的木柴捆賦予了攝政廣場三座涼亭啟發(fā)。細長的橡木條匯集成精致的格子，與茂盛的植物一起將訪客環(huán)繞在其中。兩座較大的涼亭呈圓形，中間的圓孔開口將人們的關注從地面上的植物引向天空。

三座涼亭的規(guī)模自西向東逐漸增大。第一座邀請人們匯集于此，閑坐交流。第二座在道路中心布置了大型的圓形旋轉(zhuǎn)座椅，邀請大人兒童前來玩耍。最后一座涼亭則為當?shù)貏F打造了一座新的階梯式表演空間，在夜間及周末還可作為音樂場所使用。

涼亭的完工提升了攝政廣場公共區(qū)域的改造。不論是工作生活在園區(qū)的人們，還是路人都擁有了多種全新的方式聚集于此。自然以富有想象力的方式引入開發(fā)的中心，Townsends打造的景觀提升了該地的生物多樣性。

通過概念草圖、模型研究和VR模擬技術，Nex- Architecture在設計早期便確立了涼亭的形狀、規(guī)模和位置。之后與負責設計至生產(chǎn)步驟的合作方Xylotek共同完成了研究計算，將不規(guī)則的格子結(jié)構打造成薄橡木板條組成的嚴謹而不均勻的幾何造型。

Xylotek所面臨的關鍵挑戰(zhàn)是完成結(jié)構的設計，從而讓木板條保持纖細造型同時能夠為格子結(jié)構提供支撐。最終設計采用了場外生產(chǎn)的形式提升工藝質(zhì)量，減少浪費并縮短現(xiàn)場組裝的時間。可持續(xù)生產(chǎn)來源的橡木應用其中，細條彎曲后進行了層壓塑形。最終層壓條疊成格子被運送至現(xiàn)場，與松散的板條組裝起來。

? Luke Hayes

看似富有想象力但毫不費力的自然趣味造型，需要結(jié)構和裝配的獨創(chuàng)性以及對細節(jié)的極度關注。構成每個亭子的板條分四層排列，交替層朝著相反方向旋轉(zhuǎn)。每一層的板條都具有相似的測地曲線形狀，意味著可由原本筆直的橡木細條打造。一層中的所有板條都可以在單個彎曲夾具上完成，而視覺差異是通過隨機覆蓋的重復圖案改變板條長度來實現(xiàn)的，從而在規(guī)則的底層圖案和自然變化間營造出視覺效果。

項目共采用了400余塊橡木板條，總長度超過10公里。每塊橡木板條由五層8毫米的薄板壓成，橫截面為65x40毫米。通過將短橡木兩端指接，可以創(chuàng)建長達9.5米的薄板。膠合層壓工序在Xylotek位于布里斯托爾的工作坊中定制的分析夾具上完成，每個涼亭的分段都在這里進行預組裝，現(xiàn)場定位并覆以更多的板條蓋來打造出彎曲完整的3D格子造型。

入口的拱門也由膠合橡木板以最為契合涼亭的復雜曲率和單向彎曲形式支撐。表層的處理工藝增強了材料的耐用性和防火性能。

A New Way In - Public realm transformed with timber

Nex- Architecture has collaborated with Xylotek advanced timber structure specialists to create a sequence of inventive laminated oak pavilions newly enhancing the public spaces of London's Regent's Place.?Lying east of Regent's Park and west of Euston station, Regent's Place is a mixed-use commercial and residential campus developed by British Land from the mid-1990s.?

Using natural materials, timber furniture and extensive planting, the pavilions have been designed in response to British Land's vision for revitalising public spaces and pedestrian routes in, through and out of Regent's Place. The three new pavilions are semi-sheltered spaces designed for friends and colleagues to sit and relax between meetings or after-work hours, for outdoor theatre and music performances and for those walking through Regent's Place from the fast-paced Euston Road.

Recently, the Regent's Place "campus" has seen a change in tenants from corporate blue-chips to media, technology and life science companies. This shift has prompted the refurbishment of the office buildings transforming their environmental performance while offering refreshed workspaces better suited to contemporary needs.?

In turn, new tenancies have brought a younger population to the campus and an aspiration to create a livelier and more welcoming public space. The experience of the Covid pandemic further accelerated British Land's ambition to augment a greater sense of natural wellbeing throughout Regent's Place. The challenge for the architects set out in an invited competition brief was?to create a more inviting place for tenants while enlivening connections between Regent's Place and surrounding streets.

Inspired by nature and particularly by the bundles of fine wood kindling encountered in woodlands, the design of the three Regent's Place pavilions gathers thin strips of oak in delicate lattices to enclose visitors while also revealing lush planting around them. Rounded in form, the two larger pavilions have a central oculus that draws people's attention from ground level planting to the sky.

Moving from west to east, the pavilions increase in size. The first welcomes people to gather and sit in conversation. The second encourages children and adults alike to play with a large circular spinning seat positioned in the centre of the path. The final pavilion creates a new tiered performance space for the local theatre group, and a venue for evening and weekend music.?

The finished pavilions extend the transformation of the public realm at Regent's Place. Those working, living and passing through the campus have adopted?a?variety of new places to gather in settings that bring nature imaginatively into the heart of the development encouraging biodiversity with its landscaping by Townsends.

Nex- developed early designs through sketches, study models, and VR simulation to determine the form, size and location of the three pavilions. With these decisions made, Nex-collaborated with design-to-manufacture partners Xylotek to complete computational studies that developed the irregular lattice structures into geometrically rigorous but non-uniform patterns of thin oak laths.

A key challenge for Xylotek has been?to complete the?design?of?the structures so that the laths remain slender while being sufficiently stiff to create self-supporting lattices. The final design took advantage of off-site manufacturing to improve the quality of craftsmanship, to cut waste and reduce on-site assembly time. Using sustainably sourced oak, thin strips were bent and laminated into their final curved shapes on room-sized jigs. Laminated strips were then layered together to make lattices, before being transported to site for final assembly with further layers of loose laths.

What appear to be imaginative, yet effortless and natural, plays of forms demanded structural and constructional ingenuity and forensic attention to detail. The laths forming each pavilion are arranged in four layers, with alternate layers spiralling in opposite directions.? Within each layer the laths share similar geodesic curved shapes, meaning that they could be formed from initially straight oak ribbons. This meant that all the laths in one layer could be formed on a single bending jig, whilst visual dissimilarity was created by varying the laths lengths in a repeating pattern?overlaid?with a degree of randomness.?This process created a visual play between?a?regular underlying pattern and a sense of natural variation.?

There are a total of over 400 laths, made of over 10km of oak lamella strips. Each oak lath has a cross section of 65x40mm and is made of five layers of 8mm oak lamellas. By finger-jointing short lengths of oak end-to-end, lamellas of up to 9.5m length were created.?The glue-lamination was carried out in Xylotek's Bristol workshop on a set of bespoke profiling jigs, and segments each pavilion were preassembled in the workshop, positioned on site, and then overlaid with further laths to create the full 3D lattice of curved oak.

The doorway arches are also formed of glue-laminated oak and are formed in a way that best matches the pavilions' complex curvature with single-direction curved elements.?Surface treatments were applied to the laths in the workshop, to provide both fire protection and add to the durability of the timber.
