RAD+ar：Tanatap环形花园咖啡馆是一个微型的多层绿色空间，升降式动态平台创造了可行走的屋顶景观，并与周围绿地和中央热带户外活动区相连，形成一系列的漂浮圆形剧场。

RAD+ar：Ring Garden Café called Tanatap is a small prototype of multi-leveled greenspace with dynamic platforms that rise and fall to create a walkable roofscape. The structure will be connected to create series of floating amphitheater surrounding green spaces and tropical outdoor activities in the middle.

如果将功能空间和建筑仅仅作为开放式花园的外壳会如何呢？基于这样一个问题，项目的设计旨在展示隐藏在多层花园里的室内空间。设计所创建的空间是序列空间，而非原始空间。项目融合了“共同嬉戏”的核心概念，从而创造一个崭新的、充满活力的、可持续发展的新城市空间，因为在雅加达这样的发展中国家城市，仅是政府来运营公共空间并不可靠。

Started with the question, what if functional spaces and the very definition of building only acted as an envelope of an open garden. Design was to demonstrate a disappearing indoor space, hidden within a simple multi-leveled garden. Spaces that were created became a sequential space, and was not an initial space. At the heart of our project is the idea of playful togetherness. We want this to be a refreshing and dynamic new civic space that is sustainable – businesswise in developing country cities like Jakarta, where government-run public space is unreliable.

建筑师提出了三步设计策略，在大自然中创造一个功能完备的咖啡馆空间。第一步是将所有的现状树木连接起来，以引导和组织游线。其次，串联所有结构，在主入口营造如行走地下般的亲人尺度体验。接着是在大堂/酒吧区域的两侧暗门后，营造出在尺度、色彩、绿化率和透光量方面均有差异化对比的体验空间。这种对现有景观的动态干预手段，确保了新景观在美学上与花园整体风格协调一致。

The architects developed three strategies to create a functional integrated cafe space within the nature. The first approach is to connect all the existing tree as means of circulation for the visitor. Secondly, stringing all the structure to create an underground intimate scale experience in the main entrance. Next, is to create a contrast experience in scale, color, density of nature, and amount of natural sunlight penetration hidden in conceal doors in both wings in the lobby/bar area. This dynamic intervention into the existing landscape to ensure that the new landscape intervention performs aesthetically in harmony with the garden as a whole.

咖啡馆作为一个实验性项目，被用来观察和了解使用者在空间层次结构被重构之后的行为表现。RAD+ar设计事务所利用这个咖啡馆项目来加深了解有关访客在陌生空间环境中的行为模式，这也是为什么馆内大多数家具没有被定义的原因，访客通过结合硬软景的特征来自主选择使用馆内家具时的舒适模式。这也是一项社会性的实验，研究人们在开放空间/花园中是如何不断调整自己对第三空间的感知，而且这种感知行为会根据一天中不同时段内人群的变化而变化。

It was designed as an experimental programming to see and learn on how user will behave once architect restructures the hierarchy of space. RAD+ar uses this project to learn more about visitor behavior in defining spaces they don’t understand, that is why most of the furniture in this café is undefined, blended with the hardscape and feature of the landscape, therefore acted as an experiment of how visitor/user defines their own meaning of comfort in using this furniture. It was seen as a social experiment on how people keep redefining their sense of third space, in open space / garden, and keep changing it to keep up with the crowds in different time of the day.

当访客进入环形花园时，随即会被连接两棵现有树木的栈道包围，室内外空间的界限在此也被模糊。进入花园空间中后，访客会被头顶上方的天窗和上方花园中人们的活动所吸引目光。同心圆空间的中央便是咖啡馆，暗门后的两个空间逐渐变得不那么私密，而是引入了更多的自然光。这两个空间的尽头都是宽敞的多层花园区，间接地让访客去享受更多热带花园所带来的乐趣。

As visitors enter the Ring Garden, they are surrounded pathway bridge that connects 2 existing trees that blurs the definition of indoor and outdoor space. Upon entering the spaces, they were teased by what appears to be sliced of skylight and people activities in garden above. Concentric space with coffee bar in the middle, space branches into 2 spaces behind the concealed door that gradually become less intimate and flooded with more natural light penetrating. Both spaces are leading to the main spacious multi-leveled garden area as the ending and indirectly persuading visitor to enjoy more of what tropical garden could be.

俯瞰这一项目，整个环形花园可以被视作城市与景观之间的过渡空间。从远处看时，它又在地平线上置入城市天际线形象，进入广场后，色彩和光线激发着人们的感官，邀请访客进入环形花园的自然景观之中一探究竟。

In the upper level, the whole ring garden can be seen as a transitional space between the city and the landscape. Looking at the sculpture from further away, it punctures a skyline-like image of a city onto the horizon, but when entering the square, the colour and light, invite the visitors in a sensual way into the natural landscape of the Ring Garden.

咖啡馆外壳结构的主要材料采用了玻璃砖，它模糊了建筑与花园的界限，既保护了内部使用者的隐私，还能保证自然光线的渗透。墙壁结构被整合进玻璃砖之中，以确保其轻盈感，墙壁的轻盈给人带来沉重的材料漂浮在花园上方的感觉，而这种感觉又随着人们在内部的体验逐渐消散。

Glass block is chosen as main materials for the envelope, as it is blurring the definition of whether or not this is considered a building / a garden metaphorically, buffering privacy of customer inside, while offering plenty of natural light from inside. Structure of the walls is integrated within the glass block to ensure its lightness, giving a sensation of a very heavy materials were floating above garden and slowly scattered along with the experience within.

RAD+ar设计事务所将新冠疫情事件视作“机会之窗”，以此倡导和推广更可持续的户外热带商业空间，希望能够鼓励他人借鉴。这体现了一种坚定乐观的态度，表明了如何让资本主义的可持续性在印度尼西亚这样的发展中国家发挥作用。

RAD+ar saw covid-19 pandemic event as a small window of opportunity to more promote more sustainable means of outdoor tropical commercial spaces that hopefully can inspire many other to follow. It is a gesture of unwavering optimism how to make a capitalism- sustainability works in developing-country minded like Indonesia.
