悉尼皇家植物园“花萼”建筑丨澳大利亚悉尼丨PTW Architects

The Calyx 位于悉尼皇家植物园“地下宫殿花园”的最南端，由 PTW Architects 与景观设计事务所 CoCRAM，McGregor Coxall 合作完成。The Calyx 花园的改造将重点放在了创造建筑与环境，以及建筑与人的和谐关系上。

Located at the southernmost part of ”the Underground Palace Garden“ at the Royal Botanic Gardens Sydney, PTW Architects worked with Cockram Construction and McGregor Coxall to design this highly flexible building.

The design of The Calyx builds on the geometry established by the Arc Glasshouse to create an integrated space with indoor and outdoor areas for horticultural exhibitions.

花萼：“花的萼片，通常形成一个螺旋，包围花瓣，并在花蕾周围形成保护层。”

Calyx: “The sepals of a flower, typically forming a whorl that encloses the petals and forms a protective layer around a flower in bud.”

The Calyx 是悉尼皇家植物园的一颗“花园里的宝石”，它融合了艺术、戏剧和植物。而这座建筑物最精彩、最具视觉冲击力的元素就是全新的“虹膜”结构。

A ‘Jewel in the Garden’ the Calyx is a fusion of Art, theatre, and Flora in Sydney’s Royal Botanical Gardens.

The new "Iris" podium is the most fascinating and eye-catching component of the skyscraper.

花萼的整体呈现由 PTW Architects 设计，从远处就能看到这座具有超高辨识度的环形钢结构，它兼具了门廊、教育和零售空间功能。它的中心位置是一个镜面水池，在夜晚它又可以转换成活动空间，通过使用伸缩墙来让展览空间和活动空间合二为一。

The overall presentation of the Calyx, designed by PTW Architects, is noticeable from a distance as a highly recognizable annular steel structure that serves as a porch, educational space, and retail space. The structure also features a mirror pond and event spaces to merge into one space at night.

从圆形大厅的内部看，花萼的整体是一种相机视觉模式。它创造了强烈的电影感官印象。当你经过这里时，穿过柱子，你会体会到景色像被切成一帧一帧的电影画面一般，从而感受到跳跃的节奏感和间距感。它通过其位置和结构轻盈地抵抗现代建筑物体在光线下呈现的稳定性，避免了现代视图的刻板单面广阔空间。

From the interior of the rotunda, a strong cinematic impression is created. The view of the garden is sliced into discrete filmic moments, frame by frame, through the rhythm and spacing of the columns as you pass by. The Calyx is a form of camera for the garden that avoids the stereotypical single-paned expanse of a modern view as much as it resists the stability of a modern architectural object rendered in light through its siting and structural lightness.

The Calyx 的设计建立在由著名的澳大利亚建筑师 Ken Woolley 于 1994 年设计和建造的弧形几何上。PTW 设计团队将新建筑嫁接到弧形的基座上，创造了一个室内外一体的展览空间。

新建筑形式和更加广阔的花园在两条主要路径之间提供了更强大的视觉和物理联系。

该项目建立了一个框架，拆除后在此基础上设计了环形的元素。环形的一半是展示空间，而另一半是开放的室外空间。新的加建和原来的弧形花房形成更自然的连接，使得室内外空间在绿色的环境下连成一体。

Two leading radial paths provide a powerful visual and physical connection between the new built form and the wider gardens. The project built a framework on which the annular element were designed after demolition, with one half serving as a showcase area and the other as a free-standing outdoor area. Comparing to the original pyramid, this new addition fits better to the arc glasshouse.

技术上，PTW 与工程专家和服务顾问紧密合作，积极参与混合系统的推演、协商和交付。

该系统利用了天然浮力“烟囱”效应、遮光以及应对多种环境条件的机械干预方法。

采用了低位空气流通(至人员活动区域)和高位可控遮光栅格和窗户，实现了温室内的自然通风。

Working closely with specialist engineering and services consultants, Jacobs, PTW Architects actively participated in the evolution, negotiation and delivery of a hybrid system that takes advantage of natural buoyancy "chimney" effects, shading and mechanical intervention for a variety of environmental conditions.

The Calyx 是拥有南半球最大绿墙的植物园之一，是悉尼市中心一个独特、引人注目的场所。

在内部，弧形温室拥有着世界各地复杂有机的几何形状植物。

建筑的形态采用比较正统的几何圆形，温室空间容纳了数量惊人的 4 万株植物。它的设计考虑了温度、日照、多样化的植物生长条件，精巧的钢结构和透明起伏的玻璃顶棚，暗示着植物科学研究的进步，以及作为城市景观的引力。

The greenhouse contains a surprising number of 40,000 plants, with the temperature, sunshine and diverse plant growth conditions taken into account in design.

In addition, the exquisite steel structure and transparent undulating glass ceiling suggest the progress of research in plant science and its attraction as an urban landscape.

新设施已经在 2016 年 6 月开放，成为悉尼城市里一个标志性但宁静的补充，作为园艺展示、研究和教育中心。

巧妙智能的设计为游客提供了室内和室外区域的综合体验，每年定期举办不同的活动，是一个活跃的公共展览空间。此外，还可以租用私人活动，包括婚礼和公司活动。

The brand-new building debuted in June 2016 and has established itself as a famous landmark.

The Calyx, which serves as a hub for horticultural exhibition, research, and education, is a famous but peaceful addition to the garden.

The clever design gives visitors a seamless experience of the indoor and outdoor spaces. In addition to hosting annual events and serving as a public exhibition space, it is also available for private events like weddings and business gatherings.

悉尼皇家植物园是个放空的好去处，景色开阔，安静祥和，与悉尼歌剧院只隔一道狭窄的海湾，得天独厚的地理位置使得它成为游客必游之地。

The Sydney Opera House and the Royal Botanic Gardens are only separated by a tiny bay, making it a must-see destination for tourists. The Royal Botanic Gardens is a nice spot to visit with open, serene, and calm surroundings.
